A calcareous and clayey xeric Chromic Haploxerept of a long\uffe2\uff80\uff90term experimental site in Sicily (Italy) was sampled (0\uffe2\uff80\uff9315\uffe2\uff80\uff89cm depth) under different land use management and cropping systems (CSs) to study their effect on soil aggregate stability and organic carbon (SOC). The experimental site had three tillage managements (no till [NT], dual\uffe2\uff80\uff90layer [DL] and conventional tillage [CT]) and two CSs (durum wheat monocropping [W] and durum wheat/faba bean rotation [WB]). The annually sequestered SOC with W was 2\uffc2\uffb775\uffe2\uff80\uff90times higher than with WB. SOC concentrations were also higher. Both NT and CT management systems were the most effective in SOC sequestration whereas with DL system no C was sequestered. The differences in SOC concentrations between NT and CT were surprisingly small. Cumulative C input of all cropping and tillage systems and the annually sequestered SOC indicated that a steady state occurred at a sequestration rate of 7\uffc2\uffb74\uffe2\uff80\uff89Mg\uffe2\uff80\uff89C\uffe2\uff80\uff89ha\uffe2\uff88\uff921\uffe2\uff80\uff89y\uffe2\uff88\uff921. Independent of the CSs, most of the SOC was stored in the silt and clay fraction. This fraction had a high N content which is typical for organic matter interacting with minerals. Macroaggregates (>250\uffe2\uff80\uff89\uffc2\uffb5m) and large microaggregates (75\uffe2\uff80\uff93250\uffe2\uff80\uff89\uffc2\uffb5m) were influenced by the treatments whereas the finest fractions were not. DL reduced the SOC in macroaggregates while NT and CT gave rise to higher SOC contents. In Mediterranean areas with Vertisols, agricultural strategies aimed at increasing the SOC contents should probably consider enhancing the proportion of coarser soil fractions so that, in the short\uffe2\uff80\uff90term, organic C can be accumulated.

However, the effect of soil management on the chemical structure of SOM and on its hydrophobic and hydrophilic components has been little investigated. In this work, the long\uffe2\uff80\uff90term (19\uffe2\uff80\uff89years) effects of two cropping systems (wheat monoculture and wheat/faba bean rotation) and three tillage managements (conventional, reduced, and no tillage) on some chemical characteristics of SOM and their relationships with labile carbon (C) pools were evaluated. Soil samples were taken from the topsoil (0\uffe2\uff80\uff9315\uffe2\uff80\uff89cm) of a Chromic Haploxerert (central Sicily, Italy). After 19\uffe2\uff80\uff89years of different tillage and cropping systems management, total organic C significantly differed among treatments with the labile organic C pools showing the greater amount in no till and in wheat/faba bean plots. Hydrophobic and hydrophilic components of SOM, determined by diffuse reflectance infrared Fourier transform spectroscopy, were mainly affected by cropping system, whereas aromatic components of SOM by tillage. Soil organic matter components and characteristics showed significant correlations with the soil biochemical parameters, confirming the expected synergism between chemical and biochemical properties. This study demonstrated that (i) no tillage and crop rotation improve the chemical and biochemical properties of SOM of Vertisols under semiarid environment; and (ii) tillage management and cropping systems have affected, after 19\uffe2\uff80\uff89years, more the chemical and biochemical properties of SOM than its quantity.

The study included three wet years (1992, 1993, and 1996) and 2 years with average annual rainfall for the area (1994 and 1995). Significant yield differences among treatments, and a yield response to irrigation, were only observed during the 2 years with average rainfall. During all years, the FARMER treatment was over-irrigated and resulted in considerable water losses by runoff and deep percolation. Grain yield response to irrigation during the three wet years was insignificant among the treatments, but significant during the dry years.

We conducted a study to evaluate the effect of three different irrigation intensities on soil N2O and CO2 fluxes and to determine if irrigation management can be used to mitigate N2O emissions from irrigated cotton on black vertisols in South-Eastern Queensland, Australia. Fluxes were measured over the entire 2009/2010 cotton growing season with a fully automated chamber system that measured emissions on a sub-daily basis. Irrigation intensity had a significant effect on CO2 emission. More frequent irrigation stimulated soil respiration and seasonal CO2 fluxes ranged from 2.7 to 4.1 Mg-C ha\u22121 for the treatments with the lowest and highest irrigation frequency, respectively. N2O emission happened episodic with highest emissions when heavy rainfall or irrigation coincided with elevated soil mineral N levels and seasonal emissions ranged from 0.80 to 1.07 kg N2O-N ha\u22121 for the different treatments. Emission factors (EF = proportion of N fertilizer emitted as N2O) over the cotton cropping season, uncorrected for background emissions, ranged from 0.40 to 0.53 % of total N applied for the different treatments. There was no significant effect of the different irrigation treatments on soil N2O fluxes because highest emission happened in all treatments following heavy rainfall caused by a series of summer thunderstorms which overrode the effect of the irrigation treatment. However, higher irrigation intensity increased the cotton yield and therefore reduced the N2O intensity (N2O emission per lint yield) of this cropping system. Our data suggest that there is only limited scope to reduce absolute N2O emissions by different irrigation intensities in irrigated cotton systems with summer dominated rainfall. However, the significant impact of the irrigation treatments on the N2O intensity clearly shows that irrigation can easily be used to optimize the N2O intensity of such a system.", "keywords": ["2.

By Liquid Or Granular Se Fertilisation", "description": "Selenium (Se) is an essential trace element for humans and livestock. In the UK, human Se intake and status has declined since the 1980s. This is primarily due to the increased use of wheat (Triticum aestivum L.) grown in UK soils which are naturally low in Se. The aim of this study was to determine the potential for increasing grain Se concentration in a high-yielding UK wheat crop using fertilisers. The crop response of winter-wheat to Se fertilisation was determined under standard field conditions in two consecutive years at up to 10 sites. Selenium fertilisers were applied as high-volume drenches of sodium selenate solution, or as granular Se-containing products. Yield and harvest index were unaffected by Se fertilisation. Under all treatments, grain Se concentration increased by 16\u201326\u00a0ng Se g\u22121 fresh weight (FW) per gram Se ha\u22121 applied.

We used boosted regression tree (BRT) models to determine the importance of environmental and plant factors for soil respiration and its responsiveness to fertilizer treatments. Leaf area index explained the largest proportion of variation in soil respiration rates (LAI, 45.9\u00a0%) followed by those of site, which had a relative influence of 39.9\u00a0% in the BRT model. Nutrient enrichment enhanced soil respiration only in nine out of 22 forests. Soil respiration in scrub forests showed a positive response to nutrient addition more frequently than taller fringing forests. The response of soil respiration to nutrient enrichment varied with changes in specific leaf area (SLA) and stem extension, with relative influences of 14.4\u00a0%, 13.6\u00a0% in the BRT model respectively.

Biochar samples prepared from chicken manure and green waste were used as soil amendments. Application of biochar significantly reduced NH4NO3 extractable Cd, Cu and Pb concentrations of soils, indicating the immobilization of these metals. Chicken manure-derived biochar increased plant dry biomass by 353 and 572% for shoot and root, respectively with 1% of biochar addition. This might be attributed to reduced toxicity of metals and increased availability of nutrients such as P and K. Both biochars significantly reduced Cd, Cu and Pb accumulation by Indian mustard (Brassica juncea), and the reduction increased with increasing amount of biochar application except Cu concentration. Metal sequential fractionation data indicated that biochar treatments substantially modified the partitioning of Cd, Cu and Pb from the easily exchangeable phase to less bioavailable organic bound fraction.

However, studies describing plant allometric changes are scarcer, but may be crucial to understand the biochar effect. The main aim of the present study is to investigate the effect of biochar on root architecture under field conditions in a tropical setting. The presented work describes a shovelomics (i.e., description of root traits in the field) study on the effect of biochar on maize root architecture. Four field experiments we carried out at two different locations in Zambia, exhibiting non-fertile to relatively fertile soils. Roots of maize crop (Zea mays L.) were sampled from treatments with fertilizer (control) and with a combination of fertilizer and 4\u00a0t.ha\u22121 maize biochar application incorporated in the soil. For the four sites, the average grain yield increase upon biochar addition was 45\u2009\u00b1\u200914\u00a0% relative to the fertilized control (from 2.1\u20136.0 to 3.1\u20139.1 ton ha\u22121). The root biomass was approximately twice as large for biochar-amended plots. More extensive root systems (especially characterized by a larger root opening angle (+14\u2009\u00b1\u200911\u00a0%) and wider root systems (+20\u2009\u00b1\u200915\u00a0%)) were observed at all biochar-amended sites.

No interactive effects between warming and CO2 enrichment were detected. Warming affected the temperature sensitivity of \u03b2-xylosidase but not of the other enzymes.

Unfortunately, optimal sampling of the rangelands for baseline C(s) - the critical first step towards efficient monitoring - has received relatively little attention to date. Moreover, in the rangelands of tropical Australia relatively little is known about how C(s) is influenced by the practice of cattle grazing. To address these issues we used linear mixed models to: (i) unravel how grazing pressure (over a 12-year period) and soil type have affected C(s) and the stable carbon isotope ratio of soil organic carbon (delta(13)C) (a measure of the relative contributions of C(3) and C(4) vegetation to C(s)); (ii) examine the spatial covariation of C(s) and delta(13)C; and, (iii) explore the amount of soil sampling required to adequately determine baseline C(s). Modelling was done in the context of the material coordinate system for the soil profile, therefore the depths reported, while conventional, are only nominal. Linear mixed models revealed that soil type and grazing pressure interacted to influence C(s) to a depth of 0.3 m in the profile. At a depth of 0.5 m there was no effect of grazing on C(s), but the soil type effect on C(s) was significant. Soil type influenced delta(13)C to a soil depth of 0.5 m but there was no effect of grazing at any depth examined. The linear mixed model also revealed the strong negative correlation of C(s) with delta(13)C, particularly to a depth of 0.1 m in the soil profile. This suggested that increased C(s) at the study site was associated with increased input of C from C(3) trees and shrubs relative to the C(4) perennial grasses; as the latter form the bulk of the cattle diet, we contend that C sequestration may be negatively correlated with forage production. Our baseline C(s) sampling recommendation for cattle-grazing properties of the tropical rangelands of Australia is to: (i) divide the property into units of apparently uniform soil type and grazing management; (ii) use stratified simple random sampling to spread at least 25 soil sampling locations about each unit, with at least two samples collected per stratum. This will be adequate to accurately estimate baseline mean C(s) to within 20% of the true mean, to a nominal depth of 0.3 m in the profile.", "keywords": ["2.

We investigated the effects of cattle trampling on soil physical, chemical and microbial properties in a Swiss sub-alpine pasture. About 10% of the study site was bare of vegetation as a result of repeated cattle trampling and the bulk density of these bare steps was 20% higher than of the soils unaffected by trampling. In the upper 25\u00a0cm, soil organic carbon (SOC) concentrations and total SOC stocks were 35% and 20% respectively lower than on the vegetated slope. As compared with the vegetated slope, topsoils of the bare steps featured narrower C:N-ratios and were more enriched in the 15 N isotope, with typical values of deeper soil layers. This indicates that bare soils primarily evolved by erosion and not by a compaction, which might, together with the reduced litter input, explain the lower SOC contents. The abundances of soil microbes, estimated by the concentrations of phospholipid fatty acid (PLFA), were 30% smaller in the bare soils than in the vegetated areas. This depletion was most pronounced for fungi as expressed in the lower concentrations of the fatty acid 18:2\u03c96.9 (45%) and ergosterol (50%). The lower fungal abundance very likely has negative consequences for the stability of the bare soils, since fungi play an important role in the formation of soil aggregates. In summary, our results show that cattle trampling decreases soil carbon storage and alters soil microbial community structure.", "keywords": ["2.

Merr) cultivars selected for tolerance of aluminium (PI416937) or for manganese (Manta). Liming provides calcium (Ca) as well as increasing soil pH. Thus the effect of Ca and pH of soil are difficult to separate. We examined the effects of Ca per se by comparing the response to gypsum and lime amendment on the competitiveness of acid-tolerant and acid-sensitive strains in nodulating soybean in an acid soil. Acid soil was treated with either CaSO4 or CaCO3 and incubated for 2 weeks before sowing soybean seed. Two acid-sensitive and two acid-tolerant B.\u00a0japonicum strains were mixed with each other (one acid-sensitive plus one acid-tolerant) and were inoculated onto soybean seeds at the rate of 106cfu\u00a0seed\u22121. Soil pH, as amended by lime addition, had more effect on nodulation than Ca addition in the form of gypsum. The response was affected by cultivar and strain in a complicated fashion with a marked strain\u00a0\u00d7\u00a0cultivar interaction. One acid-tolerant strain formed most nodules with both cultivars in the unamended soil of pH 4.36 in competition with one acid-sensitive strain. The same acid-tolerant strain was not competitive against the second acid-sensitive strain with Manta but was with PI416937. The second acid-tolerant strain was not competitive with either acid-sensitive strain in unamended and gypsum treated soils. It was only competitive with PI416937 in limed soil, a rather surprising result. Inoculation of this soil with no native soybean nodulating strains, increased shoot weight, %N, N uptake. N2-fixation was greatly increased by inoculation and lime addition, and to a lesser extent by gypsum addition for Manta. This experiment indicates that addition of Ca per se as gypsum to an acid soil has little effect on symbiotic performance, but changing pH by liming has a major effect, that both soybean cultivar and B.\u00a0japonicum strain influence the competitiveness of strains in acid soil and that acid-tolerance does not necessarily increase a strain's competitiveness.", "keywords": ["0301 basic medicine", "2.

The experiment consisted of four treatments viz: soil only (control), soil\u00a0+\u00a0lime, soil\u00a0+\u00a0wheat, and soil\u00a0+\u00a0lime\u00a0+\u00a0wheat. We measured CO2-C effluxes at 7, 43 and 98 days after planting (DAP) and leachate was collected at 56 and 101 DAP. The soil CO2-C efflux rate increased significantly with lime addition at 7 and 43 DAP compared to control. At 43 DAP, the largest increase in CO2-C effluxes was observed in the lime\u00a0+\u00a0wheat treatment. However, at 98 DAP similar CO2-C effluxes were observed from wheat and lime\u00a0+\u00a0wheat treatments, suggesting that most of the lime was dissolved in the lime\u00a0+\u00a0wheat treatment. Both DOC and DIC concentrations in the leachate increased significantly with lime and wheat only treatments (cf. control). In contrast to DOC, there was an increase in the DIC concentration in the soil leachate from lime\u00a0+\u00a0wheat treatment columns at 101 DAP (significant wheat\u00a0\u00d7\u00a0lime interaction), thus, accentuating the pronounced role of wheat roots.

To investigate the relationship between the C and N mineralization rates and the possible consequences in terms of C storage and N availability, we incubated ryegrass-derived PyOM (pyrolyzed at 450\u00a0\u00b0C) enriched in 13 C (4.33 atom %) in a forest Cambisol for 158 days with and without mineral N addition. We determined PyOM and native soil organic C mineralization, NH 4 + and NO 3 \u2212 contents in the soil, gross N mineralization, phenol-oxidase and protease activities, and microbial biomass throughout the incubation experiment and the incorporation of PyOM in microbial biomass at the end of the experiment (158 days). We determined that 4.3% of the initial PyOM-C was mineralized after 158 days. Moreover, PyOM induced a strongly positive priming effect within the first 18 days; a negative priming effect was observed from Days 18 to 158. The initial increase in organic matter mineralization corresponded to a higher gross N mineralization and NH 4 + content in the PyOM-treated soil than in the untreated soil.

The concept that different resources co-limit plant productivity has been well studied. However, co-limitation of soil microbial communities by multiple resources has not been as thoroughly investigated. Specifically, it is not clearly understood how microbial communities respond to shifts in multiple interacting resources such as water, temperature, and nitrogen (N), in the context of global change. To test the effects of these various resources on soil microorganisms, we established a field experiment with temperature and N manipulation in three grasslands of northern China, where there is a decrease in precipitation from east to west across the region. We found that microbial responses to temperature depended upon seasonal water regimes in these temperate steppes. When there was sufficient water present, warming had positive effects on soil microorganisms, suggesting an interaction between water and increases in temperature enhanced local microbial communities. When drought or alternating wet\u2013dry stress occurred, warming had detrimental effects on soil microbial communities. Our results also provide clear evidence for serial co-limitation of microorganisms by water and N at the functional group and community levels, where water is a primary limiting factor and N addition positively affects soil microorganisms only when water is sufficient. We predict that future microbial responses to changes in temperature and N availability could be seasonal or exist only in non-drought years, and will strongly rely on future precipitation regimes.", "keywords": ["2.

While benefits of NT, accompanied by stubble retention, are almost universal for soil erosion control, effects on soil organic matter and other soil properties are inconsistent, especially in a semi-arid, subtropical environment. We examined the effects of tillage, stubble and fertilizer management on the distribution of organic matter and nutrients in the topsoil (0\u201030 cm) of a Luvisol in a semi-arid, subtropical environment in southern Queensland, Australia. Measurements were made at the end of 9 years of NT, reduced till (RT) and conventional till (CT) practices, in combination with stubble retention and fertilizer N (as urea) application strategies for wheat (Triticum aestivum L.) cropping. In the top 30 cm depth, the mean amount of organic C increased slightly after 9 years, although it was similar under all tillage practices, while the amount of total N declined under CTand RT practices, but not under NT. In the 0\u201010 cm depth, the amounts of organicC and total N were significantly greater under NT than under RTor CT. No-till had 1.94 Mg ha 1 (18%) more organicC and 0.20 Mg ha 1 (21%) more total N than CT. In the 0\u201030 cm depth, soil under NT practice had 290 kg N ha 1 more than that under the CT practice, most of it in the top 10 cm depth. Microbial biomass N was similar for all treatments. Under NT, there was a concentration gradient in organic C, total N and microbial biomass N, with concentrations decreasing from 0\u20102.5 to 5\u201010 cm depths. SoilpHwasnotaffectedbytillageorstubbletreatmentsinthe0\u201010 cmdepth,butdecreasedsignificantlyfrom7.5to7.2withN fertilizer application.

Therefore, NTand RT practices resulted in significant changes in soil organic C and N and exchangeable cations in the topsoil of a Luvisol, when compared with CT. The greater organic matter accumulation close to the soil surface and solute movement in these soils under NT practice would be beneficial to soil chemical and physical status and crop production in the long-term, whereas the concentration of nutrients such as P and K in surface layers may reduce their availability to crops. # 2006 Elsevier B.V.

Compared to CT, the controlled traffic treatments significantly reduced soil bulk density in 10-20 cm soil layer, significantly increased soil water content in the 0-150 cm soil profile at sowing, 9.3% for NTCN, 9.6% for STCN. These effects were greater in dry seasons, thus reducing the yearly variation in water conservation. Consequently, mean wheat yield of NTCN, STCN and CT were 3.25, 3.27 and 3.05 t ha-1, respectively, in which controlled traffic treatments increased by 6.9% with less yearly variation, compared to traditional tillage. Furthermore, controlled traffic had greater economic benefits than conventional tillage. Within controlled traffic treatments, NTCN showed better overall performance.

The effects of land use change of grazed pastures on in situ fluxes of nitrous oxide (N2O) and methane (CH4) from soil were examined across 3 forest types in Australian temperate, Mediterranean, and subtropical regions, using a network of paired pasture\uffe2\uff88\uff92forest sites, representing 3 key stages of forest stand development: establishment, canopy-closure, and mid to late rotation. During the 12-month study, soil temperature ranged from \uffe2\uff80\uff936\uffc2\uffb0 to 40\uffc2\uffb0C and total rainfall from 487 to 676\uffe2\uff80\uff89mm.

The information derived from this study can be used to improve the capacity of models for GHG accounting (e.g. FullCAM, which underpins Australia\uffe2\uff80\uff99s National Carbon Accounting System) to estimate N2O and CH4 fluxes resulting from land use change from pasture to forest in Australia. There is still, however, a need to test model outputs against continuous N2O and CH4 measurements over extended periods of time and across a range of sites with similar land use, to increase confidence in spatial and temporal estimates at regional levels.

There were significant seasonal fluctuations in TOC contents at different stages of the fallow period, and the lowest levels of TOC and treatment effects were observed in the late fallow period. Density fractionation of soil organic C showed that light fraction C (<1.6 g/cm3) declined rapidly during the fallow period and did not accumulate substantially in soil.

Total And Labile Carbon", "description": "Mulga (Acacia aneura) dominated vegetation originally occupied 11.2 Mha in Queensland, of which 12% has been cleared, mostly for pasture production, but some areas are also used for cereal cropping. Since mulga communities generally occupy fragile soils, mostly Kandosols and Tenosols, in semi-arid environments, clearing of mulga, which continues at a rate of at least 35 000 ha/year in Queensland, has considerable impact on soil organic carbon (C), and may also have implications for the greenhouse gas emissions associated with land use change in Australia. We report here the changes in soil C and labile C pools following mulga clearing to buffel pasture (Cenchrus ciliaris) and cereal (mostly wheat) cropping for 20 years in a study using paired sites. Soil organic C in the top 0.05 m of soil declined by 31% and 35% under buffel pasture and cropping, respectively. Land use change from mulga to buffel and cropping led to declines in soil organic C of 2.4 and 4.7 t/ha, respectively, from the top 0.3 m of soil. Using changes in the \uffce\uffb413C values of soil organic C as an approximate representation of C derived from C3 and C4 vegetation from mulga and buffel, respectively, up to 31% of soil C was C4-derived after 20 years of buffel pasture. The turnover rates of mulga-derived soil C ranged from 0.035/year in the 0\uffe2\uff80\uff930.05 m depth to 0.008/year in the 0.6\uffe2\uff80\uff931 m depths, with respective turnover times of 29 and 133 years. Soil organic matter quality, as measured by the proportion/amount of labile fraction C (light fraction, < 1.6 t/m3) declined by 55% throughout the soil profile (0\uffe2\uff80\uff931 m depth) under both pasture and cropping. There is immediate concern for the long-term sustainable use of land where mulga has been cleared for pasture and/or cropping with a continuing decline in soil organic matter quality and, hence, soil fertility and biomass productivity. In addition, the removal of mulga forest over a 20-year period in Queensland for pasture and cropping may have contributed to the atmosphere at least 12 Mt CO2-equivalents.

This paper reports the soil physical properties after 9 years of dryland wheat production under these treatments, and the substantial improvements seen in soils under controlled traffic. Compared with conventional tillage, controlled traffic significantly reduced soil bulk density in the 0\uffe2\uff80\uff930.15\uffe2\uff80\uff89m soil layer, and increased total porosity in the 0\uffe2\uff80\uff930.60\uffe2\uff80\uff89m soil layer, where macroporosity (>60\uffe2\uff80\uff89\uffc2\uffb5m) and mesoporosity (0.2\uffe2\uff80\uff9360\uffe2\uff80\uff89\uffc2\uffb5m) increased at the expense of microporosity (<0.2\uffe2\uff80\uff89\uffc2\uffb5m).

Organic matter and its constituents, especially total organic C, organic C in the light fraction, total N and mineralizable N, were affected most by cultivation, showing decreases of 19-67% overall. Other soil properties probably associated with organic matter, including bulk density and DTPA (diethylenetriaminepentaacetic acid) extractable manganese, were also significantly affected by cultivation in all soils. Soil properties affected least by cultivation were concentrations of inorganic phosphorus, total and exchangeable potassium, calcium carbonate, and dithionite extractable iron and aluminium. Most other soil properties studied (organic P, total sulfur, pH, exchangeable magnesium and sodium, exchangeable sodium percentage, and oxalate-extractable iron and aluminium) were affected by cultivation in at least four soils. Four factors accounted for 70% of the total variation among the 45 soil properties considered. They appeared to represent organic matter, clay colloids, iron and aluminium oxides, and soluble salts. Dry matter yield and/or N uptake of winter cereal crops (wheat and barley) measured in 1983 showed significant decreasing trends with period of cultivation in all soils.

However, rates of SOC increase can vary depending on cropping system, climate, and soil type, making the quantification of carbon change difficult on a regional level. Various long-term trials and commercial sites throughout Queensland were used to compare rates of SOC change under CT and NT management in cropping soils, and to determine how climate and soil type interact to influence rates of change. It was observed that NT management was not capable of increasing SOC stocks under the crop\uffe2\uff80\uff93fallow rotation systems practised throughout Queensland, and was unlikely even to hold SOC stocks steady under current management practices. However, SOC losses under NT systems did appear to be slower than under CT, indicating that NT may slow SOC loss following a period of organic carbon input, for example, from a pasture ley. On a regional scale, biomass production (estimated through remote sensing), climate (specifically the vapour pressure deficit), and soil sand content could be used to adequately predict SOC stocks on commercial sites, indicating the importance of considering these factors when assessing SOC stocks following management change across the region.

Organic C accretion was also measured to ascertain the changes in organic matter content. The systems, which were studied only during 1989 and 1990, were a grass+legume ley (purple pigeon grass, Rhodes grass, lucerne, annual medics) of 4 years duration followed by wheat; a 2-year rotation of wheat (lucerne undersown) and lucerne; a 2-year rotation of wheat (medic undersown) and medic; a 2-year rotation of chickpea and wheat; and continuous wheat as control. Soil total N and organic C significantly increased in the 0\uffe2\uff80\uff9310 cm soil layer only under the grass+legume ley. There was no significant change in the soil C/N ratio. Plant residues contained from 52 to 104 kg N/ha in 1990 at the end of the legume phase, with high values for root N in the grass+legume ley. A comparison of N accretion versus fixation at the end of the legume-based systems in 1990 showed that net accumulation of N exceeded fixation in soil under lucerne and grass+legume leys; in the latter, net accumulation of 779 kg N/ha over 3.75 years was measured compared with 384 kg N/ha for N2 fixation. Part of the accumulation of N may have been due to uptake of NH4-N from the deep subsoil. Although values for soil mineral N (0\uffe2\uff80\uff93120 cm) were low at the end of all the legume-based systems, a deep subsoil (120\uffe2\uff80\uff93300 cm) accumulation of NH4-N was found in all treatments. The nitrogen mineralisation potentials (No) for 0\uffe2\uff80\uff9310 cm depth samples taken at the end of the legume phase in 1989 were higher in all the legume-based systems (105\uffe2\uff80\uff93182 mg N/kg) than the wheat control (57 mg N/kg).

The rapid chemical tests, hot KCl extraction and the autoclave index, showed small treatment effects and did not appear to be useful availability indices. The pasture management (graced v. mown and removed) had no significant effect on total N, organic C and N availability indices in this alkaline Vertisol during the study period.

Most irrigation water comes from groundwater. Persistent drought and increased competition for water resources threaten long-term viability of groundwater resources, which motivated our research to develop strategies to increase water productivity without noticeable reduction in maize yield. Results from previous research at the University of Nebraska-Lincoln (UNL) experiment stations in 2005 and 2006 found that it was possible to substantially reduce irrigation amounts and increase irrigation water use efficiency (IWUE) and crop water use efficiency (CWUE) (or crop water productivity) with little or no reduction in yield using an irrigation regime that applies less water during growth stages that are less sensitive to water stress. Our hypothesis was that a soil moisture-based irrigation management approach in research fields would give similar results in large production-scale, center-pivot irrigated fields in Nebraska. To test this hypothesis, IWUE, CWUE, and grain yields were compared in extensive on-farm research located at eight locations over two years (16 site-years), representing more than 600 ha of irrigated maize area. In each site-year, two contiguous center-pivot irrigated maize fields with similar topography, soil properties, and crop management practices received different irrigation regimes: one was managed by UNL researchers, and the other was managed by the farmer at each site. Irrigation management in farmer-managed fields relied on the farmers\u2019 traditional visual observations and personal expertise, whereas irrigation timing in the UNL-managed fields was based on pre-determined soil water depletion thresholds measured using soil moisture sensors, as well as crop phenology predicted by a crop simulation model using a combination of real-time (in-season) and historical weather data. The soil moisture-based irrigation regime resulted in greater soil water depletion, which decreased irrigation requirements and enabled more timely irrigation management in the UNL-managed fields in both years (34% and 32% less irrigation application compared with farmer-managed fields in 2007 and 2008, respectively). The average actual crop evapotranspiration (ETC) for the UNL- and farmer-managed fields for all sites in 2007 was 487 and 504 mm, respectively. In 2008, the average UNL and average farmer-managed field had seasonal ETC of 511 and 548 mm, respectively. Thus, when the average of all sites is considered, the UNL-managed fields had 3% and 7% less ETC than the farmer-managed fields in 2007 and 2008, respectively, although the percentage was much higher for some of the farmer-managed fields. In both years, differences in grain yield between the UNL and farmer-managed fields were not statistically significant (p = 0.75). On-farm implementation of irrigation management strategies resulted in a 38% and 30% increase in IWUE in the UNL-managed fields in 2007 and 2008, respectively. On average, the CWUE value for the UNL-managed fields was 4% higher than those in the farmer-managed fields in both years. Reduction in irrigation water withdrawal in UNL-managed fields resulted in $32.00 to $74.10 ha-1 in 2007 and $44.46 to $66.50 ha-1 in 2008 in energy saving and additional net return to the farm income. The results from this study can have significant positive implications in future irrigation management of irrigated maize systems in regions with similar soil and crop management practices.", "keywords": ["Civil and Environmental Engineering", "0106 biological sciences", "571", "Environmental Engineering", "550", "Other Civil and Environmental Engineering", "2204 Biomedical Engineering", "1107 Forestry", "01 natural sciences", "630", "Engineering", "1102 Agronomy and Crop Science", "1106 Food Science", "1111 Soil Science", "2.

Highest concentrations of organic C and total N were found in the surface soil (0\uffe2\uff80\uff930.1 m) with a combination of no\uffe2\uff80\uff90tillage, crop residue retained, and fertilizer N. Mineralizable N followed similar trends. Soil pH to 0.3\uffe2\uff80\uff90m depth and electrical conductivity to 1.2\uffe2\uff80\uff90m depth were significantly lower under no\uffe2\uff80\uff90tillage than under conventional tillage. Aggregation index of the surface soil (0\uffe2\uff80\uff930.1 m), was higher under no\uffe2\uff80\uff90tillage. The ESP was lowest in the surface soil (0\uffe2\uff80\uff930.04 m) under no\uffe2\uff80\uff90tillage with crop residues retained; the soil profile (0\uffe2\uff80\uff931.2 m) under this treatment also contained far less NaCl\uffe2\uff80\uff90equivalent salts (0.8 Mg ha\uffe2\uff88\uff921) than under conventional tillage with crop residue burned (7.3 Mg ha\uffe2\uff88\uff921). Available water and nitrate were lower in the surface soil but greater at depths (0.6\uffe2\uff80\uff931.2 m) under no\uffe2\uff80\uff90tillage than in tilled soil. Thus tillage and crop residue management can substantially affect soil organic matter and microbial activity in the surface layers, and water relations and salt movement to at least 1.2\uffe2\uff80\uff90m depth, even in a fine\uffe2\uff80\uff90textured Vertisol.
