These alterations in N-cycling have been attributed to a combination of physicochemical change, alterations in microbial community ecology and pervading climatic conditions. This study investigated seasonal bacterial community change over two years in combination with a short-term winter study of N-transformations under bovine urine patches. A silt-loam pastoral soil in Canterbury, New Zealand was amended with either 0, 15 or 30\u00a0t\u00a0ha \u22121  of  Pinus radiata  biochar (pyrolysed at \u223c450\u00a0\u00b0C) and bovine urine was added to patches within the 0 and 30\u00a0t\u00a0ha \u22121  biochar amended plots (designated as 0\u00a0U and 30\u00a0U treatments, where U indicates \u2018urine\u2019).  No discernible differences in bacterial community structure were observed during the two year study or the short term N-transformation study when comparing non-amended and biochar-amended soil. Differences in bacterial community structure were only evident when comparing seasons, with data pertaining to each season from successive years clustering together. During the short-term N-transformation study, bacterial communities formed 3 distinct clusters corresponding to elevated levels of urine derived NH 4  + -N (days 0\u201310), increases in NO 3  \u2212 -N and N 2 O (days 10\u201322) and a decline in NO 3  \u2212 -N and N 2 O (day 20 onward). Biochar amendment did increase the relative abundance of up to 50% of individual operational taxonomic units (OTUs or \u2018species\u2019), including key nitrite oxidisers and nitrate reducers. Biochar amendment did not affect the concentrations of inorganic-N compounds.  The  nir S (nitrite reductase) gene became elevated in the 30\u00a0U treatment relative to the 0\u00a0U treatment \u223c10 days after the initial urine application. The  nos Z (nitrous oxide reductase) gene became elevated in the 30\u00a0U plots during the latter part of the experiment.  Conclusions:  \u2022   Biochar did not have a significant impact on the microbial community structure in pastoral soil over the course of two years.   \u2022   The relative proportion of nitrifiers and denitrifiers increased in biochar amended soils subjected to large influxes of urine derived N.   \u2022   Differences in N-transformation dynamics in the presence of biochar during the winter months were not statistically significant.", "keywords": ["2.

The objective of this work was to verify if the simultaneous use of the information obtained from tension infiltrometers and water release curves contribute to a better understanding of the impacts of different long-term management systems on the pore space of agricultural soils. The study was carried out on the Flat Pampa in Santa Fe, Argentina, in two types of typical Argiudolls with a silty-loam surface soil texture. The following treatments were evaluated: a) no-till with corn\u2013wheat/soybean rotation (NT-R), and b) conventional tillage with wheat/soybean sequence (CT-S) at Galvez; and a) no-till with corn\u2013soybean\u2013wheat/soybean rotation (NT-R), and b) no-till with wheat/soybean sequence (NT-S) at Videla. Tension values of 0, 1.5 and 3\u00a0cm were applied using tension infiltrometers with the aim of obtaining soil hydraulic conductivity measurements ( K  0 ,  K  1.5 , and  K  3 ), and several hydraulic parameters (pore size, pore number, effective macroporosity, conducting macroporosity ( e  ( a , b ) ), water flow and water flow decrease). Undisturbed soil cores were collected to determine water release curves (WRC) and soil bulk density (Db). The total macroporosity (Ma) and pore size frequency curve were determined from the fitted model of the WRC. Macropore connectivity was calculated using  e  ( a , b )  and Ma. In Galvez, the Db values,  K  at all tensions, the number of effective pores, the mean pore radius and the effective macroporosity were significantly higher for NT-R. The conducting and total macroporosity values were similar in NT-R and CT-S, but the pores had better continuity in NT-R. In Videla, only  K  0  and  K  1.5  showed statistical differences in favor of NT-R. This treatment also had a greater number of effective pores, and higher effective, conducting and total macroporosity values, apart from the overall better pore connectivity. There were no significant differences between the NT-R and CT-S for Db and  K  3 . The evaluated indicators determined that the pore network characteristics are affected not only by tillage system, but also by the crops chosen for the rotation. When used jointly, tension infiltrometers and water release curves can be very useful tools for monitoring the evolution of the soils physical conditions.", "keywords": ["2.

Therefore, we evaluated the effects of long-term tillage and residue management on SOC dynamics in a Chromic Luvisol (red clay soil) and Areni-Gleyic Luvisol (sandy soil) in Zimbabwe. At the time of sampling the soils had been under conventional tillage (CT), mulch ripping (MR), clean ripping (CR) and tied ridging (TR) for 9 years. Soil was fully dispersed and separated into 212\u20132000 mm (coarse sand), 53\u2013212 mm (fine sand), 20\u201353 mm (coarse silt), 5\u201320 mm (fine silt) and 0\u20135 mm (clay) size fractions. The whole soil and size fractions were analyzed for C content. Conventional tillage treatments had the least amount of SOC, with 14.9 mg C g \ufffd 1 soil and 4.2 mg C g \ufffd 1 soil for the red clay and sandy soils, respectively. The highest SOC content was 6.8 mg C g \ufffd 1 soil in the sandy soil under MR, whereas for the red clay soil, TR had the highest SOC content of 20.4 mg C g \ufffd 1 soil. Organic C in the size fractions increased with decreasing size of the fractions. In both soils, the smallest response to management was observed in the clay size fractions, confirming that this size fraction is the most stable. The coarse sand-size fraction was most responsive to management in the sandy soil where MR had 42% more organic C than CR, suggesting that SOC contents of this fraction are predominantly controlled by amounts of C input. In contrast, the fine sand fraction was the most responsive fraction in the red clay soil with a 66% greater C content in the TR than CT. This result suggests that tillage disturbance is the dominant factor reducing C stabilization in a clayey soil, probably by reducing C stabilization within microaggregates. In conclusion, developing viable conservation agriculture practices to optimize SOC contents and long-term agroecosystem sustainability should prioritize the maintenance of C inputs (e.g. residue retention) to coarse textured soils, but should focus on the reduction of SOC decomposition (e.g. through reduced tillage) in fine textured soils. # 2006 Elsevier B.V.

In this study, we analysed the effect of long-term tillage and irrigation practices on the surface structure of an arable soil in New Zealand. Our hypothesis was that topsoil structure would change under intensification of arable production, affecting gas exchange. Intact soil cores were collected from plots under intensive tillage (IT) and direct drill (DD), irrigated or rainfed. In total, 32 cores were scanned by X-ray computed tomography (CT) to derive the pore network &amp;gt;30\u00b5m. The cores were then used to measure soil-gas diffusivity, air-permeability and air-filled porosity of pores close to the resolution of the X-ray CT scans, namely \u226530\u00b5m. The gas measurements allow the calculation of pore-network connectivity and tortuosity parameters, which were compared with the CT-derived structural characteristics. Long-term irrigation had little effect on any of the parameters analysed. Total porosity tended to be lower under IT than DD, whereas the CT-derived porosity was comparable. Both the CT-derived mean pore diameter (MPD) and other morphological parameters, as well as gas measurement-derived parameters, highlighted a less developed structure under IT. The differences in the functional pore-network structure were attributed to SOC depletion and the mechanical disturbance through IT. Significant correlations between CT-derived parameters and functional gas transport parameters such as tortuosity and MPD were found, which suggest that X-ray CT could be useful in the prediction of gas transport. </p></article>", "keywords": ["AGRICULTURE", "soil structure.", "P-parameter", "Soil structure", "carbon depletion", "MANAGEMENT", "COMPUTED-TOMOGRAPHY", "PERMEABILITY", "CONSERVATION TILLAGE", "Dexter index", "Intensive tillage", "SOIL ORGANIC-CARBON", "carbon depletion; Dexter index; intensive tillage; P -parameter; soil organic carbon; soil structure.; Environmental Science (miscellaneous); Soil Science; Earth-Surface Processes", "P -parameter", "LOAM SOIL", "Soil organic carbon", "POROSITY", "04 agricultural and veterinary sciences", "15.

Adopting soil and crop management practices that conserve or enhance soil structure is critical for supporting the sustainable adaptation of agriculture to climate change, as it should help maintain agricultural production in the face of increasing drought or water excess without impairing environmental quality. In this paper, we evaluate the evidence for this assertion by synthesizing the results of 34 published meta-analyses of the effects of such practices on soil physical and hydraulic properties relevant for climate change adaptation in European agriculture. We also review an additional 127 meta-analyses that investigated synergies and trade-offs or help to explain the effects of soil and crop management in terms of the underlying processes and mechanisms. Finally, we identify how responses to alternative soil\u2013crop management systems vary under contrasting agro-environmental conditions across Europe. This information may help practitioners and policymakers to draw context-specific conclusions concerning the efficacy of management practices as climate adaptation tools. Our synthesis demonstrates that organic soil amendments and the adoption of practices that maintain \u201ccontinuous living cover\u201d result in significant benefits for the water regulation function of soils, mostly arising from the additional carbon inputs to soil and the stimulation of biological processes. These effects are clearly related to improved soil aggregation and enhanced bio-porosity, both of which reduce surface runoff and increase infiltration. One potentially negative consequence of these systems is a reduction in soil water storage and groundwater recharge, which may be problematic in dry climates. Some important synergies are reductions in nitrate leaching to groundwater and greenhouse gas emissions for nonleguminous cover crop systems. The benefits of reducing tillage intensity appear much less clear-cut. Increases in soil bulk density due to traffic compaction are commonly reported. However, biological activity is enhanced under reduced tillage intensity, which should improve soil structure and infiltration capacity and reduce surface runoff and the losses of agro-chemicals to surface water. However, the evidence for these beneficial effects is inconclusive, while significant trade-offs include yield penalties and increases in greenhouse gas emissions and the risks of leaching of pesticides and nitrate. Our synthesis also highlights important knowledge gaps on the effects of management practices on root growth and transpiration. Thus, conclusions related to the impacts of management on the crop water supply and other water regulation functions are necessarily based on inferences derived from proxy variables. Based on these knowledge gaps, we outlined several key avenues for future research on this topic.                     </p></article>", "keywords": ["550", "Soil Science", "N2O EMISSIONS", "ECOSYSTEM SERVICES", "COVER CROPS", "12.

In this study, we analysed the effect of long-term tillage and irrigation practices on the surface structure of an arable soil in New Zealand. Our hypothesis was that topsoil structure would change under intensification of arable production, affecting gas exchange. Intact soil cores were collected from plots under intensive tillage (IT) and direct drill (DD), irrigated or rainfed. In total, 32 cores were scanned by X-ray computed tomography (CT) to derive the pore network &amp;gt;30 \u00b5m. The cores were then used to measure soil-gas diffusivity, air-permeability and air-filled porosity of pores close to the resolution of the X-ray CT scans, namely =30 \u00b5m. The gas measurements allow the calculation of pore-network connectivity and tortuosity parameters, which were compared with the CT-derived structural characteristics. Long-term irrigation had little effect on any of the parameters analysed. Total porosity tended to be lower under IT than DD, whereas the CT-derived porosity was comparable. Both the CT-derived mean pore diameter (MPD) and other morphological parameters, as well as gas measurement-derived parameters, highlighted a less developed structure under IT. The differences in the functional pore-network structure were attributed to SOC depletion and the mechanical disturbance through IT. Significant correlations between CT-derived parameters and functional gas transport parameters such as tortuosity and MPD were found, which suggest that X-ray CT could be useful in the prediction of gas transport.</p></article>", "keywords": ["AGRICULTURE", "soil structure.", "P-parameter", "Soil structure", "carbon depletion", "MANAGEMENT", "COMPUTED-TOMOGRAPHY", "PERMEABILITY", "CONSERVATION TILLAGE", "Dexter index", "Intensive tillage", "SOIL ORGANIC-CARBON", "carbon depletion; Dexter index; intensive tillage; P -parameter; soil organic carbon; soil structure.; Environmental Science (miscellaneous); Soil Science; Earth-Surface Processes", "P -parameter", "LOAM SOIL", "Soil organic carbon", "POROSITY", "04 agricultural and veterinary sciences", "15.
