Excess water can induce flooding stress resulting in yield loss, even in wetland crops such as rice (Oryza). However, traits from species of wild Oryza have already been used to improve tolerance to abiotic stress in cultivated rice. This study aimed to establish root responses to sudden soil flooding among eight wild relatives of rice with different habitat preferences benchmarked against three genotypes of O. sativa. Plants were raised hydroponically, mimicking drained or flooded soils, to assess the plasticity of adventitious roots. Traits included were apparent permeance (PA) to O2 of the outer part of the roots, radial water loss, tissue porosity, apoplastic barriers in the exodermis, and root anatomical traits. These were analysed using a plasticity index and hierarchical clustering based on principal component analysis. For example, O. brachyantha, a wetland species, possessed very low tissue porosity compared with other wetland species, whereas dryland species O. latifolia and O. granulata exhibited significantly lower plasticity compared with wetland species and clustered in their own group. Most species clustered according to growing conditions based on PA, radial water loss, root porosity, and key anatomical traits, indicating strong anatomical and physiological responses to sudden soil flooding.
Intensive agriculture is dominated by monocultures of high\uffe2\uff80\uff90yielding plants that receive large applications of nitrogen (N) fertilizers to boost plant productivity. However, these systems have low N use efficiency (NUE) as fertilized plants generally take up less than half of the N applied. A large fraction of the remainder N is susceptible to be lost from the agroecosystem generating a cascade of environmental and socio\uffe2\uff80\uff90economic problems. Climate change and projected global increases in fertilizer use pose further risks to N losses and yield stability.
We review and translate concepts from ecology in natural systems to demonstrate that NUE in intensive agroecosystems can be strongly increased by fine\uffe2\uff80\uff90tuning the traits of the plant communities to the levels of N fertilization intensity.
We present key plant traits of importance for N\uffe2\uff80\uff90cycling (architectural, morphological and physiological traits, as well as symbiotic associations and exudation patterns); discuss ecological (with soil fauna and N\uffe2\uff80\uff90cycling microbial communities) and agronomic interactions of this approach; propose interdisciplinary methodologies for future research ranging from pot to global scales; and highlight possible solutions leading to an optimal balance between N fertilizer use and productivity.
Synthesis and applications. By showing the strong links between plant traits and nitrogen (N) cycling, our work opens possibilities to test ecologically informed hypotheses across gradients of soil fertility and N fertilizer management intensity, setting a research agenda for the coming years. Accordingly, the choice of plant species based on their functional traits will play a central role for the development of modern and productive agroecosystems that retain and use N more efficiently.
Human activities have greatly increased the availability of biologically active forms of nutrients [e.g., nitrogen (N), phosphorous (P), potassium (K), magnesium (Mg)] in many soil ecosystems worldwide. Multi\uffe2\uff80\uff90nutrient fertilization strongly increases plant productivity but may also alter the storage of carbon (C) in soil, which represents the largest terrestrial pool of organic C. Despite this issue is important from a global change perspective, key questions remain on how the single addition of N or the combination of N with other nutrients might affect C sequestration in human\uffe2\uff80\uff90managed soils. Here, we use a 19\uffe2\uff80\uff90year old nutrient addition experiment on a permanent grassland to test for nutrient\uffe2\uff80\uff90induced effects on soil C sequestration. We show that combined NPKMg additions to permanent grassland have \uffe2\uff80\uff98constrained\uffe2\uff80\uff99 soil C sequestration to levels similar to unfertilized plots whereas the single addition of N significantly enhanced soil C stocks (N\uffe2\uff80\uff90only fertilized soils store, on average, 11\uffc2\uffa0t C\uffc2\uffa0ha\uffe2\uff88\uff921 more than unfertilized soils). These results were consistent across grazing and liming treatments suggesting that whilst multi\uffe2\uff80\uff90nutrient additions increase plant productivity, soil C sequestration is increased by N\uffe2\uff80\uff90only additions. The positive N\uffe2\uff80\uff90only effect on soil C content was not related to changes in plant species diversity or to the functional composition of the plant community. N\uffe2\uff80\uff90only fertilized grasslands show, however, increases in total root mass and the accumulation of organic matter detritus in topsoils. Finally, soils receiving any N addition (N only or N in combination with other nutrients) were associated with high N losses. Overall, our results demonstrate that nutrient fertilization remains an important global change driver of ecosystem functioning, which can strongly affect the long\uffe2\uff80\uff90term sustainability of grassland soil ecosystems (e.g., soils ability to deliver multiple ecosystem services).", "keywords": ["2.

ABSTRACT Nitrogen losses by ammonia (NH3) volatilization can be reduced by appropriate irrigation management or by alternative N sources, replacing urea. The objective of this study was to evaluate the efficiency of irrigation management and N source combinations in decreasing NH3 volatilization from an Argissolo Vermelho Distr\uffc3\uffb3fico t\uffc3\uffadpico cultivated for 28 years with black oat (Avena strigosa) and maize (Zea mays), under no-tillage in the region of Depress\uffc3\uffa3o Central, Rio Grande do Sul, Brazil. The experiment was arranged in a randomized block design with split plots with three replications, where the main plots consisted of irrigation systems: no irrigation; irrigation immediately before and irrigation immediately after fertilization. The subplots were treated with different N sources: urea, urea with urease inhibitor and slow-release fertilizer, at an N rate of 180 kg ha-1, broadcast over maize, plus a control treatment without N fertilization. Ammonia volatilization was assessed using semi-open static collectors for 1, 2, 4, 6, and 10 days after N fertilization. In general, more than 90 % of total NH3-N losses occurred until three days after N fertilization, with peaks up to 15.4 kg ha-1 d-1. The irrigation was efficient to reduce NH3 losses only when applied after N fertilization. However, reductions varied according to the N fertilizer, and were higher for urea (67 %) and slightly lower for urea with urease inhibitor (50 %) and slow-release fertilizer (40 %), compared with the mean of the treatments without irrigation and irrigation before fertilization. The use of urea with urease inhibitor instead of urea was only promising under volatilization-favorable conditions (no irrigation or irrigation before N fertilization). Compared to urea, slow-release fertilizer did not reduce ammonia volatilization in any of the rainfed or irrigated treatments.

The use of controlled-release urea and urease inhibitors are possible strategies to reduce such losses and increase nitrogen use efficiency. This study aimed to evaluate nitrogen losses by ammonia volatilization from stabilized, slow and controlled release urea and its absorption by maize grown under no-till in an improved Cerrado soil. Four N sources were used: conventional urea, urea + N-(n-butyl) thiophosphoric triamide (NBPT), urea + Cu and B and urea coated by sulfur + polymers. These N sources were surface applied along the rows using three N doses of 100, 150 and 200 kg ha-1. No N was added to the control. Data were collected regarding N losses by volatilization, the N contents accumulated in the stubble and grains, and the yields of the stubble and grains. Stabilized urea and slow release urea were efficient for postponing the ammonia volatilization peaks. The urease inhibitors postponed the peaks for up to two days, reducing the accumulated volatilization by 18% when compared with common urea. Polymer sulfur coated urea resulted in a 37% reduction in ammonia volatilization. Increasing the N application rate to 200 kg ha-1 resulted in 16% greater yields and 37% greater N accumulation in the plants relative to the control. However, the stabilized and slow-release urea did not improve the N accumulation or yield. Consequently, the nitrogen use efficiency of maize was not improved relative to the use of conventional urea.

The mean annual temperature is around 15\u00b0C and the mean annual rainfall is 885 mm (Soriano and Paruelo 1992). The landscape has a treeless physiognomy and an extremely flat topography with periodic flooding during autumn\u2013spring in lowland, except in ridge areas with well-drained sandy soils (Burkart et al. 1998). The field experiment was carried out in a commercial livestock farm (35\u00b0 01\u00b4S, 57\u00b0 50\u00b4 W). The plant community is dominated by C3 and C4 grass species (see details in Druille et al. 2015). Soil is classified as a typical Natracuol (US Soil Taxonomy), characterized by having a nonsaline acid A1 horizon, and a highly alkaline saline B2 horizon (Lavado and Taboada 1988). Glyphosate was not applied at the study site before, even though glyphosate application in the late summer is a common practice in the region with a 3 l/ha dose (Rodriguez and Jacobo 2010). We applied this dose (1440 g of acid equivalent/ha) of a commercial glyphosate formulation Glacoxan\u00ae in field and greenhouse experiments with a 20 l backpack sprayer with a constant pressure of 3 bars. Pathways of single-glyphosate application To evaluate pathways of single application of glyphosate effects through living plants (1), leaf litter (2), and soil (3), we set up a litter decomposition experiment in a greenhouse. For these pathways, we used plant material that is naturally found in the field at the end of the summer when glyphosate is applied in the Flooding Pampa. At that time of the year, Paspalum dilatatum, the native dominant perennial C4 grass, can be found as a living plant and as plant litter. In turn, Lolium multiflorum, which is an introduced annual winter C3 forage grass, is only found dead as plant litter. Considering that in this grassland the vast majority of L. multiflorum plants are endophyte-infected with Epichlo\u00eb occultans (Gundel et al. 2009), in this experiment we used L. multiflorum plants associated with the endophyte. Together, for the living plant pathway we used P. dilatatum (1) and for the leaf litter pathway (2) we used litter produced by P. dilatatum and L. multiflorum with endophyte plants. Paspalum dilatatum and Lolium multiflorum plants were grown in 1 m x 1 m monoculture plots in the experimental campus of the School of Agronomy at the University of Buenos Aires. L. multiflorum plants grew from seeds with naturally high level (82%) of endophyte association (E+), and from seeds without endophyte (E-) obtained experimentally following Omacini et al. (2004). We collected fresh senesced plant litter of both species and, in the lab, sorted leaf litter from other plant organs. Then, in the P. dilatatum plots, we removed all dead plant material to applied glyphosate on living plants. After 15 days, we collected P. dilatatum plants killed by glyphosate and separated the leaf litter from other organs. We determined the total carbon (%C) and nitrogen (%N) content of all types of litter by Dumas combustion with a TruSpec elemental analyzer (LECO, St. Joseph, MI, USA) at the University of Buenos Aires. We prepared litterbags containing leaf litter from P. dilatatum plants killed by glyphosate (Plant Gx) and from naturally senesced P. dilatatum and L. multiflorum E+ plants. Litterbags were made of fiberglass mesh, which is the most common used material for litter decomposition studies (Harmon et al. 1999, Bradford et al. 2002), and that we have successfully used before (Omacini et al. 2004, Vivanco and Austin 2006, 2019).\u00a0 We used 0.5 g of each litter type in 11 cm x 9 cm litterbags with a 3 mm opening on the upper face and a 2 mm opening on the lower face. We prepared plastic containers with 1.2 kg of soil from the study site, which had not received prior glyphosate treatment. Half of the litterbags containing naturally senesced leaves were sprayed with glyphosate (Litter G+) and the other half was sprayed with water (Litter G-). Half of the soil containers were sprayed with glyphosate (Soil G+) and the other half was sprayed with water (Soil G-). We assigned litterbags (Plant Gx, Litter G+, Litter G-) to soil containers (Soil G+, Soil G-) in a factorial design and kept them moistened with regular watering (n=5). We assessed litter decomposition as litter mass loss over time. We collected litterbags after 140 and 270 days of incubation. Litterbags were dried for 48 h at 65\u00b0C; soil and debris were removed from litter and were oven-dried again for determination of dry mass. We estimated the decomposition constant k using a single exponential decay model by regressing the log of the fraction of mass remaining against time. The decomposition constant integrates the dynamics of litter mass loss over time and it is a useful parameter to compare between litter types and treatments (Wieder and Lang 1982). We used ln (Mt/Mo) = \u2013kt, where Mo is the initial dry mass, Mt is the dry mass at time t, and k is the decomposition constant (Swift et al. 1979). Linear regressions were performed by setting the intercept to zero. In the few cases when samples did not fit a significant regression, values were considered outliers and were replaced by the mean of the treatment, following the missing value procedure (Steel and Torrie 1980, Vivanco and Austin 2008). Pathways of repeated annual application of glyphosate in natural grasslands We evaluated pathways of repeated annual application of glyphosate through legacies in ecosystem properties (4) and through the enhancement of endophytic grass (5) (Fig. 1) on decomposition of leaf litter and roots in a field experiment in the Flooding Pampa. In this field experiment, we previously studied the impacts of glyphosate application on beneficial soil microorganisms (Druille et al. 2013, 2015, 2016). We established 10 plots (1.5m x 1.5 m) in an area of similar floristic composition and randomly assigned them to control (Ecosystem G-) or glyphosate application (Ecosystem G+) treatments. Every April (late summer in the southern hemisphere) for three consecutive years, we applied 3 l / ha of water to Ecosystem G- plots and 3 l / ha (1440 g acid equivalent / ha) of commercial glyphosate formulation (Glacoxan\u00ae) to Ecosystem G+ plots. We applied these treatments using a 20 l backpack sprayer with a constant pressure of 3 bars. Cattle grazing was avoided during the experiment by keeping an electric wire around the experimental area. To avoid biomass accumulation and the consequent aging of grasslands, we made a harvest of plant biomass using a lawn mower set to leave 10 cm stubble every year before application of the treatment. To evaluate pathways of repeated annual application of glyphosate, we used litter produced by plants of L. multiflorum with (E+) and without (E-) endophyte that was accumulated above and below ground (leaf and root litter). We prepared 14 cm x 14 cm litterbags made of 2 mm fiberglass mesh. We placed leaf litterbags on the ground and root litterbags buried 5 cm belowground. Considering that the place where the litter was deposited (above and belowground) can interact with the type of litter (leaf and root litter), we placed a common substrate (stem litter) litterbags on the ground and buried at 5 cm to assess the effects of the above and belowground environment. The experiment started 15 days after the third year of application of glyphosate (n = 4) and we collected litterbags at 30, 140 and 260 days. We assessed ash-free dry mass (500\u00b0C oven for 4 h) to estimate the decomposition constant k as described in Section 2.3. Together, this experiment evaluated the relative importance of pathways 4 and 5 and provides information about the effect of an aerial symbiosis on root decomposition of the host, which has not been evaluated previously. We assessed above and belowground ecosystem properties in Ecosystem G- and Ecosystem G+ plots. We measured plant cover in December (when the last litterbag pickup occurred) in 10 plots of each level of glyphosate application. For estimation of plant cover, we used the line intercept method proposed by Canfield (1941). We determined potential water evaporation at ground level by measuring the water loss of wet filter papers. We used preweighted oven-dried filter papers and wet them in the field to full water-holding capacity. Filter papers were weighed immediately before and after incubation on the ground for 1 hour at midday in May to calculate water loss. We measured two filter papers per plot in 5 replicates for each level of glyphosate application. We determined soil gravimetric water content from 10 cm depth soil cores taken in August and December (second and third litterbag harvest dates, respectively). We also determined soil organic matter content and soil potential respiration from soil cores taken in May, approximately one year after the decomposition experiment was installed in the field. Soil organic matter content was determined by total combustion in an oven at 500\u00b0C for 4 hours. We determined soil potential respiration by incubating a 15-g sample at 25\u00b0C, in a 200-ml vial with gastight septum caps. The soil was pre-incubated at water field capacity for 48 h without seedlings or any plants. CO2 production was measured 2, 4 and 7 days after a 24-h incubation period with an infrared gas analyzer (PP Systems EGM-4, Amesbury, Massachusetts, USA). We used five replicates per level of glyphosate application for soil measurements.", "keywords": ["2.

Our results showed that: (i) Higher grazing intensity resulted in lower biomass of grasses and sedges, lower root biomass, and in a change in plant community composition from palatable grasses and sedges to less palatable forbs. (ii) Increased grazing reduced the SOC content and storage with only G3 showing an SOC loss during the plant growing season. (iii) Soil organic carbon storage exhibited a highly positive correlation with the residual aboveground biomass and root biomass.

Soil microbes met the increasing respiratory demands under conditions of low C accessibility at the expenses of a reduction of the standing biomass in warmer soils. This together with the strict microbial C:N stoichiometric demands also constrained their capacity of N retention, and increased the vulnerability of soil to N losses. Our findings suggest a strong control of\u00a0microbial physiology and C:N stoichiometric needs on the retention of soil N and on the resilience of soil C stocks from high-latitudes to warming, particularly during periods of vegetation dormancy and low C inputs.", "keywords": ["0301 basic medicine", "Microbial carbon and nutrients limitation", "Microbial biomass", "TERM", "03 medical and health sciences", "FOREST SOIL", "Temperature increase", "ORGANIC-CARBON", "Substrate induced respiration", "SDG 13 - Climate Action", "TEMPERATURE SENSITIVITY", "CYCLE", "106026 Ecosystem research", "METAANALYSIS", "2.

Consequently, the use of an innovative phosphate-based treatment, aimed at bonding calcite grains by formation of hydroxyapatite at grain boundaries, has recently been proposed. In this paper, firstly a novel method for producing artificially decayed marble samples, by contact with a heating plate, is proposed. Then, some results are presented about the effectiveness and the compatibility of two different formulations of the phosphate treatment, differing in terms of concentration of the phosphate precursor (3.0 M or 0.1 M aqueous solutions of diammonium hydrogen phosphate, DAP), possible ethanol addition to the DAP solution and number of DAP solution applications (1 or 2). The results of the study point out that the new weathering method allows to obtain specimens with a gradient in microstructural and mechanical properties with thickness, just like naturally weathered samples. Both phosphate treatments were able to significantly improve marble cohesion, without causing significant changes in thermal behaviour and aesthetic appearance after treatment. The addition of small quantities of ethanol to the DAP solution seems to be a very promising method for favouring HAP formation and improving the treatment performance.", "keywords": ["0103 physical sciences", "Grain loss; Thermal ageing; Thermal diffusivity; Calcium phosphates; Ethanol", "02 engineering and technology", "ING-IND/22 Scienza e tecnologia dei materiali", "0210 nano-technology", "01 natural sciences", "6.

The objective is to estimate a premium, which is defined as a functional specified up to unknown parameters. For this purpose, the Bayesian methodology, which combines the prior knowledge about certain unknown parameters with the knowledge in the form of a random sample, has been adopted. The generalised Bregman loss function is considered. In effect, the results can be applied to numerous loss functions, including the square-error, LINEX, weighted square-error, Brown, entropy loss. Some uncertainty about a prior is assumed by a distorted band class of priors. The range of collective and Bayes premiums is calculated and posterior regret \uffce\uff93-minimax premium as a robust procedure has been implemented. Two examples are provided to illustrate the issues considered - the first one with an unknown parameter of the Poisson distribution, and the second one with unknown parameters of distributions of the number and severity of claims.Excess water can induce flooding stress resulting in yield loss, even in wetland crops such as rice (Oryza). However, traits from species of wild Oryza have already been used to improve tolerance to abiotic stress in cultivated rice. This study aimed to establish root responses to sudden soil flooding among eight wild relatives of rice with different habitat preferences benchmarked against three genotypes of O. sativa. Plants were raised hydroponically, mimicking drained or flooded soils, to assess the plasticity of adventitious roots. Traits included were apparent permeance (PA) to O2 of the outer part of the roots, radial water loss, tissue porosity, apoplastic barriers in the exodermis, and root anatomical traits. These were analysed using a plasticity index and hierarchical clustering based on principal component analysis. For example, O. brachyantha, a wetland species, possessed very low tissue porosity compared with other wetland species, whereas dryland species O. latifolia and O. granulata exhibited significantly lower plasticity compared with wetland species and clustered in their own group. Most species clustered according to growing conditions based on PA, radial water loss, root porosity, and key anatomical traits, indicating strong anatomical and physiological responses to sudden soil flooding.Emerging evidence points out that the responses of soil organic carbon (SOC) to nitrogen (N) addition differ along the soil profile, highlighting the importance of synthesizing results from different soil layers. Here, using a global meta\uffe2\uff80\uff90analysis, we found that N addition significantly enhanced topsoil (0\uffe2\uff80\uff9330\uffe2\uff80\uff89cm) SOC by 3.7% (\uffc2\uffb11.4%) in forests and grasslands. In contrast, SOC in the subsoil (30\uffe2\uff80\uff93100\uffe2\uff80\uff89cm) initially increased with N addition but decreased over time. The model selection analysis revealed that experimental duration and vegetation type are among the most important predictors across a wide range of climatic, environmental, and edaphic variables. The contrasting responses of SOC to N addition indicate the importance of considering deep soil layers, particularly for long\uffe2\uff80\uff90term continuous N deposition. Finally, the lack of depth\uffe2\uff80\uff90dependent SOC responses to N addition in experimental and modeling frameworks has likely resulted in the overestimation of changes in SOC storage under enhanced N deposition.
Intensive agriculture is dominated by monocultures of high\uffe2\uff80\uff90yielding plants that receive large applications of nitrogen (N) fertilizers to boost plant productivity. However, these systems have low N use efficiency (NUE) as fertilized plants generally take up less than half of the N applied. A large fraction of the remainder N is susceptible to be lost from the agroecosystem generating a cascade of environmental and socio\uffe2\uff80\uff90economic problems. Climate change and projected global increases in fertilizer use pose further risks to N losses and yield stability.
We review and translate concepts from ecology in natural systems to demonstrate that NUE in intensive agroecosystems can be strongly increased by fine\uffe2\uff80\uff90tuning the traits of the plant communities to the levels of N fertilization intensity.
We present key plant traits of importance for N\uffe2\uff80\uff90cycling (architectural, morphological and physiological traits, as well as symbiotic associations and exudation patterns); discuss ecological (with soil fauna and N\uffe2\uff80\uff90cycling microbial communities) and agronomic interactions of this approach; propose interdisciplinary methodologies for future research ranging from pot to global scales; and highlight possible solutions leading to an optimal balance between N fertilizer use and productivity.
Synthesis and applications. By showing the strong links between plant traits and nitrogen (N) cycling, our work opens possibilities to test ecologically informed hypotheses across gradients of soil fertility and N fertilizer management intensity, setting a research agenda for the coming years. Accordingly, the choice of plant species based on their functional traits will play a central role for the development of modern and productive agroecosystems that retain and use N more efficiently.
