We need to understand such recent trends, their driving forces, and their effectiveness to harness or leverage them for regional food security and sustainable development. To gain this understanding, we analyzed changes in fertility-related agronomic practices in six representative rice-based production systems of Southeast Asia (three favorable and three marginal sites). We implemented a diachronic survey (comparing the years 2000 and 2018) combined with field sampling and measurements in 1024 rice-producing households and, where applicable, in both dry and wet seasons (3638 complete data sets). We observed that soil fertility management followed similar trends across sites. However, the timing and the extent of changes were location specific, and differed primarily by the favorability/marginality of the site, and farmers’ capability to adopt technological innovations. The irrigated rice double cropping benefitted most from recent technology innovations (hybrid seeds, farm machinery), accelerating the adoption of improved fertility management practices to an aggregated level of up to 75% (mean across the six soil fertility-related management practices) at favorable sites. Most prominent were multiple splitting of mineral N and the application of mineral fertilizers other than N (P, K, Zn). At marginal sites, aggregate changes toward intensification were rather low with 35–55%, and farmers tended to intensify the non-rice component in the system by applying mineral fertilizers and organic amendments to dry season upland crops. A balanced use of nutrients will require the targeting of options to specific extrapolation domains (social-ecological target environments) based on site attributes and farmers’ resource endowment.</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"43 6","pages":""},"PeriodicalIF":7.3,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13593-023-00932-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138431632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crop residues with distinct ecological stoichiometry from inorganic fertilizers can help balance soil ecological stoichiometry and thus increase soil organic matter accumulation. The combined use of inorganic fertilizers and crop residues is expected to alleviate the metabolic limitations of organisms and enhance soil C, N, and P sequestration, hence increasing grain yields. However, the effects of this practice on soil C, N, and P stocks and grain yield remain unclear. In this study, we conducted a meta-analysis of 806 paired data to investigate the impact of crop residue return combined with inorganic fertilizer on soil and grain yield across different land uses (paddy, upland, paddy-upland rotation) and soil profiles (0–60 cm). Our findings indicate that crop residue return significantly enhances soil C (8–13%) stocks across all soil layers, particularly in the topsoil (0–20 cm). Soil N (9%) and P (5%) stocks also increase significantly in the topsoil. In uplands, crop residue return can mitigate soil acidification and increase grain yield (by 7%). Moreover, the soil C and N stocks increase depending on the initial soil pH, C and N levels, and C:N ratio. In contrast, the soil P stock increase depends on rainfall, while the grain yield increase is closely linked to the soil texture and fertilizer rate. Our study highlights that crop residue return can increase topsoil C, N, and P stocks, which can benefit crop growth and environmental mitigation efforts. Furthermore, this practice can increase C stocks in deeper soil horizons (below 20 cm), providing a long-term solution to mitigate climate change.</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"43 6","pages":""},"PeriodicalIF":7.3,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138138533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study reveals various types of interactions between animal enterprises. Complementarities were observed between ruminant and monogastric enterprises, particularly fertilizer transfer from monogastric manure to grasslands.

Eleven out of the 95 farms combined above-average production efficiency, on-farm processing, and the majority of sales in short distribution channels. Their labor productivity converged toward 22 livestock units per annual work unit, regardless of the number of workers. Combining farm structure; livestock production efficiency; social elements, such as the workforce; and sales management led us to distinguish four types of farms: (i) small and very autonomous grassland farms with on-farm processing and short distribution channels; (ii) dairy farms associated with a high-density pig or poultry enterprise, whose feed purchase contributes to high rates of cattle feeding self-sufficiency and stocking rate; (iii) large farms with an extensive, grassland beef enterprise associated with either sheep or monogastrics; and (iv) dairy sheep associated with goat or beef cattle on rangelands, with high added-value products enhancing salaries. This study highlights for the first time the diversity of organic multispecies livestock farms and how consistent patterns of interactions among farm structure, livestock management, sales management, and workforce management shape them.

We conducted a Morris global sensitivity analysis on an evaluated agricultural system model (APSIM) across 132 years of climate data to identify important drivers of PUE in a subtropical dryland cropping system. We selected soil, crop, and management parameters to understand their influence on yield, biomass, and grain P export as measures of PUE in a subtropical wheat crop. We then examined three P fertility scenarios ranging from low to high (10, 40, 70 mg available P kg⁻¹ at 0–10 cm, with subsoils to 180 cm at 9–10 mg available P kg⁻¹) resulting in 1,782,000 simulations. In scenarios with medium or high P fertility and higher in-crop rainfall (&gt; 200 mm), nitrogen (N) fertiliser was the most important driver for increasing yield and associated PUE. At low P fertility and lower in-crop rainfall (&lt; 200 mm), P fertiliser and P sorption isotherm parameters were the most important drivers. This highlighted potential constraints to PUE analysis in the region if rainfall data is not available, and to modelling activities if P isotherm data is not available. Our study is the first to use a Morris global sensitivity analysis method for defining the influence of N and P fertiliser, and in-crop rainfall, as short-term (year–year) drivers of PUE. This method may be adapted to investigate emerging challenges in increasing PUE in other agricultural systems, but future research should include interactions with deep P banding, the effects of climate change, and demonstrate drivers over the longer-term (5–10 years).</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"43 6","pages":""},"PeriodicalIF":7.3,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92158490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most of these agricultural energy studies have focused only on external inputs at the crop level, concealing the important role of internal biomass flows that livestock and forestry recirculate within agroecosystems. Here, we synthesize the results of 82 farm systems in North America and Europe from 1830 to 2012 that for the first time show the changing energy profiles of agroecosystems, including livestock and forestry, with a multi-EROI approach that accounts for the energy returns on external inputs, on internal biomass reuses, and on all inputs invested. With this historical circular bioeconomic approach, we found a general trend towards much lower external returns, little or no increases in internal returns, and almost no improvement in total returns. This “energy trap” was driven by shifts towards a growing dependence of crop production on fossil-fueled external inputs, much more intensive livestock production based on feed grains, less forestry, and a structural disintegration of agroecosystem components by increasingly linear industrial farm managements. We conclude that overcoming the energy trap requires nature-based solutions to reduce current dependence on fossil-fueled external industrial inputs and increase the circularity and complexity of agroecosystems to provide healthier diets with less animal products.</p></div>","PeriodicalId":7721,"journal":{"name":"Agronomy for Sustainable Development","volume":"43 6","pages":""},"PeriodicalIF":7.3,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13593-023-00925-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71516740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to investigate this paradox and provide solutions, we set out to examine the perceived constraints to CA implementation among farmers and stakeholders. Our approach is based on systems analysis of Mediterranean grain production systems, considering plant and livestock production, as well as sustainability and social-ecological interactions.

Such an approach should be based on site-specific bio-physical and sociocultural considerations and augmented with principles of agroecology. Our review of perceived constraints allows us to suggest five pathways that could promote CA adoption in the Mediterranean across two main areas: (i) introduction of flexible, context-specific technical solutions and (ii) change of social perceptions and literacy on soil. Our five pathways aim to enhance farmers’ resilience to challenges of climate and market shocks, while integrating agroecological principles that enhance ecosystem multifunctionality.

Against this backdrop, the adoption of solutions based on the reproductive behavioral ecology of pests is a subject of prominent (major) interest for the coming decades. Crop pests and, more specifically, disease vectors use sensory cues throughout their life cycle for many fundamental behaviors and in particular for mating, the critical step in population growth. In particular, a large proportion of arthropod crop pests rely on chemical and/or vibroacoustic communication to mate. Several thousand sex pheromones have been identified in insects, most of which can be used either as synthetic baits to trap pests or as behavioral modifiers (e.g., pheromone-mediated mating disruption). Applied biotremology is also emerging as a new discipline for sustainable pest control. Field experiments on vibratotional mating disruption against grapevine leafhoppers are currently ongoing, with promising results.
