This study assessed the effects of integrating the legume <i>Stylosanthes guianensis</i> (stylo) into a conservation agriculture (CA) rotation on rice N use efficiency (NUE), and biomass productivity in Madagascar's Midwest Highlands. A factorial field experiment tested soil tillage, stylo biomass management (retention, removal, incorporation), and N fertilizer types (none, farmyard manure, mineral fertilizer), using ¹⁵N isotope labelling techniques, which allowed us to quantify N sources and recovery pathways with high resolution. Mineral fertilizer resulted in the highest grain yield (429 g DM m^-2), N uptake (6.1 g N m^-2), and ¹⁵N recovery (52%), surpassing global NUE benchmarks. In the absence of fertilizer, rotation with stylo increased grain yield by 53% and N uptake by 43% compared to continuous rice (189 g DM m^-2; 2.3 g N m^-2), reflecting strong biological and structural legacy effects. Although stylo mulch had a high C:N ratio and contributed minimally to direct N uptake, it improved soil moisture and likely promoted conditions favourable to N mineralization. Tillage effects on N uptake and yield were negligible. These findings demonstrate that legume integration under CA can improve N cycling, enhance fertilizer N recovery, and significantly increase NUE and yield resilience in smallholder systems. Future strategies should explore how partitioning legume biomass between soil cover and fodder affects nutrient flows, and whether livestock-mediated recycling can help close N loops in mixed farming systems.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10705-025-10458-w.</p>","PeriodicalId":19336,"journal":{"name":"Nutrient Cycling in Agroecosystems","volume":"132 1","pages":"5"},"PeriodicalIF":2.7,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12685974/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145724856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Large nitrous oxide emissions from arable soils after crop harvests prior to sowing.","authors":"Regine Maier, Lukas Hörtnagl, Nina Buchmann","doi":"10.1007/s10705-024-10395-0","DOIUrl":"10.1007/s10705-024-10395-0","url":null,"abstract":"<p><p>Global agriculture is the largest anthropogenic source for nitrous oxide (N₂O) emissions. During crop rotations, periods with arable soils without crops, thereafter called \"bare soils\" are often impossible to avoid after the crop is harvested, prior to sowing of the next crop. However, such periods are underrepresented in studies focussing on N₂O emissions. Here, we present continuous, high-temporal-resolution N₂O fluxes during bare soil periods after four major crops, using the eddy-covariance technique at two sites in Switzerland. Overall, periods with bare soil were net sources for N₂O as well as for carbon dioxide (CO₂) and methane (CH₄). Daily average sums of N₂O emissions varied between 10 ± 2 and 38 ± 5 g N₂O-N ha^-1 d^-1 after the respective rapeseed, winter wheat, pea, and maize harvests. While CO₂ emissions contributed 86-96% to the total GHG budgets, N₂O fluxes accounted for 2% after pea, but for 10-12% after rapeseed, winter wheat, and maize. In contrast, CH₄ fluxes were negligible (< 2%). N₂O fluxes during bare soil periods increased for all cropland sites with increasing water-filled pore space, particularly at high soil temperatures. Thus, our study emphasizes the significance of avoiding bare soil periods to mitigate N₂O emissions from croplands.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10705-024-10395-0.</p>","PeriodicalId":19336,"journal":{"name":"Nutrient Cycling in Agroecosystems","volume":"130 2","pages":"161-175"},"PeriodicalIF":2.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11950146/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143753844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
