Nitrogen Transformation Mechanisms and Compost Quality Assessment in Sustainable Mesophilic Aerobic Composting of Agricultural Waste

Sustainability, Journal Year: 2025, Volume and Issue: 17(2), P. 575 - 575

Published: Jan. 13, 2025

This study examines nitrogen transformation mechanisms and compost quality in mesophilic aerobic composting of wheat straw, utilizing cow manure as a co-substrate to promote sustainable agricultural waste management. Two systems were established: group A (control) B (10% addition by wet weight). The accelerated early organic matter decomposition increased total retention B. Nitrogen losses occurred primarily via ammonia volatilization during the initial final stages, while functional gene analysis revealed enhanced ammonification nitrification both systems. Microbial community showed that promoted nitrogen-fixing bacteria phase fungi associated with complex degradation later stages. These findings underscore potential enhance maturity, improve efficiency, support development practices contribute resource conservation.

Macrogenomics-Based Analysis of the Effects of Intercropped Soybean Photosynthetic Characteristics and Nitrogen-Assimilating Enzyme Activities on Yield at Different Nitrogen Levels

Microorganisms, Journal Year: 2024, Volume and Issue: 12(6), P. 1220 - 1220

Published: June 18, 2024

Currently, China’s soybean self-sufficiency rate is only 15%, highlighting the crisis and supply chain risks that pose a major threat to food security. Thus, it has become imperative step up efforts boost production capacity while promoting green sustainable development of regional farmland ecosystems. In this context, present study comprehensively investigated effects intercropping nitrogen application on yield, as well changes in gradients generated by different levels application. Based six consecutive years maize–soybean planting patterns, inter-root soils soybeans were collected at flowering stage evaluated for soil content, nitrogen-assimilating enzyme activities, microbial community composition soybean, which correlated with clarify main pathways modes effects. The N2 level (80 kg·ha−1) was favourable higher yield. comparison monocropping, reduced yield 9.65–13.01%, photosynthetic characteristics 1.33–7.31%, plant activities 8.08–32.01% same N Likewise, urease catalase 9.22 1.80%, content declined an average 6.38%. Gemmatimonas Bradyrhizobium enrichment significantly increased characteristics, Candidatus_Udaeobacter Candidatus_Solibacte enrichment. results provide theoretical basis further optimising intercropping, crucial enhancing agricultural structure improving overall capacity.

Maize/soybean intercropping with nitrogen supply levels increases maize yield and nitrogen uptake by influencing the rhizosphere bacterial diversity of soil

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: Sept. 3, 2024

Introduction Intercropping practices play a crucial role in enhancing and maintaining the biodiversity resiliency of agroecosystems, as well promoting stable high crop yields. Yet relationships between soil nitrogen, microbes, yield maize cultivated under maize/soybean intercropping systems remain unclear. Methods To fill that knowledge gap, here we collected rhizosphere at staminate stage after 6 consecutive years intercropping, to investigate how nitrogen application rates affected utilization by crops microbial community composition function. We also examined correlations those responses with yields, clarify main ways is enhanced via nitrogenous fertilizer gradient changes generated different rates. Results The amount applied was 240 kg N ha -1 best for obtaining led greatest nitrogen-use efficiency bacterial diversity. Under same rate, increased 31.17% (total, ammonium nitrate nitrogen) 14.53%, on average, comparison monocropping. enrichment Gemmatimonas Bradyrhizobium significantly content, greater relative abundance Sphingomonas yield, whereas Candidatus_Udaeobacter decreased it. benefits mainly arise from augmenting beneficial microorganisms use plants. Discussion This study’s findings are key importance bolster stability agro-ecosystems, guide scientific rational fertilizers, provide sound theoretical basis achieving optimal management intensive crop-planting patterns green sustainable development.
