Ammonia (NH3) volatilization caused by urea application has negative implications for human health, environmental quality, and the value of nitrogen fertilizers. It remains to be investigated how management strategies should adopted not only reduce NH3 but also improve use efficiency (NUE) in agriculture industry at present. Hence, a two-year field trial, including subplots, was conducted simultaneously evaluate effects mulching treatments (NM: non-mulching; SM: straw mulching) different fertilizer (U: urea; U + NBPT: plus 1% N-(n-butyl) thiophosphoric triamide; CRU: mixture controlled-release 3:7 ratio; OF: commercial organic ratio) on volatilization, crop production, NUE an oilseed rape–maize rotation system sloping farmland purple soil southwestern China between 2021 2023. Compared with NM U, losses under NBPT, CRU, OF decreased, average, 64.13%, 17.39%, 15.09% during rape growing season 64.01%, 11.67%, 10.13% maize season, respectively. An average increase 35.65% straw-mulching treatment recorded while this parameter showed 10.69%, comparison U. With combination fertilizer, contrastingly, reduction achieved SM treatments. When compared difference significant season.

As extreme rainfall events become more frequent, leading to increased waterlogging hazards, it is crucial explore various drainage methods that can alleviate the adverse effects of on crop growth, thus addressing challenges related global food security. Field experiments were carried out evaluate impacts different technologies mitigation, rice dry matter accumulation, and yield. The experimental setup included varying straw blind ditch spacings (2, 3, 4, 5 m) subsurface pipe (6, 9, 12 m), with surface serving as control (CK). findings revealed that, in comparison treatments, treatments enhanced volume by 15.1%. Regarding groundwater levels soil moisture, moisture 0–90 cm layer under 11.3% 6.1% lower than those CK well 22.0% 23.9% respectively. Subsurface led significant improvements yield, increasing yield 8.0% 6.0% compared CK. Rice yields initially before decreasing burial spacing reduced. S3 treatment resulted increases 14.4%, 8.6%, 10.7% over S2, S4, S5 G9 produced 3.6% 10.4% higher G6 G12 treatments. highest 7.501 Mg·ha−1, was achieved a 3 m. Compared S4 per hectare for 0.592 Mg 0.726 Mg, while input cost CNY 3038 4560, Path analysis indicated root biomass made largest direct contribution (0.517) increase contributed regulation reducing leaf stem biomass, which enabled produce optimal These results provide scientific basis agricultural waterlogged areas.

Straw return is an effective agricultural measure that influences the ecological environment. In context of global climate change and need for sustainable development, it essential to explore how straw methods affect This study conducted a two-year field experiment comparing different treatments: no (CK), directly (SR), returned in deep ditches (ISR). The results showed SR treatment increased soil dissolved organic carbon (DOC) (21.7~25.8%) nitrogen (DON) (8.5~43.8%) compared CK. ISR significantly enhanced DOC (13.1~33.0%) DON (14.2~50.8%). Both treatments also improved maize growth indicators, such as leaf area index (LAI), stem biomass, grain biomass. terms environmental effects, reduced N2O emissions lowered footprint (CF) water (WF). Specifically, yield-scale (CFy) (WFy) were by 12.0% 9.1%, respectively, 2023. Correlation analysis revealed key factors these benefits. Furthermore, reduction WF CF was closely linked SWC higher biomass all organs. Therefore, we demonstrated not only promotes accumulation but effectively mitigates consumption on farmland. It may be related boosting levels. Overall, method holds promise supporting farming practices.
