Although crop residue returns are extensively practiced in agriculture, large uncertainties remain about greenhouse gas (GHG) emissions and global warming potential (GWP) responses to return (RR) rates under different placements nutrient supplements. We conducted a laboratory mesocosm experiment Alfisol central India investigate the of soil GHG (CO2, N2O, CH4) four wheat RR (R0: no residue; R5: 5 Mg/ha; R10: 10 R15: 15 Mg/ha) two (surface [Rsur] incorporated [Rinc]) three supplement levels (NSLs) (NS0: nutrients, NS1: nutrients (N P) added balance stoichiometry C:N:P achieve 30% humification at t/ha, NS2: 3 × NS1). The results demonstrated significant (p < 0.05) interaction effect NSL placement on N2O emission. However, CH4 GWP rate were independent NSL. fluxes ranged from −2.3 µg N2O-N kg−1 (R5 NS0 Rsur) 43.8 (R10 NS2 Rinc). A non-linear quadratic model yielded best fit for with (R2 ranging 0.55 0.99) all NSLs placements. Co-applying Mg/ha NS1 reduced (cf. R0 increasing 12:1 (C:N) 50:1 (C:P), which increased R0) across Averaged placements, order effects (µg C soil) was R10 (5.5) > R5 (3.8) R15 (2.6) (1.6). Our linear response total R0, 201.4 1563.6 mg CO2 eq soil. In conclusion, quadratic/linear GHGs underscore need optimize supplements reduce while ensuring optimal health productivity.

Additive Effects of Multiple Global Change Drivers on Terrestrial Nitrogen Cycling Worldwide

Global Change Biology, Год журнала: 2025, Номер 31(4)

Опубликована: Апрель 1, 2025

ABSTRACT Global change has dramatically altered the Earth's biogeochemical cycles. However, interactive effects of multiple global factors (GCFs) on terrestrial nitrogen (N) cycling worldwide remain unclear, limiting ability to predict how future will affect N cycle. We conducted a meta‐analysis 108 published articles evaluate main and elevated CO 2 , addition, warming, precipitation soil pools (NH 4 + NO 3 − organic N) transformation rates (N mineralization, nitrification, denitrification) across ecosystems. Results showed that single GCFs impacted cycle in different directions magnitudes, with addition increased having strongest positive rates, respectively. Moreover, were generally enhanced when combined other GCFs. Although interactions commonly additive (66.2%–83.3%), both synergistic (10.5%–15.1%) antagonistic (2.8%–18.9%) also observed. The types treatment ecosystem, geographic location, climate all regulated responses some degree, while only ecosystem significantly affected response These findings emphasize importance considering among highlight necessity incorporating these into Earth system models for accurate predictions changes.

Future climate change impacts on grain yield and agricultural greenhouse-gas emissions under different cropping systems in the North China Plain

Crop and Pasture Science, Год журнала: 2025, Номер 76(6)

Опубликована: Июнь 2, 2025

Context The winter wheat–summer maize double-cropping system with high input and output in the North China Plain (NCP) is primary source of greenhouse-gas (GHG) emissions. As climate warms, NCP faces challenges improving agricultural productivity, while reducing carbon footprint. Aims This research aims to explore an optimal cropping that achieves a balance between yield reduced environmental impact, promoting sustainable development. Methods On basis data from 27 global models (GCMs), we evaluated impacts future climatic change on GHG emissions five systems by using Agricultural Production System Simulator Model (APSIM). included (1Y2MS0, 1-year cycle), maize-fallow without/with straw mulching–early (2Y3MS0/2Y3MS1, 2-year early mulching (1Y1MS0/1Y1MS1, cycle). Key results Future was beneficial for wheat yields all under most scenarios. were projected increase future. However, compared conventional intensive 1Y2MS0, adjustment could decrease indirect input, thereby 21.6–46.0%. Straw during fallow period might slightly N2O but enhance soil sequestration. Conclusions We suggested 2Y3MS1 planting grain Implications study can inform cleaner production developments reduce footprint regional multi-crop systems.
