Residue Management and Nutrient Stoichiometry Control Greenhouse Gas and Global Warming Potential Responses in Alfisols

Sustainability, Journal Year: 2024, Volume and Issue: 16(10), P. 3997 - 3997

Published: May 10, 2024

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, Journal Year: 2025, Volume and Issue: 31(4)

Published: April 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.

Core Soil Microorganisms and Abiotic Properties as Key Mechanisms of Complementary Nanoscale Zerovalent Iron and Nitrification Inhibitors in Decreasing Paclobutrazol Residues and Nitrous Oxide Emissions

Journal of Agricultural and Food Chemistry, Journal Year: 2024, Volume and Issue: 72(14), P. 7672 - 7683

Published: March 26, 2024

Agrochemical residues and nitrous oxide (N2O) emissions have caused considerable threats to agricultural soil ecology. Nanoscale zerovalent iron (nZVI) nitrification inhibitors might be complementary each other diminish agrochemical N2O enhance bacterial community diversities. Compared the control, nZVI application declined paclobutrazol by 5.9% but also decreased co-occurrence network node. Combined Dicyandiamide applications significantly emission rates promoted Shannon diversity of community. The increased pH, ammonium nitrogen, Actinobacteriota could promote dissipation. generated double-edged sword effects positively decreasing negatively influencing multifunctionalities. in diminishing promoting diversities simultaneously.
