Soil organic carbon (SOC) is essential for soil fertility and climate change mitigation, can be sequestered in through proper management, including straw return. However, results of studies long-term return on SOC are contradictory increasing stocks upland soils challenging. This study North China agricultural fields quantified the effects several fertilizer treatments storage changes crop yields, considering different cropping duration periods, types, systems to establish relationships...
Core Ideas Straw returned twice each year (WC‐MC and WH‐MC) significantly enhanced SOC DOC. Return of both wheat maize chopped straw had highest β‐1,4‐xylosidase, invertase, Alphaproteobacteria Gammaproteobacteria . Retention high stubble return β‐1,4‐glucosidase, cellobiohydrolase, Acidobacteria Planctomycetes Amount complexity added led to differences in C, enzyme activity, microbial composition. High crushed improved yields bacterial richness, but less C sequestration. Little is known...
Decomposition of maize straw incorporated into soil with various nitrogen amended carbon to (C/N) ratios under a range moisture was studied through laboratory incubation trial. The experiment set up simulate the most suitable C/N ratio for (C) decomposition and sequestering in soil. purpose this study determine organic C by measuring CO2 evolution using alkali traps. Maize mixed clay loam topsoil supplied four initial rates (40, 80, 160, 320 mg N/0.5 g C) (NH4)2SO4, adjust its 40, 18 9....
Soil fertility can be improved by effectively utilizing agricultural waste. Straw supply energy and wood ash adds nutrients to improve soil quality. However, few kinds of research have investigated the effect straw on carbon sequestration bacterial population, particularly in calcareous soils. The main goal this current study was quantify impact a combination indicators described above using stable δ13C isotope analyses applying wheat under long-term C4 crop rotation. incubation experiment...
Abstract The return of organic materials to cultivated fields improve soil quality and sequester carbon are widely studied, but the effects combining different types material on microbial diversity community structure poorly understood, particularly in alkaline soils. An incubation experiment was performed study incorporating two straw‐derived (fresh straw semi‐decomposed straw) alone or combination with wood ash. content treated significantly higher than that no addition, there significant...
A two-year field experiment was conducted to investigate the response of soil carbon sequestration, crop yield and economic benefit rates NPK application straw returning under rice–wheat rotation from 2015 2017. The included five treatments: without (SN+NPK), with (S+NPK), decayed (SD+NPK), 15% reduction plus (SD+85%NPK) (SD+70%NPK). Compared SN+NPK, total organic (TOC) active (LOC) in 0–15 cm depth increased by 3.62%–25.07% 23.01%–46.79% treatments different returned application,...
Straw return is widely applied in China to achieve sustainable grain production. However, inappropriate farm practices can increase greenhouse gas (GHG) emissions and reduce soil organic carbon (SOC) sequestration, thereby increasing the footprint (CFP) affecting fertility climate change. A 10-year experiment was conducted evaluate quantify effects of straw management on SOC, crop yield, CFP under a winter wheat–summer maize rotation Guanzhong Plain. The involved seven straw-return modes,...
