Abstract Biochar application can alleviate the adverse effects of saline-alkali stress on crops. However, long-term one-off biochar soil physicochemical properties, salt concentration, nutrient availability, enzyme activities, and rice yield under highly paddy soils remain unclear. Here, a 6-year field study was conducted in using two nitrogen levels (0 225 kg ha −1 ) four rates [0 (T0), 1.5% (T1.5), 3.0% (T3.0), 4.5% (T4.5) biochar, w/w]. The results showed that compared with T0, bulk...
The purpose of this study was to clarify the effects biochar on diversity bacteria and fungi in rice root zone reveal changes soil microbial community structure after application provide a scientific basis for improvement albic soil. Rice corn stalk were mixed with pot experiment. Soil samples collected at maturity stage, nutrients determined, genomic DNA extracted. library established using polymerase chain reaction (PCR) amplification. abundance, index, bacterial 16SrRNA gene V3 + V4...
Abstract Return of crop straw and its biochar to the agricultural field decreases pressure on phosphorus (P) resources reduces leaching P runoff. We conducted a 5‐year trial from 2013 2017 study capability maize retain soil P, which was quantified by investigating distribution fractions in profile (0–100 cm) aggregates different grain sizes. The impact treatments with nitrogen‐phosphorus‐potassium (NPK) fertiliser alone or combined were examined. found that increased aggregate stability,...
Soil microbial organisms are conducive to SOC sequestration. However, little attention has been given the contributions of living MBC and necromass carbon pool under biochar straw amendments. The aims study were explore (1) effects maize on MBC, POC, MAOC, DOC carbon; (2) contribution pool; (3) relationships among soil community structure, other fractions application for nine consecutive years. Three treatments studied: CK (applied chemical fertilizer only), BC (biochar applied annually at a...
The effects of the co-application nitrogen (N) fertilizers and different biochar materials on rice yields GWP paddy fields in northern China remain unclear. Herein, we conducted a 2-year field experiment to evaluate effect combined N fertilizer (three levels: N0, 0 kg ha−1; N1, 210 N2, 168 ha−1) application (two BM, maize straw biochar; BR, rice-husk biochar) yield greenhouse gas (GHG) emissions. BR BM significantly increased yield, particular when applied with N2 fertilizer, by 4.89% 4.48%,...
Biochar has been shown to influence soil microbial communities in terms of their abundance and diversity. However, the relationship among abundance, structure C metabolic traits is not well studied under biochar application. Here it was hypothesized that addition with intrinsic properties (i.e., porous structure) could affect proliferation culturable microbes genetic bacterial communities. In meantime, presence available organic carbon may utilization capacities community Biolog Eco-plates....
Turning maize straw into biochar is useful for improving soil fertility and mitigating climate change. However, the difference between straw-derived on aggregate associated humic substances has not been sufficiently studied in brown earth soil. The objective of this study was to investigate how different management practices affect aggregate-associated field. As such, an eight-year (2013–2020) conducted Northeast China. Three treatments were applied: 1) CK, which only chemical fertilizer...
Biochar is a potential amendment for the remediation of Cd-contaminated soils. Although immobilization effect biochar on soil Cd has been studied under indoor laboratory conditions, rice uptake and fractions field conditions still poorly understood. Here, content different organs in were characterized three years after application amounts (0, 7.5, 15, 30 t ha−1, 3 ha−1 year−1). The brown rice, husk, leaf, stem sheath, root treatment could be maximally reduced by up to 26.25%, 20.16%, 20.74%,...
