Straw return and straw-derived biochar are promising practices for improving soil physicochemical properties crop production. However, the integrated effects of a single application on moisture, heat, salinity transport, their regulation mechanism water use efficiency (WUE) in salt-affected soils still understood deeply. Four amendments were used: control without any additives (CK), direct 10 t ha -1 straw (BJ), treatments 15 (B15), 30 (B30). Application generally increased moisture content during whole growth periods. Temperature top cm by 0.97°Cfor B30 1.08°C BJ when averaged two growing seasons.

Understanding the variability in mechanical and hydrological soil characteristics resulting from diverse tillage residue management practices is essential for evaluating adoption of conservation strategies to preserve soil’s physical well-being. Zero-tillage techniques combined with retention or incorporation have gained widespread recognition their capacity conserve water resources, reduce energy consumption, enhance quality environmental sustainability. Nevertheless, choice options may vary depending on geographical locations specific conditions. To assess impacts four distinct approaches, a two-year experiment (2020–2021 2021–2022) was conducted: T1: conventional followed by wheat sowing after removal rice straw (CT-RS); T2: zero using Happy Seeder while retaining (ZT+RS); T3: reversible mouldboard plough (CT+RS); T4: minimum Super (MT+RS); effects were recorded properties. Our findings indicate that (T2) had positive influence various attributes. Notably, significant differences observed among options, particularly terms bulk density T1 exhibiting highest values lowest being T2, whereas penetration resistance T3 compared T1. In case T3, sandy loam clay soils measured saturated hydraulic conductivity values, measuring 5.08 4.57 cm h−1 4.07 3.73 h−1, respectively. Furthermore, T2 (zero retention) demonstrated mean weight diameter (MWD) maximum stable aggregate. These results collectively underscore adopting structure quality, concerning

In the dryland area of Loess Plateau in northwest China, long-term excessive fertilization has led to soil compaction and nutrient loss, which turn limits crop yield productivity. To address this issue, we conducted experiments using environmentally friendly organic fertilizer bacterium fertilizer. Our goal was investigate effects additional inputs on water migration, root architecture, formation. We implemented six different strategies, namely: N m (mulching, 30 kg/ha), NPK 1m 60 kg/ha; P K 2m 90 45 Om 2 t/ha), Bm 10 (N no mulching). The results revealed that addition (NPK ) had a positive impact soybean system development. Compared with other treatments, it significantly increased total length, surface area, length density by 25.96% ~ 94.89%, -19.63% 36.28%, 9.36% 28.84%, respectively.
