Soil texture affects rice nutrient uptake and yield formation by influencing soil structure, microbial activity, supply capacity. Analyzing the relationship between texture, content, agronomic traits is of great significance for precise efficient fertilizer application. The tillage layer (0–20 cm) 31 paddy fields in China’s main rice-producing areas was collected to perform pot experiments, characteristics, physicochemical properties, microbial-related indicators, were measured analyzed. results showed that these soils could be classified into four types texture: loamy sandy soil, loam silty soil. Analysis variance available nitrogen (AN), potassium (AK), phosphorus (AP) contents highest loam, silty, soils, respectively, silt had CEC. Principal component analysis (PCA) also properties can distinguished a certain extent according types. For parameters organic matter (OM), total (TN), AN, ammonium (NH4+-N), carbon (MBC) positively correlated with clay AK status significantly related pH. Mantel’s test revealed significant correlations N, P, K status, dry accumulation, yield, MBC, pH, parameters. Structural equation modeling (SEM) indicated sand affected nutrients regulating while influence affecting mineralization thus absorption rice. Overall, production, fine higher content facilitates activity microbes, resulting more nutrients, which benefits accumulation nutrients. Furthermore, promotes distribution panicle, thereby promoting formation.

Intensive and large-scale drip irrigation plays a crucial role in ensuring cotton production Northwest China. However, significant differences have occurred at times within systems, quantitative information on the importance interactions of factors related to growth constraints is scarce. In 2018–2019, we monitored six possible (irrigation depth, soil texture, salt, moisture, inorganic nitrogen organic matter) associated with management seed yields collective system (CDIS, composed several subsystems (DISs)) southern Xinjiang assess different identify main constraints. 2023, other more refined field trials were conducted further evaluate influencing mechanism crop one typical DIS selected CDIS. The results revealed large yield CDIS; although average was good (2018: 8051 kg ha−1, 2019: 6617 ha−1). Excessive depths (>500 mm) coarse texture (sand content > 70%) identified as constraints, affecting than 45% plant area CDIS based boundary line analysis (a method study responses between variables) from DISs that two directly affected moisture root zone, which reduced effectiveness fertilization under irrigation. Structural Equation Model (used causal relationships among multiple both depth indirectly affect by N uptake critical resisting decline caused An optimized schedule, improved uniformity network adjusted strategies could be used for site-specific address due improve water fertilizer use efficiency management.

Abstract Over the past century, inefficient use of reactive nitrogen (N r ) has raised concerns regarding global food production and planetary sustainability. This study investigates (N) losses in tomato near Kabul, Afghanistan, aiming to improve efficiency (NUE) for enhanced security environmental protection. Three fertilizer treatments were tested: (A) animal manure + ¼ dose chemical fertilizer, (B) night soil (C) full with sub-treatments varying N application (25% less, 25% excess, farmers’ practice). A no-fertilizer control treatment was included. Nitrogen through ammonia emissions nitrate–N leaching monitored, while balances NUE calculated. The findings revealed that decreased by 33% 2 30% B 3 compared surface application. However, peaked at 145 kg ha −1 128 , positive observed across treatments, highest being 300 A. ranged from (A B) 55% (control), highlighting widespread overapplication Afghan agriculture. demonstrates efficient management practices can reduce maintaining yield, offering a novel pathway toward sustainable farming region.

The high-input production mode of rice monoculture (RM) has caused severe soil degradation and biodiversity loss, necessitating a transition toward more sustainable practices. traditional rice-fish co-culture (RF) may provide valuable insights for this situation. However, it remains elusive how long-term RF system influences microbial community structure, enzyme activities, carbon (C) sequestration. Here, study was conducted at two representative areas in Lianshan Zhuang Yao Autonomous County. At Shatian (P1), three treatments included (RM1) 2-year 5-year (RF2, RF5). Gaoliao (P2), the experimental (RM2) 15 30 years (RF15, RF30). We collected surface layer (0–20 cm) soils. Then, we analyzed chemical properties, phospholipid fatty acids (PLFA), activities to investigate effects their variation on C results showed that significantly increased organic (SOC) content. Specifically, RF2 RF5 promoted SOC content by 4.82% 13.60% compared with RM1 treatment P1, respectively; RF15 RF30 23.41% 31.93% RM2 P2, respectively. Additionally, biomass comparison treatment, as did including total PLFA gram-positive bacteria (G+), gram-negative (G−), actinomycetes, fungi, bacteria. Activities β-glucosidase, cellobiohydrolase, β-1,4-N-acetylglucosaminidase, urease treatments. piecewise SEM indicated changes ratio fungi were related dissolved (DOC) N (TN) under different durations, which are key indicators affecting Overall, storage increases structure drive sequestration RF, provides scientific significance practical value promoting sustainability agricultural ecosystems, enhancing potential sink, addressing global climate change.

In the context of global climate change, it is crucial to adopt ecologically sound production practices promote sustainable agricultural development. Combined rice–fish, rice–crab, and Zizania latifolia (ZL)–shelduck modes are increasingly advocated by scholars because complex farmland landscapes environmentally friendly nutrient cycles associated with these modes. this study, a comprehensive evaluation ecological–economic benefits combined planting–breeding system in Jinyun, Zhejiang, China, was conducted via life cycle assessment (LCA) cost–benefit analysis on basis literature review field research data. The following results were obtained. (1) single-season total carbon footprint for ZL–shelduck mode 4062.19 kg CO 2 eq/ha, whereas 4553.32 eq/ha ZL monoculture mode. Compared those mode, emissions decreased 10.79%, inputs identified as primary source both (2) net ecological economic 102,482.26 yuan/ha 70,423.60 yuan/ha, respectively. significantly increased 45.52% Notably, sale shelduck products reductions labor costs important factors leading income gap between two types This study not only provides quantitative different but also serves an reference introduction relevant compensation policies promotion win–win future.
