Identification and Evaluation of the Main Constraints on Cotton Production Within a Collective Drip Irrigation System in Southern Xinjiang, China

Agronomy, Journal Year: 2025, Volume and Issue: 15(4), P. 760 - 760

Published: March 21, 2025

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.

Multiple Nitrogen Sources Application Inhibits Increasing Ammonia Volatilization Under Reducing Irrigation

Agronomy, Journal Year: 2024, Volume and Issue: 14(12), P. 2927 - 2927

Published: Dec. 8, 2024

Farmland ammonia (NH3) volatilization is an important source of NH3, and the application chemical fertilizer nitrogen (N) main factor affecting NH3 volatilization. The optimal substitution with organic manure straw reportedly reduces volatilization, while reducing irrigation increases However, combined effect on role microorganisms in this process remains unclear. In a soil column experiment, microbial composition were measured under both multiple N sources different levels by vented-chamber method metagenomic sequencing. results revealed that reduced cumulative 16.5–75.4% compared to single application, decreasing trend conditions was greater. Microorganisms had more than conventional irrigation. abundance nirA, arcC, E3.5.1.49, E3.5.5.1 (ammonia-producing) genes varied significantly at two levels. Overall, could inhibit increasing fertilizer. Our findings contribute valuable insights into
