The North China Plain (NCP) is a remarkable agricultural area with severe water scarcity and uneven precipitation, especially in wheat season. Optimizing irrigation strategies to increase productivity (WP) achieve higher yield winter wheat-summer maize rotation urgently needed has been persistent challenge. A four-year field experiment was conducted explore the impact of on WP subsequent under different precipitation year types (dry normal years, categorized based cumulative from sowing jointing stage (P1)). Four (W0, no irrigation; W1, pre-sowing W2, + W3, anthesis irrigation) were adopted for wheat, identical operations applied maize. Results showed that affected by P1 rather than total precipitation. Irrigation improved enhancing evapotranspiration, spike number, grain 1000-seed weight. water-limited gap between W2 W1 significantly those W0, W3 implying suitable strategy production. Different season had effect but increased 13.2–29.3% 16.1–41.8% compared other treatments through decreasing soil storage before dry years. Therefore, we recommended annual yield, WP, net income years (37.6 mm < 79.9 mm); lower consumption economic benefits (P1 37.6 mm), respectively. Overall, optimizing conditions an effective cope resource shortages crop NCP.

Soil moisture (SM), as a crucial input variable of land surface processes, plays pivotal role in the global hydrological cycle. The aim this paper is to examine spatiotemporal variability SM Heihe River Basin using all-weather temperature (LST) and reanalysis data. Initially, we downscaled generated daily 1 km data (2020) for Basin. Subsequently, investigated spatial temporal patterns geostatistical time stability methods. driving forces monthly were studied optimal parameter-based geographical detector (OPGD) model. results indicate that mean values range from 0.115 0.146, with consistently lower content suitable throughout year. Geostatistical analysis revealed months higher level exhibit larger random errors variability. Driving based on factor demonstrated level, q each are relatively small, primary factors cover elevation. Conversely, larger, normalized difference vegetation index LST. Furthermore, interaction suggested variation not influenced by single but result among multiple factors, most interactions enhancing combined effect two factors.

The escalating production of biosolids from wastewater treatment plants presents significant environmental and health challenges due to the presence pathogens, trace organic pollutants, heavy metals. Transforming into biochar through pyrolysis offers a sustainable solution, enhancing soil fertility mitigating greenhouse gas emissions. This review critically evaluates processes (slow, fast, flash) for biosolid conversion examines impact biosolid-derived on nutrient retention, crop productivity, Findings various studies demonstrate that BDB can significantly reduce emissions N2O, CH4, CO2 while improving health. However, such as standardizing methods, addressing metal content, ensuring economic feasibility must be overcome. Future research should focus optimizing conditions, developing regulatory frameworks, conducting comprehensive analyses support large-scale implementation in agriculture.
