Land salinization has become a global issue. To mitigate this issue, the modifiers and water-soluble fertilizers have emerged as promising strategy to enhance soil nutrient content promote crop production in saline soils. In study, based on hydrothermal method for preparing corn stalks derived biochar prepared using soda saline-alkali soil. Through field microplot experiments, separate interactive effects of different concentrations them were studied, well their influence growth alfalfa Leymus chinensis The combined application can effectively increase enzyme activity, significantly reducing pH alkalinity. It was found that optimal rate 20 g/kg improver resulted 4.99% decrease 11.23% Additionally, organic matter, available P2O5, NH4+-N, NO3--N contents increased by 25.74%, 28.48%, 19.87%, 32.90%, respectively. Soil activities generally peaked at fertilizers, with sucrase showing most significant increases, 31.14% 25.52% L. chinensis. Two-way ANOVA results demonstrated interaction between fertilizer pH, Ca2+ Mg2+ content, quick-acting potassium urease biomass leaf width. Moreover, planting indicated use modifies had effect promoting cultivation Our findings provided robust theoretical groundwork improving management soils optimizing such challenging environments.

This study presents a novel approach that integrates hydrothermal carbonization (HTC) technology with circular economy principles to optimize the management of nitrogen and phosphorus in agricultural wastewater. Given increasing global resource scarcity continuous ecological degradation, valorization biomass wastewater has become critical pathway for promotion sustainable development. Biomass wastewater, which contains crop residues, forestry leftovers, food processing byproducts, long been regarded as useless waste. However, this abundant organic matter possesses significant renewable energy potential. The can significantly reduce environmental pollution. Through optimization HTC process parameters, we achieved an improvement quality yield carbonized products, facilitating efficient recycling utilization resources. research demonstrates transform into valuable biofertilizers, energy, feed, while simultaneously reducing reliance on fossil fuels, decreasing greenhouse gas emissions, mitigating impact activities. paper provides comprehensive exploration application ecosystems, highlighting its beneficial role management, efficiency, pollution reduction. findings suggest holds potential optimizing treatment, promoting recycling, advancing Furthermore, offers theoretical support practical guidance implementation is paramount importance fostering economic development achieving agriculture.
