Technical Specification for Alternate Irrigation of Slightly Saline Water and Freshwater and Soil Improvement in Heavy Saline-Alkali Land of Yellow River Irrigation Area

This technical specification provides a comprehensive framework for managing agricultural land in the Yellow River irrigation zone, specifically targeting areas affected by severe salinity and sodicity. It outlines procedural guidelines for alternating between brackish and fresh water sources to improve soil quality over time. The document details operational methods for integrating water application strategies with soil remediation techniques, aiming to restore arable land functionality while preserving water resources. It addresses site preparation, water quality parameters, irrigation scheduling, and monitoring requirements essential for effective implementation. The guidance ensures that local agricultural practices align with sustainable land management principles tailored to the specific environmental conditions of the region. By establishing clear technical criteria, this regulation supports the long-term productivity of saline-alkali soils through systematic hydrological adjustments and soil improvement measures. It serves as a practical reference for implementing reclamation projects in similar climatic and hydrogeological settings without making direct claims about urgency or specific outcomes beyond the defined technical scope.
