Leaching Requirement
A Leaching Requirement is a basic concept in irrigation and soil management that helps farmers and irrigation specialists determine how much extra water needs to be applied to crops to wash away harmful salts from the soil. Think of it like a soil cleaning process - just as you might need to rinse dishes extra thoroughly to remove soap residue, crops need extra water beyond their basic needs to prevent salt buildup that could harm their growth. This term often appears in resumes of irrigation specialists, agricultural consultants, and farm managers who work with water management systems.
