Sustainable Practices in Water Management for California Cotton: Best Management Approaches

This comprehensive overview explores sustainable water management practices in California's cotton industry. It discusses historical influences, such as tribal water use, early developers, and significant legal cases like the Miller-Haggin Agreement that shaped water rights. The text highlights advanced techniques, including regulated deficit irrigation, GPS technology, and drip irrigation systems, aimed at reducing water demand while maintaining high yields. The focus on sustainability not only supports environmental sensitivity but also enhances agricultural diversity and economic viability in California's San Joaquin Valley.
