The second volume of Advances in Agrotechnology builds upon the foundations laid in the first, highlighting global progress in sustainable natural resource management. It addresses critical areas such as problematic soil and weed management, rainfed dryland farming, and water conservation through farm ponds and micro-irrigation, with an emphasis on water quality. Integrated nutrient management combining organic and inorganic inputs is discussed to maintain soil fertility and productivity. The book also explores the application of remote sensing and GIS in developing predictive models to reduce cultivation costs while considering climate impacts. A key highlight is the cost-effective biofortification strategies aimed at combating micronutrient malnutrition. Additionally, it features an insightful chapter on precision farming technologies suited for both developed and developing regions. The discussion on biological disease control adds further value. In an age of abundant information, the editors have curated and synthesized global research from reputed journals and publications to present clear, concise, and accessible content. Their effort ensures that readers, especially those navigating complex agricultural challenges, can benefit from well-organized knowledge tailored for practical application.
