Emerging Trends in Agriculture Sciences (Volume – 4), edited by Dr. Yad Vir Singh, provides a deep dive into environmental and technological innovations addressing modern agricultural challenges. This volume features research on customized fertilizers, pesticide-induced water pollution, vermicomposting methodologies, green manuring for soil reclamation, and toxic element behavior in soil ecosystems. It also explores remote sensing for pollution monitoring and discusses biochemical tools like COD and BOD analysis. The book integrates practical field solutions with academic rigor, aiming to promote eco-conscious farming, nutrient efficiency, and sustainable soil practices. Ideal for agronomists, researchers, environmentalists, and students, this edition fosters holistic insights into pollution mitigation, organic amendments, and precision nutrient management. By combining environmental science, chemistry, and soil biology, it serves as a timely resource for agricultural resilience in the face of ecological degradation.
