Nutrient management involves using crop nutrients as efficiently as feasible to enhance productivity while protecting the environment. The key principle behind nutrient management is balancing soil nutrient inputs with crop requirements. When applied in proper quantities and at the right times, delivered nutrients help obtain optimum crop yields. Fertilizers are manufactured combinations of chemical products that comprise the main and different necessary nutrients. The book has been collected to deliver a wide-ranging understanding knowledge and to improve the practical capability of the under-graduate students based on the curriculum. The subject contents have been introduced to make it easy and simple for the students. This book aims at understanding the many aspects of nutrient management and fertilizer technology activities which have direct as well as indirect effects on the growth and development of crops. Thus, in a broad sense, the book will be very beneficial for undergraduate Agricultural college students to enrich their understanding of nutrient management and fertilizer technology. This book is having more scope for preparing, JRF, SRF, NRT-based examination.
