Opis

The book begins with an exploration of the history of soil fertility and plant nutrition, presenting the evolution of scientific understanding in this field. Fundamental concepts such as essential and beneficial elements, criteria of essentiality, and the roles of essential plant nutrients are discussed, along with methods for identifying nutrient deficiencies through plant symptoms. A detailed examination of macroand micronutrientsincluding nitrogen, phosphorus, potassium, secondary nutrients, and micronutrientsprovides a robust foundation for understanding their functions, dynamics, and management.A significant focus is placed on soil fertility evaluation, highlighting methods for assessing soil nutrient status through laboratory analysis and field diagnostics. The book also delves into fertilizer use efficiency and the methods and timing of fertilizer application, ensuring readers gain practical knowledge for optimizing nutrient uptake by crops.

To address the growing interest in sustainable agriculture, this book explores organic manures, chemical fertilizers and their classification, and nanofertilizers, with an emphasis on their properties, applications, and integration within modern nutrient management systems. The Fertilizer Control Order and the concept of Integrated Nutrient Management (INM) are also covered to ensure readers are acquainted with regulatory and sustainable practices. Additionally, the book discusses soil amendments, providing insights into improving soil structure and correcting soil pH for better crop performance.
