Full Description
This work seeks to furnish the soil testing laboratory with enduring technical literature on various aspects of soil testing, such as testing methods and fertilizer recommendation formulations, etc. The book has been carefully planned and offers detailed information on the major soil types found in India, their composition, plant nutrients, and their functions, as well as typical nutrient deficiency symptoms in plants. Additionally, it covers the procedures for collecting samples and the methods of analysis.
This book presents analytical concepts on nutrients, including principles, materials, equipment, methods, calculations, and interpretations, using clear and easily understandable language that enhances the clarity of the analytical methods employed.
This book will serve as an invaluable resource for soil testing in research laboratories, helping to advance research and prepare Soil Health Cards for farmers.
