Soil, Plant, Water and Fertilizer Analysis

About this book

This manuscript is a compilation of some tested and widely used analytical method of characterizing soil, plant, water and fertilizers. The text presented in the book is sub-divided into nineteen chapters and four appendixes dealing with procedures of quantifying various physical and chemical properties of soil, water and fertilizers as well as chemical composition of plant material. Some analytical concepts related to soil microbiology and water biology have been dealt separately. The method given are described under four sub headings, Principle, materials, equipment, method and calculation. Brief explanations of the important steps have also been included. Modifications in the method and calculations are made wherever felt necessary for providing better understanding and clarity about the subject.
