This book entitled “Manual on Manures, Fertilizers and Agro-Chemicals” brought out by Dr. A. S.Mailappa, is a comprehensive treatise on the subject and is an outcome of his visionary perception and quest of a great need for an easy ready reckoner practical manual. This book addresses the various exercises / experiments as laid out in the syllabus of various undergraduate courses offered during the undergraduate programmes of Agriculture, Horticulture and Forestry.

This book has 20 well-defined chapters covering various aspects on collection, preparation, analysis of manures, fertilizers and agrochemicals, including things to learn at the end of every chapter. The contents are presented in such a way that the readers shall easily understand various aspects of analysis of test samples.

It is written in a very simpler and lucid manner, to ensure easy and clear understanding about execution of various practical experiments including step- by-step calculations and interpretation of analytical results related to analysis of manures, fertilizers and agrochemicals.

This book will serve as a guide for them to understand various analytical principles and user-friendly instrumental methods on the subject and thereby helping them to progress ahead in acquiring in-depth knowledge on carrying out of various research activities / programmmes in the field of agriculture and allied disciplines.

Readership : Students / Teachers / Researchers / Lab-technicians of Agricultural Universities / Institutes, engaged in analysis of Manures, Fertilizers and Agro-Chemicals.
