Analysis of plant materials for macro and micronutrients. 13. Tissue testing for major plant nutrients (N P and K). 13. Analysis of irrigation waters. 15. Analysis of fertilisers for major and micronutrients. The main aim of writing this book is to facilitate the advancing students in the field of soils plants irrigation water and fertilizers etc. It has been compiled for the practicing chemists in research laboratories and students. In this book author has compiled together some tested widely used methods for the determination of plant nutrients and quality parameters in soils plants water and fertilizers. In case of soils methods described are for nutrients considered as immediately available for providing an assessment of the available nutrient status. These plant analysis are valuable for students researchers and plant analysis laboratories for advisory purposes. This book has been prepared to meet the needs of teaching research fertilizer production advisory services soil plant water testing laboratories. This book will be useful for educational institutions interested in soil science plant analysis water management and fertilizers. 173 pp.
