Enviromental conditions and inadequate or excessive mineral nutrition can have serious implications on the quality of food crops. This book is a compilation of information on management tools which also reviews the factors affecting plant mineral nutrition and growth. It highlights the importance of fertilizers and mineral nutrition for improved agricultural production, yield and amelioration of soil fertility. The book also addresses issues such as growth, production, yield and quality, which can be limited by sub-optimal conditions such as soil, salinity, poor drainage, water supply, fertilization programmes, physical conditions affecting root growth and function or handling operations. The production of good quality food cannot be achieved without the strict control of the use of fertilizers and other pesticide sprays.
