This book “Soil Zinc fractions and Nutritional composition of Seeded Rice” is the outcome of research experience in soil science. Rice [Oryza sativa (L.) family Graminae] is one of the most important and valuable cereal crop in world. The largest cultivated area of India subcontinent is planted with paddy. During the last few years, zinc has assumed greater importance in crop production and its deficiency in the field crops, has been recognized on an extensive scale. Farm yard manure, poultry manure and piggery manures also exert positive effect on the major as well as micro nutrients availability. Till date very meagre information is available in the literature on different forms of zinc and their availability in black soils. Thus, the knowledge and information about the effect of zinc and different organic matter on soil zinc fractions and nutritional composition of seeded rice under vertisols is essential.
