Rice is the important cereal crop grown mostly on Indian soils irrespective of soil types and conditions. Zinc deficiency is common in flooded soils because of the reducing conditions that develop following submergence, with Zn becoming immobilized with ferrous iron compounds and other solid phases formed in reducing processes. The text presented in the book is sub divided into 7 chapters. This book envisages on how to improve the zinc use efficiency in paddy soil by different chemical and physical soil management. Suitable extractant of Zinc in a rice soil has also been described in detail. Source, rate and time of application of zinc for rice are very crucial for its optimum utilization and have been dealt separately with experimental evidence. This book is a comprehensive one and will meet the growing needs of soil science students for zinc management in paddy soil. Hopefully, the technical information contained herein will prove useful to students, teachers, scientists working in the field of Soil Science, Agronomy and Extension personnel.
