Book Description
The third most important cereal crop after wheat and corn, rice is a staple food for more than half of the world’s population. This includes regions of high population density and rapid growth, indicating that rice will continue to be a major food crop in the next century. Mineral Nutrition of Rice brings together a wealth of information on the ecophysiology and nutrient requirements of rice. Compiling the latest scientific research, the book explains how to manage essential nutrients to maximize rice yield. The book examines 15 essential or beneficial nutrients used in irrigated, upland, and floating rice across a range of geographic regions. For each mineral, the text details the cycle in the soil–plant system as well as the mineral’s functions, deficiency symptoms, uptake in plants, harvest index, and use efficiency. It then outlines management practices, covering application methods and timing, adequate rates, the use of efficient genotypes, and more. The author, an internationally recognized expert in mineral nutrition for crop plants, also proposes recommendations for the judicious use of fertilizers to reduce the cost of crop production and the risk of environmental pollution. Color photographs help readers identify nutrient deficiency symptoms and take the necessary corrective measures. Packed with useful tables and illustrations, this comprehensive reference guides readers who want to know how to increase rice yield, reduce production costs, and avoid environmental pollution from fertilizers. It offers practical information for those working in agricultural research fields, in laboratories, and in classrooms around the world.

Book Description
Rice is one of the oldest cultivated crops on earth and half of the world's population subsists wholly or partially on rice. Applying nutrients to the crop is essential in managing soil fertility so the plants grow and develop normally. A number of crop problems can be related to inefficient management of nutrients and nutrient imbalances in the field. Rice crops need to have the optimum nutritional balance. Macro-elements are needed by plants in large amounts. These are carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. While microelements are only needed in lesser quantities, often in trace amounts. These are iron, manganese, copper, zinc, molybdenum, boron, and chlorine. In this text we review key issues determining nutrient management strategies in irrigated and rainfed lowland riceland and present examples of nutrient management strategies. If rice crops have more or less than the required amount of nutrients, the yield can be greatly affected. Mineral Nutrition of Rice focuses attention on rice crop nutrient necessities, assessment of soil nutrient delivering capacity, and features of soil microorganisms in a long-term fertilization experiment based on nutrient balance concepts. Also, the relationships between the microbial biomass and chemical properties of the soil, such as available N, P and K contents are highlighted. The investigation aimed at analyzing the effects of fertility on soil microbial biomass and soil nutrient supplying capacity, and at considering implications for the long-term management of paddy soil fertility.Soil nutrient deficiency and unbalanced fertilization to rice crop had negative effect on the diversity of the microbial community and total microbial biomass in the soil. The long-term fertilizer experiment also showed that balanced application of N, P and K promoted microbial biomass growth and improvement of community composition. Unbalanced fertilization reduced microbial N and increased C/N ratio of the microbial biomass.
