Farmers apply fertilizers to crops in order to produce maximum economic return. To attain this, it is important that fertilizer requirements can be estimated accurately. The prevention of excessive use of fertilizers on economic grounds also has the beneficial consequence of minimizing environmental pollution of groundwaters through the leaching of unused fertilizers. This book is intended for both the agricultural scientist who is engaged in research on the use of fertilizers in crop production and consultants who might assist with the interpretation of statistical data. Relevant mathematical and statistical procedures are described critically, indicating their basis and limitations, and how they may be used or misused. Some basic knowledge of statistics is assumed on the part of the reader. Many of the procedures have been developed by the author from experience in soil fertility projects in Australia, Canada, the USA and a number of less-developed countries.

In Soil Fertility Management in Agroecosystems, Editors Amitava Chatterjee and David Clay provide a thoughtful survey of important concepts in soil fertility management. For the requirements of our future workforce, it is imperative that we evolve our understanding of soil fertility. Agronomists and soil scientists are increasingly challenged by extreme climatic conditions. Farmers are experimenting with integrating cover crops into rotations and reducing the use of chemical fertilizers. In other words, there is no such a thing as a simple fertilizer recommendation in today's agriculture. Topics covered include crop-specific nutrient management, program assessment, crop models for decision making, optimization of fertilizer use, cover crops, reducing nitrous oxide emissions, natural abundance techniques, tile-drained conditions, and soil biological fertility.

Fertigation requires a thorough understanding of the science behind the technology to make it deliver the immense possibility it offers in crop production. Though the idea of fertigation existed from the times of solution culture, it did not receive the necessary attention from among plant nutritionists and agronomists when it reappeared in the context of micro irrigation. Fertilizer application in field agriculture has also not developed as a precision technology. Recommendations of the quantum of fertilizers required for a crop, at least in India are not based on current varieties of the crops, nor have they anything to do with the growth rate and developmental changes occurring while a crop is managed by the grower. Most of the fertilizer recommendations are itself very old and efforts to make them relevant to the current growing conditions, soil status, crop variety and crops reaction to the environment etc. are very limited. It is even worse when growers follow traders’ recommendations whose idea is to sell more the fertilizer they supply. Not only lower yields and very low fertilizer use efficiencies, but the deterioration of soil and water bodies are the results.

The world population is projected to reach nine billion by 2050, and in the coming years, global food demand is expected to increase by 50% or more. Higher crop productivity gains in the future will have to be achieved in developing countries through better natural resources management and crop improvement. After nitrogen, phosphorus (P) has more widespread influence on both natural and agricultural ecosystems than any other essential plant element. It has been estimated that 5.7 billion hectares of land worldwide contain insufficient amounts of available P for sustainable crop production, and P deficiency in crop plants is a widespread problem in various parts of the world. However, it has been estimated that worldwide minable P could last less than 40 years. For sustaining future food supplies, it is vital to enhance plant P use efficiency. To bring the latest knowledge and research advances in efficient management of P for economically viable and environmentally beneficial crop production in sustainable agriculture, Phosphorus Management in Crop Production contains chapters covering functions and diagnostic techniques for P requirements in crop plants, P use efficiency and interactions with other nutrients in crop plants, management of P for optimal crop production and environmental quality, and basic principles and methodology regarding P nutrition in crop plants. The majority of research data included are derived from many years of field, greenhouse, and lab work, hence the information is practical in nature and will have a significant impact on efficient management of P-fertilizers to enhance P use efficiency, improve crop production, promote sustainable agriculture, and reduce P losses through eluviations, leaching, and erosion to minimize environmental degradation. A comprehensive book that combines practical and applied information, Phosphorus Management in Crop Production is an excellent reference for students, professors, agricultural research scientists, food scientists, agricultural extension specialists, private consultants, fertilizer companies, and government agencies that deal with agricultural and environmental issues.
