Appendix -- Index. Soil Fertility Evaluation and Control presents the theoretical background for practical applications of scientific work on soil fertility. The book emphasizes the use of response curves as the basic biological standard for both evaluation and control, and it discusses soil testing and plant analysis as secondary standards. The principal applications covered include fertilizer requirements, fertilizer evaluation, residual effects, fertilizer placement, liming, and economics of fertilization. Environmental aspects of plant nutrients and soil nutrient supplies as they pertain to crop production are also addressed. Most of the information in Soil Fertility Evaluation and Control is drawn from world literature, which makes it a valuable reference for soil scientists, agronomists, agriculturalists, foresters, and others interested in the evaluation and control of soil fertility.
