Book Description
The role of the agricultural scientist is to manipulate crop and livestock response phenomena so that they serve society's needs better, enabling countries to obtain full benefit from their agricultural resources. By producing food more efficiently, resources can be made available for non-agricultural development and other needs beyond the essentials of food and fibre. This text provides an introductory outline of the analytical principles involved in appraising the efficiency of crop-fertilizer and livestock-feed response. It provides students of both agricultural science and economics with a simple but formal exposition of the why, how and wherefore of the principles of crop and livestock analysis, thereby helping to further co-operative effort among biological and economic researchers. The third edition has been updated and revised, with additions relating to the principles of modelling, the concept of economic duality as pertinent to response processes, the appraisal of aggregate response, and the economics of response research.

Book Description
In The Story of N, Hugh S. Gorman analyzes the notion of sustainability from a fresh perspective—the integration of human activities with the biogeochemical cycling of nitrogen—and provides a supportive alternative to studying sustainability through the lens of climate change and the cycling of carbon. It is the first book to examine the social processes by which industrial societies learned to bypass a fundamental ecological limit and, later, began addressing the resulting concerns by establishing limits of their own The book is organized into three parts. Part I, “The Knowledge of Nature,” explores the emergence of the nitrogen cycle before humans arrived on the scene and the changes that occurred as stationary agricultural societies took root. Part II, “Learning to Bypass an Ecological Limit,” examines the role of science and market capitalism in accelerating the pace of innovation, eventually allowing humans to bypass the activity of nitrogen-fixing bacteria. Part III, “Learning to Establish Human-Defined Limits,” covers the twentieth-century response to the nitrogen-related concerns that emerged as more nitrogenous compounds flowed into the environment. A concluding chapter, “The Challenge of Sustainability,” places the entire story in the context of constructing an ecological economy in which innovations that contribute to sustainable practices are rewarded.

Book Description
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.
