Learn the fundamentals as well as in-depth details of agricultural cropping systems from around the globe! Cropping Systems: Trends and Advances is a comprehensive review of past and present research efforts in North America and other parts of the world. It brings together biological, economic, sociological, and technical aspects of cropping systems in a single source to provide a reference unlike any other on the subject that is available today. This valuable book also points to future directions that cropping systems research needs to take in order to increase sustainable agriculture and feed the growing world population. Charts, tables, and illustrations make the information easy to access and understand. An ideal textbook for graduate and undergraduate courses in agronomy as well as a comprehensive reference for professionals involved in cropping systems research, Cropping Systems: Trends and Advances is a book you’ll refer to again and again. Topics covered in this well-referenced and thoughtfully indexed book include: emerging trends in cropping systems research designing resource-efficient cropping systems soil quality and fertility tillage root dynamics water quality concerns nitrogen use efficiency precision agriculture agricultural biotechnology weed biology and management integrated pest management the important role that cover crops can play key indicators for assessing nitrogen use efficiency in cereal-based agroecosystems the implications of elevated carbon dioxide-induced changes in agroecosystem productivity and a great deal more!

"The national ARS Wheat Yeild project was formally initiated in October 1976 with objective of developing a concise description of plant response to its environment which would include capability for yeild prediction. This document describes some activities and products of the of the ARS Wheat Yeild Group. The products presented here include brief descriptions of (a) project development, (b) data sets developed by measuring soil, plant and climate parameters through complete growth cycles of winter wheat and spring wheat at several locations and years in the Great Plains and Pacific Northwest, (c) dynamic simulation models of wheat growth and yield, and (d) methods for using remotely sensed data to assess plant conditions, provide early warnings of poor (abnormal) growing conditions, and provide surrogate inputs to the plant growth models"--P.
