DOWNLOAD EBOOKVolume 71 contains six outstanding reviews that discuss cutting edge developments in the crop and soil sciences. Chapter 1 addresses advances in the development, use, and evaluation of controlled release fertilizers. Chapter 2 is a comprehensive review of developments in breeding crops for increased nutritional value. Historical and current advances in the field are covered as well as selection in methodology and employment of molecular biology tools. Chapter 3 is a comprehensive treatment of remaking bean plant architecture for efficient production. Chapter 4 is a review on carbon sequestration, specifically, the potential of world cropland solid to serve as a source of atmospheric carbon. Chapter 5 discusses the ability of grain legumes (pulses) to adapt to water-limited environments. Chapter 6 describes and applies an important water quality model - the root zone water quality model (RZWQM). The model is described and discussion is provided on the calibration and application in laboratory and field settings.

DOWNLOAD EBOOKIn the 8th book of Dr. Ahuja’s innovative “Advances in Agricultural Systems Modeling” series, authors give a look into the future of climatesmart agricultural systems, emphasizing the integration of soil, weather, vegetation and management information to predict relevant agro-ecosystem processes. Expansion of data availability, improvement of sensors, and computational power have opened opportunities in modeling and exploration of management impact. Authors give a background on model development and explain soil, plant, and climate processes and their interactions that encompass the wide range of applications of simulation models to address challenges in managing our resources and complex agricultural systems.

DOWNLOAD EBOOKWhy model? Agricultural system models enhance and extend field research...to synthesize and examine experiment data and advance our knowledge faster, to extend current research in time to predict best management systems, and to prepare for climate-change effects on agriculture. The relevance of such models depends on their implementation. Methods of Introducing System Models into Agricultural Research is the ultimate handbook for field scientists and other model users in the proper methods of model use. Readers will learn parameter estimation, calibration, validation, and extension of experimental results to other weather conditions, soils, and climates. The proper methods are the key to realizing the great potential benefits of modeling an agricultural system. Experts cover the major models, with the synthesis of knowledge that is the hallmark of the Advances in Agricultural Systems Modeling series.

DOWNLOAD EBOOKThis publication comes with computer software and presents a comprehensive simulation model designed to predict the hydrologic response, including potential for surface and groundwater contamination, of alternative crop-management systems. It simulates crop development and the movement of water, nutrients and pesticides over and through the root zone for a representative unit area of an agricultural field over multiple years. The model allows simulation of a wide spectrum of management practices and scenarios with special features such as the rapid transport of surface-applied chemicals through macropores to deeper depths and the preferential transport of chemicals within the soil matrix via mobile-immobile zones. The transfer of surface-applied chemicals (pesticides in particular) to runoff water is also an important component.

DOWNLOAD EBOOK"Researchers and practitioners will gain insight into the current and oncoming challenges in providing food for the hungry around the world. The neglect of environmental factors would inevitably lead to the collapse of both industry and agriculture. Agricultural and Environmental Sustainability: Considerations for the Future focuses on the economic, ecological, and sociological issues that intertwine with efforts for effective agricultural sustainability in the coming years. This crucial look to the future provides a clear view of what needs to be done in long-term land use to ensure sustainability of resources, economic viability, and environmental preservation."--PUBLISHER'S WEBSITE.
