This book was released on 2020-01-22 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why 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.

This book was released on 2012-12-06 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of the book Soils and the Environment imagination in the applications of soil surveys, illustrates the need for further, more detailed toward the end of improving productivity and information about soil survey interpretations (uses efficiency in the use of soils and the environment. of soil surveys), especially for laypersons, teachers, Although laypersons, teachers, and students are the and students. Much information about soils and primary groups addressed by this Field Guide, the environment is secluded in offices of various other people involved with using soil surveys are agencies and institutions and thus is not readily (or will be) agriculturalists, agronomists, assessors, available to the people who need it. Techniques for botanists, conservationists, contractors, ecologists, finding and using the information are also not well economists, engineers, extension workers, fores known, so there is great need for this Field Guide ters, geologists, groundwater experts, planners, to Soils and the Environment to provide teachers politicians, public health officials, range managers, and learners with exercises that will give them recreationists, soil scientists, wildlife specialists, and many others. This Field Guide complements practice leading to confidence in the manipulation and enhances the book Soils and the Environment and utilization of soil survey data. In a sense, all published in 1981. of us are (or should be) learners and teachers in the use of soil survey information. This Field Guide DONALD R.

Available in PDF, EPUB and Kindle. Book excerpt: The literature which has been reviewed presented overwhelming evidence for the need to consider weather in agricultural experiments. The primary purpose of this study has been to find a single atmospheric-soil moisture stress variable which is correlated with final corn yield. It is hoped that the use of this moisture stress variable will facilitate and encourage the consideration of weather with other environmental and technological factors in agricultural research and extension. The consideration of the weather will help evaluate the spatial and temperal representativeness of experimental results. Two atmospheric-moisture stress variables were found to be highly correlated with unreplicated plot corn yields from secon year corn in the 4-year rotation experiment, corn-corn-oats-meadow, at the Iowa State University Agronomy Farm, Ames, Iowa. One of the variable was the number of days on which the corn was estimated to be under no moisture stress, in the period 6 weeks before 3 weeks after date of silking. The estimation of moisture stress or no moisture stress conditions was based on the experimental relation found by Denmead and Shaw (10). OTL = f(ETFC), where OTL is the percent available soil moisture below which the corn plant loses turgor. The amount of available soil moisture at the turgor loss point depends upon the atmospheric demands or the evapotranspirations at field capacity, ETFC. The ETFC was estimated from the daily evaporation form a weather Bureau class a evaporation pan. (...).
