Résumé du livre
The study was undertaken to develop and test a model capable of simulating the changes in national and regional variables relating to agricultural production as the level of sheet and rill erosion from cultivated lands is controlled. the model incorporates the major agricultural commodities and determines their pattern of production in 223 areas of the continental United States. within each area, nine land classes were defined based on the erosion characteristics of the soils. the production of the alternative crops is allocated to these areas and land classes based on their economic advantage and compatibility with restraints.
