    During the last 40 years, the quantity and spatial patterns of farmland in Western Jilin have changed dramatically, which has had a great impact on soybean production potential. This study used one of the most advanced crop production potential models, the Global Agro-Ecological Zones model, to calculate the soybean production potential in Western Jilin based on Cited by: 2. The erosion and sediment transport processes in shallow waters, which are discussed in this paper, begin when water droplets hit the soil surface. The transport mechanism caused by the consequent rainfall-runoff process determines the amount of generated sediment that can be transferred downslope. Many significant studies and models are performed to investigate Cited by:

    This book, based on work sponsored by the Natural Resources Systems Programme of the UK Department for International Development, reviews progress in crop-soil simulation modelling and assesses its application to agriculture in developing countries. The books is divided into sections based on a classification of models with different functions. A group of Canadian, US and Mexican natural resource specialists, organized by the Pacific Northwest National Laboratory (PNNL) under its North American Energy, Environment and Economy (NA3E) Program, has applied a simulation modeling approach to estimating the impact of ENSO-driven climatic variations on the productivity of major crops grown in the three countries.

This model will be used to de termine the relationship between erosion and productivity for the USA. Thus, a national ARS erosion-productivity modelingteam was organized and began developing the model during This team.

The EPIC model is a sophisticated descendent of the Yield Soil Loss Simulator, the model used to evaluate erosion-produc- tivity effects in the RCA appraisal. The model draws upon NRI erosion estimates to develop baseline conditions and can simulate ero- sion rates and long-term productivity effects that would be expected from alternative.

The main adjustment for adapting the model to this dry Mediterranean environment was the inclusion of water-harvesting systems, which capture and use surface runoff for crop production in upstream subbasins, and a.

Environmental Policy Integrated Climate (EPIC) model is a cropping systems model that was developed to estimate soil productivity as affected by erosion as part of the Soil and Water Resources Conservation Act analysis for EPIC simulates approximately eighty crops with one crop growth model using unique parameter values for each crop.

In this research, the crop model EPIC (Erosion Productivity Impact Calculator) was adapted for simulations at regional scales. Satellite remotely sensed data provide a real-time assessment of the magnitude and variation of crop condition parameters, and this study in-vestigates the use of these parameters as an input to a crop growth model.
