Achievements in modeling of energy requirements for tillage tool

Abstract: Modeling of tillage tool energy requirement has been carried out since 1960s. In recent years, the development of more powerful computers and more sophisticated computer models and software have dramatically increased our ability to modeling and predict the performance and power requirements of tillage tools in various kinds of tillage operations, such as soil movement by tillage tool, soil failure profile and crop residual managements and manure injections, etc. Variety of mathematical models have been developed using analytical, numerical and empirical approaches. This paper attempts to provide a clear overview of these models and summarize the studies have been carried out in the area of modeling energy requirement of tillage tools. Furthermore, the paper gives the descriptions and characteristics of these models validations and suitable cases of applications.
