Description :
This paper will emphasize the importance of soil texture in terms of improving irrigation by summarizing some results of longtime studies about soil water dynamic under the influence of irrigation. Furthermore, the paper presents possibilities of optimizing irrigation on the basis of 2 simulation approaches. In the first simulation approach a multi-agent-based tool calculates soil specific and corresponding water tensions by using pedotransfer functions. The second simulation approach calculates a field-irrigation with simultaneous consideration of the horizontal variability of soil properties. Both approaches show that precision and soil specific irrigation is accompanied by a significant reduction of irrigation water and an improvement of irrigation efficiency.
