Mapping of irrigation need based on computerized soil and climatic data

A nation-wide mapping of irrigation need based on computerized soil and climatic data has been carried out. Based on the Danish soil classification and pedological investigations approximately 36 000 profiles have been constructed, and the root zone capacities for grass and barely have been calculat...

Zusammenfassung:	A nation-wide mapping of irrigation need based on computerized soil and climatic data has been carried out. Based on the Danish soil classification and pedological investigations approximately 36 000 profiles have been constructed, and the root zone capacities for grass and barely have been calculated. Based on an empirical model with daily values of potential evapotranspiration and precipitation as driving variables the relationship between root zone capacity and irrigation need for different climatic zones has been outlined and an irrigation map constructed.
