Land capability needs to be assessed for a range of crops in specific agro-ecosystems of Cambodia to support moves to diversify crop production from the present heavy reliance on rice. Maize, soybean, mung bean, sesame and peanut appear to be the food crops of most interest initially. Usually soil constraints would be assessed for land capability classification from published land resource studies. Such information is generally unavailable for uplands in Cambodia at an appropriate scale. Hence further land resource assessment in the upland areas needs to be undertaken as a basis for a land capability assessment. Whilst a soil map and reports on soil constraints for lowland rice have been published, soil constraints for other crops have not yet been assessed for these soils. A framework for land capability classification was developed based on previous systems of land evaluation with modifications for Cambodia and to align the rating of land qualities to the Fertility Capability Classification. Land qualities were selected for tillage, crop germination and emergence, crop growth, and land and resource degradation risk. In subsequent papers, we report on the application of this classification to soils and landscapes of Kampong Cham, Takeo and Battambang provinces.
