Land Capability Classification for Non-Rice Crops in Soils of Banan District, Battambang Province
The acceleration of crop diversification in Cambodia in lowlands and in uplands could be facilitated by a process for the assessment of land capability for non-rice crops. Maize, soybean, mung bean, sesame and peanut appear to be the crops of most interest initially for land capability assessment, together with cassava and sugar cane. Land capability was determined for maize, soybean, mung bean, sesame and peanut in Banan district, Battambang province. Limiting factors for crops were identified, and land qualities rated for the soil types identified previously in a soil survey of the district. The main Soil groups on Banan district are Toul Samroung, Kein Svay and Kompong Siem. The calcareous phase of Kompong Siem soils that occurs on the lower slopes of limestone hills has low capability for non-rice cropping with alkalinity and waterlogging being the most likely limiting factors. By contrast, the Kein Svay soil has high capability for non-rice crops especially on the high levee banks. Toul Samroung soil, where it occurs in slightly elevated land within the rice plains, has fair capability for non-rice crops, but it is not recommended for non-rice crops in the main wet season due to inundation risk.
