Potential of soils for growing cassava and sugarcane on toposequence of sandstone low hill atKrissana subdistrict, Sikhiu district, Nakhon Ratchasima province was undertaken on four locations, summit slope,upper middle slope, lower middle slope, and footslope of low hill. All four soils were classified as Typic Paleustults.They were deep soils with well drained feature. Groundwater depth at the time of sampling was between 125-200 m where the soil on the middle slope had the shallowest ground water level of 125 m. Their topsoils had brown tostrong brown colours. The colour of subsoils of soil on the summit was red and became yellow with a presence of mottles in soils located on the middle slope to the lowest position of the study area. Physico-chemical... |
