The land-use types and the number of soil samples.

Land-use types	Description	No. of composite samples	No. of undisturbed samples
Natural forestland	An area with a dense growth of natural vegetation (trees and undergrowth) with minimal human interference	16	10
Grassland	An area dominated by elephant grass (Pennisetum purpureum Schumach), forbs, and other grasses	11	8
