Effects of Land Use Types on Soil Productivity Parameters: A Case Study of Ogbomoso Agricultural Zone, Southern Guinea Savanna Ecology of NigeriaPages: 29-40
Authors: Folasade Mary OWOADE
Soil properties and soil management are two important factors that determine crop yield, knowledge of soil characteristics is foremost in ascertaining the better way to which a soil may be used. Impact appertaining to varied land use types, namely: maize cropping and cassava cropping, tree plantations and secondary forests on soil carbon accretion and soil productiveness in Ogbomoso agro-ecological zones of Oyo State within Southern Guinea savanna vegetation zone of Nigeria was investigated. Top soils (0-20 cm) were sampled from 100 farms of diverse land use types. The location of the farms and forest reserve were also considered as treatment factors. The representative soil were processed and analysed for some selected chemical and physical attributes. Soil productivity diminished in the order of forest >plantation >cassava >maize. Land use types had significant (Lsd ? 0.05) impact on the soil carbon storage, Ca, Mg, K, ECEC, organic carbon, Fe, P, Mn, Zn and pH. The results revealed that for sustainable soil fertility and productivity, there must be careful choice of land that is appropriate for agricultural purposes. Though there is nutrient decline in all land use types, this would be necessary to reduce rapid soil nutrient depletion, and would enhance soil productivity.
