ABSTRACT The relative contributions of clay and organic matter to the cation exchange capacity of soils have been of great interest to many researchers. Organic matter. as a critical component of the soil. plays. significant roles which far exceed its quantitative distribution in the soil. It is regarded as the major contributor of CEC in weathered soils because of its several functional groups such as R-COO-. R-C=O. R-COH and R-SI I that deprotonate and leave net negative charges on the...
ABSTRACT The study was carried out in Dekina Local Government Area of Kogi State to determine the soil quality indicators. Among the towns which the research was carried out are ABOCHO, EGUME, AND OJIKPADALA. The area is characterized by sandy layer, sand content ranged between 78.6% and 84.6%, silt ranged between 1.72% and 4.72% and clay ranged from 13.68% to 17.68%.The pH of the soil was found to be acidic and ranged between 4.8 and 6.9.The soil organic carbon ranged between 0.57% and 1.04%...
ABSTRACT A laboratory experiment was set up at Kogi State University Anyigba at the faculty of Agriculture, department of soil and environmental management Laboratory to evaluate the effect of different levels of poultry manure on total heterotrophic bacteria in a cropped soil. Soil samples were collected from many random points at the Kogi State University Teaching and Research Farm at a depth of 0-15cm using an auger. The collected samples were bulked into one composite sample which was tak...
This research work was carried out on the rice soils of Ebonyi State, considering the cation ratios distribution in upland, lowland and irrigated rice in the three agro-ecological zones of Ebonyi, namely; Ebonyi North, Ebonyi Central and Ebonyi South. The location at Ebonyi North was at Amachi Izzi in Abakaliki and designated by AUP, ALP and AIP for Abakaliki Upland, Lowland and Irrigated pits respectively. Ebonyi Central was located at Ikwo and designated by IUP, ILP and IIP for Ikwo Upl...
The study was carried out at Agubia Ikwo in Central Ebonyi State and aimed at using Digital Elevation Model (DEM) in suitability evaluation of some selected soils for rice production. Three rice growing soils were identified in the area which include upland, lowland and irrigated rice soils. Three profile pits were sunk in each of the three rice cropping soils summing up to a total of 9 profiles. Suitability evaluations indicated that soil climatic requirements as well as soil physical condit...
ABSTRACT The concern of humanity is the need to tackle the increasing challenges of severe land degradation and desertification of the ecosystem. The study examined the impacts of agroforestry practices on soil fertility in rural areas of Katsina State, Nigeria. Purposive sampling technique was employed in collecting data from one hundred (100) rural farmers with structured questionnaire administered in two Local Government Areas of Katsina State, namely Batsari and Safana. The data were anal...
ABSTRACT One of the most serious problems currently affecting agricultural production in developing countries especially Nigeria is land degradation. The adverse effect of land degradation on soil production, soil health and food security is an important current global issue. Hence, this study assessed the chemical degradation of soils under kolanut production with the view of optimizing its production through appropriate management practices that is environmentally friendly and sustainable. ...

The study was conducted for distribution of total and exchangeable K from different cropping system, yam farm, fallow land and eucalyptus plantation, the sample was collected from the teaching and research farm of the Federal University of Technology at the depth of 0-15cm on the soil surface. The soil samples were collected from nine points along three random sites, the soil where then bulked together. The physical and chemical analysis as carried out, the total and exchangeable potassi...
