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… Continue Reading
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… Continue Reading
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… Continue Reading
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… Continue Reading
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… Continue Reading
Anthropogenic activities can destroy or drastically reduce the organic carbon contents of soils. This study was conducted to evaluate the effects of two land use management practices (arable land and oil palm land), soil depth and topography on soil organic carbon contents. The study was carried out in Ikole-Ekiti, Ekiti State, Nigeria.… Continue Reading
ABSTRACT Forest soils in Ekiti state western Nigeria are destroyed due to agricultural activities. Information about the effect of land use on soil is important for soil sustainability and productivity. A study was conducted to investigate changes that may occur in the soil organic carbon content (SOC) and some selected soil physical properties… Continue Reading
ABSTRACT This research was conducted in Ikole-Ekiti to evaluate the effects of four land use types (forest plantation, arable land, fallow land and ranchland) and soil depth on soil organic carbon fractions namely; particulate organic carbon (POC), soil microbial biomass carbon (SMBC), total organic carbon (TOC) and water soluble organic carbon… Continue Reading
ABSTRACT Exploring the impact of changes in land use in soils of the desert margin soils in Nigeria .This research is a key component to global climate change. Soil samples were taken in two vegetation zone Sahel and Sudan Savannah under four different land uses( Forest Area, Arable land, Fallow land and Grazing land) at a depth of 0-15cm. The… Continue Reading
ABSTRACT Sustainable use of soils requires in-depth knowledge of the formation, genesis and properties of soil. It is in view of this that some soils derived from granitic parent rock in Ikole, South- western Nigeria covering 33.7 hectares of land where mapped at a scale of 1:50,000 using a combination of convectional and remote sensing methods… Continue Reading
ABSTRACT Greenhouse study was conducted at Federal University Oye- Ekiti, Department of Soil Science and Land Resources Management between June and August 2016 to compare the growth and yield of maize (Zea mays L.) using different rates of organic (Tithonia diversifolia) and Inorganic fertilizer. The effect of the amendments on the soil chemical… Continue Reading
ABSTRACT Cadmium (Cd) is a common environmental contaminant found in soils. Unlike other metals. Cd has no biological role, and is potentially toxic to microorganisms. The concentrations of cadmium in agricultural soils depend upon the amounts present in the parent rocks from which the soils form, the amounts added in the form of fertilizers… Continue Reading
Abstract The Information on the effect of different land use systems on the aggregate stability and carbon sequestration is crucial for the recommendation of efficient land management practices. This study was conducted to evaluate the variation in aggregate stability and carbon sequestration under different land use systems in two agro… Continue Reading
The land at Anuka, Nsukka Local Government Area of Enugu State in Southeastern Nigeria, under the sub-humid tropical climate was evaluated for maize (Zea mays), cassava (Manihot esculenta), yam (Dioscorea spp.) and oil palm (Elaeis guineensis) cultivation. Data were obtained by field study and laboratory analyses. Six pedons were dug and… Continue Reading
One mechanism by which plants can mobilize organic and inorganic forms of phosphorus (P) in soils is by exudation of low molecular weight organic acids. Laboratory and field trial were carried out during 2011 and 2012 cropping seasons to study the effects of additions of organic acids ( citric, oxalic and tartaric acids) on the… Continue Reading
