ABSTRACT A study was conducted to investigate changes that may occur in the soil due to conversion of forest land to plantation, fallow and arable lands. Four locations in two-agro-ecological zones at Ikole Local Government Area, Ekiti State, were used for this study. They are; Itapaji (L 1), Asin (L2); in rainforest agro-ecological zone and Odo-Ogo (L3), Odo-Ayedun (L4) in derived savannah. Soil parameters evaluated include particle size distribution, bulk density, saturated moisture conte...
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 ecological zones of south eastern Nigeria. The agro ecological zones were derived savannah and rainforest while the land use systems studied were cultivate...
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 and soil amendments, the amounts deposited onto soils from the atmosphere, and the amounts removed by harvested crops and by leaching. Its aim was t...
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 properties was also evaluated. The experiment was laid out in a Completely Randomized Design with four replications. Tithonia diversifolia was appl...
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 of soil survey. The objective was to generate detailed information on the properties of the soil for their sustainable agricultural use and managem...
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 locations under Sahel Savannah are Goronyo ,Gamawa and Minjibir while the site under Sudan Savannah are Hadeija and Ulela. A 5x4x3 factorial experime...
ABSTRACT Field experiment was conducted to evaluate the combined effects of drip irrigation frequency and different mulching materials on the growth and yield of okra (Abelmoschus esculentus L, Moench). The field experiment was 3 x 3 factorial using Randomized Complete Block Design. The factors were three irrigation intervals (daily, twice and thrice weekly) and three mulches (plastic, grasses and no mulch) and replicated four times. It was observed from the result that okra responded signifi...
ABSTRACT Management practices to adopt in improving the land productivity has always been a challenge. The arable land used for farm practical year students and the fadama used for raising vegetable.s and maize during the dry season are spoken about as not very productive. This is due to the gross lack of information on both the physical and chemical properties of the soils under the different land use types in the Federal University Oye-Ekiti. These land use types continued for over three ...
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 (WSOC). Soil samples were taken at 0-5, 5-10, I0-20 and 20-30 cm and 0-30 cm depths at each site using soil auger. The soil samples were analyzed fo...
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 due to conversion of forest to arable land. Six locations that were selected for this purpose include; Ona-Ara (Ll), Asin (L2), Ijesa Isu (L3), Odo-...
Abstract 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. At each location, three topographic units were identified as upper slope, middle slope and lower slope at 50 m apart. A mini pit of 150 cm by 100 cm ...
Abstract. Pepper (Capsicum spp.) production by farmers in southwestern Nigeria is limited by low yield due to poor genetic potentials of most cultivars available, use of poor quality seeds, disease infestation, and poor managment practices among others. To overcome the constraints, some varieties of pepper developed at Embrapa Brazil and NIHORT Nigeria, were introducedfollowed bytraining of 100 small scale farmers . Participatory field demonstrations of the improved varieties of pepper were c...
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...
Background and Objective: Aquic Arenic Paleudults soils are developed at valley bottom of a basement complex parent material of the sub-humid tropical rainforest. The aim of the study was to determine the mineralogy of clay components of Aquic Arenic Paleudults soils of Akpamkpa, Southeastern Nigeria. Materials and Methods: The study mineralogy of clay components of Aquic Arenic Paleudults soils of Akamkpa, southeastern Nigeria was carried out on 50 hectare land. Two soils were collected fro...
In precision Agriculture, geostatistical methods as a predictive tool have been extensively utilized. The approach estimates soil properties spatial variability and dependency. This study was carried out in Ovia north east Local Government Area of Edo State of Nigeria in order to map soil properties (Sand, Clay, pH, OC, P, N and CEC) and predict their spatial variability. Twenty-nine (29) soil samples were collected randomly from Typic Kandiudults soil type under three different land use, tea...
