Fertility status of soils within the south-south region of Nigeria varies both inter and intra states. Therefore, the study investigated the macronutrient status of some selected soils in Bayelsa State. Two farm sites in Opume (OPF) and Amassoma (AMF) with records of long term cultivation were randomly selected and soil samples randomly collected f...

Two particle sized biochar from locally pyrolyzed Rhizophora racemose in earthen kiln were assessed on the fate of aluminum (Al), lead (Pb), and zinc (Zn), and the effect on soil organic matter (SOM), organic carbon (SOC) and total nitrogen (TN). Soil samples contaminated with known concentration of crude oil were amended with < 2 mm (B1) and 2-4 m...

Soils contaminated at different levels of crude oil were amended with two particle-sized fractions of red mangrove biochar [<2 mm (B1) and 4 mm (B2)] from locally pyrolyzed red mangrove in earthen kiln and incorporated at five different rates (1, 2, 3, 4 and 6 mg ha-1) in the Teaching and Research Farm, Faculty of Agriculture, Niger Delta Universit...

Soil samples were analyzed to identify population of autochthonous aerobic heterotrophic bacteria (AHB) and hydrocarbon degrading bacteria (HDB) in soils of Bayelsa State. Soil samples collected from two locations (Okodia and Imiringi) at two different crude oil sites (polluted and unpolluted) at two soil depths (0-15cm and 15-30cm). Pour plate met...

The objective of the research was to determine the effect of different crude tillage implements on some soil physicochemical properties in Niger Delta University Teaching and Research Farms. The land was divided into plots measuring 5 x 5m with three replicates per treatment. Five tillage treatments were considered (no-till, Hoeing, Digging, Hoeing...

The objective of the study was to determine the short time effect of tillage system on the water retention capacity of soils in the Niger Delta University Teaching and Research Farm, Bayelsa State. Five treatments (No-till, Digging, Hoeing, Hoeing+Digging once, and Hoeing+Digging twice) were considered. Plant Available Water Content (PAWC) and the...

Due to the detrimental effect of water erosion, erosion data must be gathered for sustenance of soil structure and utilization. The aim of the study was to determine the erodibility status of the some soils in Akoko-Edo Local Government Area of Edo state, Nigeria. Soil samples were taken from representative pedons dug from the three communities nam...

Nine Nun River floodplain soils in Bayelsa State were evaluated using Land Capability Classification (LCC), Land Capability Index (LCI) and Fertility Capability Classification (FCC) systems. The LCC grouped most soil mapping units (SMUs) into class II except NDU3. Odi (ODI1), Koroama (KRM1) and Niger Delta University (NDU1) were grouped in IInf0; O...

A greenhouse study was conducted to assess the influence of locally pyrolysed feedstock in the mineralization of Potassium (K), Phosphorus (P) and Magnesium (Mg) and toxicity of Cadmium (Cd) and Nickel (Ni) heavy metals in soil. Separate amendments of Wood char (WC), Cattle dung (CD) and a combination of both Wood and Cattle dung (WCD) chars weighe...

Nine pedons of alluvial origin in the Lower Niger River floodplains of Nigeria were examined for morphogenesis, physicochemical properties, mineralogical composition, and heterogeneity of the parent materials. The soils were stratified with redoximorphic features observed in the different layers reaching A-horizon with subsurface grayization. Soils...

For increased agricultural production, the place of adequate knowledge of soil properties and reliable soil data in the management of floodplain soils cannot be down-played. This study therefore, was conducted with the objective of characterizing and classifying some alluvial soils of the lower Niger floodplain in Bayelsa State, Nigeria to provide...

As agricultural land in the Niger Delta area is dwindling due to inherent lack of dry and relatively well drained land and increase in population and competition from land for urbanization and industrialization, the need to monitor and manage the limited available land for agriculture becomes very paramount. This study seeks to evaluate the variabi...

Owing to the influence of topography on soil properties, studies on the variability of soil properties become imperative. This study assessed spatial variability of some selected soil properties in three physiographic units: upper slope, lower slope and recent alluvial soils on channels of present active river in two locations in Bayelsa State. In...
