Assessment of the Water Conservation Potential and Mode of Application of Coconut (cocos Nucifera) Husk Hydrogel on Soil Cultivated to Coconut Seedling

M.O. Ekebafe^*, L. O. Ekebafe, OSAYANDE P.E., F. Maidoh, P. Irhemu

Coconut husk cellulosic-polyacrylonitrile hydrogel was synthesized in aqueous solution. Saponification of grafted copolymer was done by reaction with sodium hydroxide followed by methanol precipitation. The reaction was confirmed using FTIR and characterized in terms of water retention value (286g/g) and de-swelling ratio (83.16%). Soil samples collected were prepared and analyzed for physico-chem...

Geostatistical investigation and GIS-based spatial distribution of some micronutrients in Wukari soils, Taraba State, Nigeria

Waizah, Y.^*, Adashu Tanko Gani

Mapping soil fertility is important for site-specific nutrient management, it gives an insight into soil nutrient content, which is crucial for land use planning, fertilizer recommendations, and sustainable management of soil resources. Micronutrient deficiency in the soil is a serious limitation for crop production. Evaluation and mapping the soil micronutrients of a particular area can be a poss...

Assessment of Land Use Pattern and Land Form on Selected Physico-Chemical Properties of Soils Developed on Basement Complex-Sedimentary Transitional Zone of South Western Nigeria

AJIBOYE G. A.^*, OLANIYAN J. O., BOSIAKO C., OYETUNDE O. O.

The effects of cropping practices and soil management on the properties of basement complex- sedimentary transitional zone soils in South Western Nigeria was assessed using soil samples from the pedogenic horizons of ten profile pits dug on two land-use systems (subsistence and experimental farms) and two toposequence. The land use significantly (P

Nitrogen and Phosphorus Dynamics in a Legume Based Integrated Nutrient Management System

Amusan O. A.^*, Adetunji M. T, Jamiu Oladipupo Azeez

This study was carried out on a tropical alfisol for two consecutive years to investigate the effect of a legume based integrated nutrient management system on the soil status of nitrogen and phosphorus. The treatments consisted of two rates of poultry manure (0 and 5 t ha-1 ), three rates of N fertilizer (0, 50 and 100 kg N ha-1 applied as urea), three rates of P fertilizer (0, 30 and 60 kg P ha-...

Effect of Oil Palm Cultivation on the Micronutrient Status of Soils in a Coastal Plain Sands Area of Akwa Ibom State, Nigeria

Chukwu E. D^*, B. T. Udoh, Nnabuihe, E, Okoli N. H, Osisi A. F

High levels of micronutrients may cause metabolic disorders and become growth inhibitors to most plant species. Therefore, the study assessed the levels of micronutrients in soils under oil palm cultivation in a coastal plain sands area of Akwa Ibom State, Nigeria. Three oil palm blocks of varying ages, l7 years (B-17), 39 years (B-39) and 57 years (B-57) and no oil palm block (B-O), which served ...
