Kinetics of Phosphorus Sorption in Selected Soils of Southeastern Nigeria

Azu, Donatus E.O*, V.E. Osodeke, Onwuka, M. I, Osisi A. F

This study investigated the phosphorus sorption kinetics of soils of varying parent material and soil depth in south east Nigeria. The parent materials studied were: Coastal Plain Sand, Basalt, Shale and Sandstone and the depths were: 0 – 20cm, 20-40cm and 40-60cm. Soil samples were collected from the different parent material in three replicates a...

Integrated Nutrient Application Effect on Npk Absorption and Root Yield of Sweet Potato (ipomoea Batatas (l) Lam) in a Tropical Ultisol

N. A. Onunka*, V.E. Osodeke, D. O. Asawalam, C. N. Ebeniro.

A field trial was conducted at National Root Crops Research Institute, Umudike, Abia State Nigeria, in 2004/2005 cropping seasons. The aim was to determine the effect of integration and time of application of two nutrient sources (poultry manure and inorganic fertilizer) on NPK absorption and root yield of sweet potato in an ultisol. Different rate...

Effect of Poultry Manure on Soil Chemical Properties and Root Yield of Sweet Potato (ipomoea Batatas (l) Lam) Grown in a Tropical Ultiso

N. A. Onunka*, V.E. Osodeke, D. O. Asawalam

A field trial was conducted at National Root Crops Research Institute Umudike in 2004/2005 cropping seasons. The aim was to evaluate the effect of poultry manure applied over time intervals on some soil chemical properties and root yield of Sweet potato. The time intervals were 2 weeks before planting, (WBP), at planting, 2, 4, and 6 weeks after pl...
