Effect of Land Use and Soil Depth on Soil Phosphorus Fractions

Jamiu Oladipupo Azeez^*, Aloba F. O, Ogunwale O. V, Oguntade O. A., Adekunle. I. O, Amusan A. O

The aims of the experiments were to determine the effect of land use and soil depths on soil phosphorus fractions. Soil samples were taken systematically from dug profile pits at 0-20, 20-40 and 40-60 cm. Soil samples were characterized and P fractionation analyses were done in triplicates using standard procedures. Data generated were analysed usi...

Effect of Integrated Application of Soil Amendments on Nutrient Uptake and Soil Properties in a Tropical Alfisol

Amusan O. A.^*, OJENIYI STEPHEN OLUSOLA

A field experiment was conducted on a tropical alfisol for two consecutive years to determine the effect of integrated application of nutrient sources on nutrient uptake and soil properties. 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 o...

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), ...
