Kayode C.O.^*, Akande M. O., Adeoye G. O, Adekunle A. F., Ogunleti D. A.

A pot experiment was conducted at the Screen house of Federal College of Agriculture, Ibadan to investigate the effect of composts on the growth, nutrient uptake and dry matter yield of Roselle. Three types of compost were produced from cocoa pod husk (CPH), neem leaf (NL) and poultry manure (PM) namely CPH + NL + PM, CPH + NL and CPH + PM. There were fourteen treatments with three replications. T...

Characterization of Organic Carbon Fractions in a Southwestern Nigerian Soil: an Acid Hydrolysis Approach

S. J. Akinsete^*, O. F. Adebayoa, J. I. Uponib

Soil organic carbon characterization using acid hydrolysis is commonly performed at high temperatures but rarely at room temperature. This study used acid hydrolysis at 95 ºC and 25 ºC to quantify recalcitrant (non-hydrolyzable carbon, NHC) and labile C fractions of three depths in a planted fallow (Mucuna jaspedea) soil. Across depths, SOC fractions were: total SOC (11.83 – 21.57 g kg-1) > NHC 25...

Classification of the Obudu Plateau (crest) and Sub Plateau Soils of Cross River State, Nigeria.

Essok A. N.^*, Essoka, P.A

The soils at the plateau (crest) and sub plateau of three ranges of Obudu mountains were studied using profiles. Two profiles each were dug at the Ranch, Belinge and Belegate. These six profiles were studied morphologically and physicochemically; and the result used for (USDA and FAO) classification. The plateau and sub plateau soils of the Ranch and Belinge possessed mollic A epipedons and argill...

Combined and Sole Application of Compost and Npk Effect on Okra Yield, Soil and Nutrient Content

Law-ogbomo K.E^*, OJENIYI STEPHEN OLUSOLA

An on-farm experiment was conducted at Uyinmwendin, Edo State, Nigeria in 2009 and 2010 to study immediate and residual effect of compost alone or combined with NPK fertilizer (NPK) on okra (Abelmoschus esculentus) and nutrient availability. Five treatments applied to okra on ultisol of Benin formation were a control, compost (CM) at 20 and 40 t ha-1, NPK 200 kg ha-1, 20 t ha-1 CM + NPK 100 kg ha-...
