Effect of Land - Use on Particulate Organic Carbon and Carbohydrates Distributions in Dry - and Wet - Sieved Stable Aggregates in an Ultisol

Udom B. E.*, Simon U. G.

Particulate organic carbon (POC) and carbohydrates (R-CHO) distributions in dry- and wet-sieved aggregates in four land-use types in southern Nigeria were studied. The land-use types were: secondary forest, 5-year fallow plots, cocoa plantation, and 5-year continuous cultivation. The results showed that land types affected soil organic carbon fract...

Effect of Tillage and Maize - Cowpea Intercrop on Fractal Features of Particle and Aggregate Size Distribution on a Tropical Sandy Loam Soil in Southwest Nigeria

ADESODUN Johnson Kayode*, Udom B. E., Adekunle A. O, Adejuyigbe C. O.,, Atayese M. O., Olowokere F. A., Mbila M., Oyegoke, C.O,

The effects of tillage and cropping pattern on soil aggregation, fractal dimensions and distribution of organic carbon fractions were studied. Treatments were no- tillage (NT), conventional tillage (CT), and four cropping patterns viz: sole maize, sole cowpea, maize-cowpea intercrops and control (no crop). Soil samples were analysed for particle si...

Soil Organic Carbon Fractions and Aggregation of a Tropical Alfisol as Affected by Plant Residues

ADESODUN Johnson Kayode*, Udom B. E., Abudu O. S., Adejuyigbe C. O.,, Enikuomehin O. A, Thannia B. M, Oke O. O., Olowokere F. A., Oyegoke, C.O,, Mbila M.

Incorporation of plant residues into soil plays a vital role in enhancing the quality of fragile tropical soils. This study evaluated the short-term effect of plant residues of different quality on organic carbon (OC) fractions, carbon management indices and stability of a sandy loam soil with low (< 2%) initial OC content. The residues are Banana ...

Micro - Aggregate Indices and Structural Stability of Soils Under Different Management

Udom B. E.*, Anozie H.

Low water stability of soil micro-aggregates accentuated by increased intensity of cultivation and soil degradation are among the significant issues that draw the attention of Soil Scientists due to their effects on soil physical conditions. The study was carried out to quantify changes in micro-aggregate stability indices of soils on coastal plain...

Contaminant Limit (c/p Index) of Heavy Metals in Spent Oil Contaminated Soil Bioremediated with Legume Plants and Organic Nutrient

Udom B. E.*, Ano, A. O., Chukwu L. I.

Three legume plants (Gliricidia sepium, Leucaena luecocephala and Calapogonium caerulean) alone or in combination with 0.5% (w/w) poultry manure were tested for their ability to reduce the heavy metals and toxicity criteria of a sandy soil contaminated with 5% (w/w), (equivalent of 50,000 mg/kg) spent lubricating oil, each for two years. The oil an...
