Effect of Trichoderma Inoculated Organic Manure on Water Retention Characteristics of Two Texturally Contrasting Soils in Nsukka, Southeastern, Nigeria

Azuka, C.V.*, Oka, S. C

The effect of Trichoderma inoculated organic manure on water retention charac- teristics of two texturally contrasting soils was investigated in the glasshouse of the Department of Soil Science, University of Nigeria, Nsukka. The study in- volved two texturally contrasting soils, sandy loam (SL) and loamy sand (LS) amended with poultry manure (PM) at three rates (10 t/ha, 20 t/ha and 30 t/ha) and ...

Influence of Soil Amendment with Poultry Droppings on the Soil Properties and Productivity of Cucumbers (cucumis Sativus L.) on a Degraded Ultisol in Nsukka Area, Southeast Nigeria

Okebalama C.B*, Ogunezi K.C, Agbo I.C, Asogwa K C

Poultry manure (PM) input is globally utilized for enhancing and maintaining soil fertility in vegetable farming. In many tropical regions, however, ‘site’ specific PM rate for optimum crop yield is lacking. A three-year continuous cucumber cultivation with 0, 10, 20 and 30 t/ha PM rates in three replicates, were arranged in RCBD on an Ultisol. Soil physicochemical properties and cucumber yield re...

Effects of Litter Quality and Decomposition Rate of Some Agroforestry Species on Soil Properties in Rivers State University Campus

Mgbonu Kelechi*, Zarma Adamu, Ogori Joeguluba, Wenibo Andrew

The effect of litter quality and decomposition rate of some agroforestry species on soil properties found in the main campus of Rivers State University, Port Harcourt, Nigeria was investigated. Litters from Masquerade tree, gmelina and teak were collected and their chemical composition determined. Twenty-five grams (25 g) of each leaf litter was placed in a nylon litter bag and buried shallowly wi...

Decomposition of Entandrophragma Cylindricum Tree Prunings in Agroforestry System in Onne, Rivers State

Koyejo, A.O*, Koyejo, O.A, Olatidoye, O.R, Adetunji, A.S.

A study was conducted at Swamp Forest Research Station, Onne, Forestry Research Institute of Nigeria, to evaluate the rate of decomposition of E. cylindricum tree prunings. The experiment was a 2x8 factorial in a randomized complete block design with three replications. The first factor comprises two placement methods (surface-placed and soil-incorporated) and the second factor comprises eight biw...

Effects of Different Land Uses on Soil Quality and Degradation in Abeokuta, Ogun State, Nigeria

Basil E.C.*, Senjobi B.A., Oyegoke, C.O,, Fabunmi, T.O.

A detailed soil survey was carried out at the Teaching and Research Farms of Federal University of Agriculture, Abeokuta. The study aimed to determine the effects of different land-use types on some soil quality indicators and to examine the relationship among the land use types, soil quality indicators, and land degradation. Surface (0-15cm) and sub-surface (15-30 cm) soil samples were taken from...

Evaluation and Classification of Soil Fertility Potentials of Gombi Area of Adamawa State, Northeastern Nigeria

Johnson, A., Saddiq A. M., Solomon, R. I*, Ibrahim, A., Waizah, Y

A study was conducted to evaluate the soil fertility potential of Gombi area of Adamawa State, Nigeria. A total of eighty (80) soil samples composite from 0-20 and 20-50cm depths were collected from selected representative locations from the ten (10) wards of the study area and analyzed using standard laboratory procedures. Results obtained revealed that the texture of the soil ranged from sandy l...

Characterization and Taxonomic Classification of Some Basement Complex Soils in Kwara State

Bashiru Ademola Raji*

The soils of the Oyun Local Government Area of Kwara State were studied with the aim of characterizing and classifying them to provide the needed inputs into the Agricultural Transformation Agenda of the Government. Six soil mapping units were identified and designated YN1, YN2, YN3, YN4, YN5 and YN6. The soils were all formed on basement complex rocks, had deep weathered pedons and lateritic laye...
