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...
