Adejobi K.B*, Famaye, A. O., Oloyede A.A., Oyedokun A.V, Adeosun S.A, Adeniyi D.O.

A nursery experiment was carried out in Ibadan (rain forest zone), Southwest Nigeria to study relative effect(s) of combined use of organo-mineral fertilizer (OMF) and cocoa pod husk ash (CPHA) on soil chemical properties, nutrient status and growth of coffee seedlings (Coffea arabica L.). Eight treatments: 5t/ha CPHA, 20 t /ha OMF, 20 t/ha OMF + 5t/ha CPHA, 15 t/ha OMF + 5 t/ha CPHA, 10t /ha OMF ...

Physical and Chemical Properties of Soils in Kogi State, Guinea Savanna of Nigeria

S.O. Amhakhian*, I.O. Osemwota

This experiment was conducted in Kogi State. Twenty composite surface soil samples (0.15cm depth) drawn from two distinct geological formations (Cretaceous sediments and Basement complex) were used for the study. These soils were collected from different sites with varying cropping history. Particle size analysis of the soils used indicated a high proportion of sand, the texture of the soils range...

oil Microbial Activity Under Complementary Applications of Organic and Inorganic Amendments

Sangotoye S. E.*, Atere C. T., Taiwo, L. B, Olayinka A.

The research described and quantified soil consistency as cumulative consistency value (CCV) at two moisture levels for different horizons of soil profiles located on sedimentary and basement complex parent materials. It was found that the CCVs of soils formed on sedimentary deposits were between 18 and 28 while the CCVs for the soils formed on the basement complex were between 0 and 27. No signif...

Assessment of the Effect of Abattoir Effluent on Soil Properties Cultivated with Flint Maize

Abhanzioya, M. I.*, James, T .V

The assessment of abattoir effluent on the physicochemical and microbiological properties of the soil cultivated with flint maize was conducted in the Teaching and Research Farm of Ambrose Alli University, Ekpoma. The experiment was a randomized complete block design (RCBD) with five levels of abattoir effluent (0, 32 x 103, 64 x 10 3, 96 x 103, 128 x 103L/ha) and each was replicated three times. ...

Effect of Water Hyacinth (eichhornia Crasspies) Manure on the Performances and Yield of Okra (abelmoschus Esculentus) (l.)moench

Sanni K. O.*, Adesina J. M., Ewulo B. S.

Water hyacinth is one of the most economically damaging weeds and all efforts to control it met with little success. An experiment was conducted during the 2011 cropping season at Lagos State Polytechnic, Ikorodu, Lagos State, to evaluate the effects of manure produced from water hyacinth on the growth and yield of okra. There were three (3) treatments: 0.9 kg, 1.35 kg of water hyacinth manure per...

Heavy Metal Pollution of Dumpsite Soil of Kogi State University, Ayangba

Agboola K.*, Wahab A. A., Aina O. A, Ameh E. A

The research aims to assess the local addition of selected heavy metals (Pb, Cd, and Cu) when dumpsite soil is used as a soil amendment and the ability of Amaranth (NH536–1) to phytoremediate the soil. It was a pot experiment conducted at Kogi State University's Faculty of Agriculture in Ayangba. The soil samples were collected from a dumpsite and arable soil. The dumpsite soil application to the ...

Soils and Urban Land Use Planning: a Case Study of Makurdi Urban Centre, Benue State of Nigeria

S. IDOGA*

Frequent cases of human displacement, loss of properties and sometimes lives caused by seasonal floods in Makurdi Urban Centre in recent times necessitated a pedological investigation on the soils of the town. Six soil profile pits were sunk in selected areas of Makurdi, two in the high lying area of Makurdi North Bank and four others in the low lying areas of the South Bank settlement. The invest...
