Comparative Effect of Variable Rates of Pig and Poultry Manure on the Agronomic Performances of Amaranthus Hybridus in Humid Rainforest South Western Nigeria

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

The health implication of deficiencies of vital nutrients could be supplemented by taking vegetable which are highly nutritious and easily affordable. An experiment was conducted at the Teaching and Research Farm of the Lagos State Polytechnic, Ikorodu, Nigeria, to evaluate the comparative effects of different levels of animal manure on the growth and yield of Amaranthus hybridus. Pig dung (PD) an...

Impact of Mining on Heavy Metal Concentration and Soil Chemical Properties in Soils Sorrounding a Mining Site in Ebonyi State⸴ Nigeria

Akinmutimi A.L.*, OlughuF.N., Nwangwu B.C

Field and laboratory studies were done to evaluate the effect of land use types on selected physical and chemical properties of soils in Umudike, southeastern Nigeria. Five land use types were studied: rubber plantation, oil palm plantation, forest land, cassava farm land and pasture land. Under each land use system, 3 sampling points were located. Around each of the 3 sampling points, soil sample...

Effects of Parent Material and Land Use on the Variability of Available Cu in a Wetland Soil Under Long - Term Farming System

Eteng, E.U.*

The study was carried out in the dry season to evaluate the variation in available Cu in wetland soil under long-term farming systems. Twenty four surface (0-20 cm) composite soil samples of acidic nature were obtained and analyzed for available Cu in the soils using five extractants (0.01M HCl, Coca-cola, 0.05M EDTA, 0.05M DTPA, and 1N NH4OAc) respectively. Some important soil char-acteristics li...

Mineralogical Investigation of Some Imperfectly and Poorly Drained Soils of the Nigerian Northern Guinea Savanna Agroecology

Abdulrashid Shobayo Babatunde*, Sulaiman Yau Lawan, Aliyu, J.,

This study aimed to investigate the mineralogy of soils with impaired drainage formed within the northern guinea savanna of Nigeria. Soil survey procedure was carried out to identify the two soil individuals (polypedon) namely: imperfectly drained soil (IDS) and poorly drained soil (PDS) that occupied 6,407.68ha (90.96%) and 636.82 ha(9.04%) respectively. In each soil individual, a repre- sentativ...

Variability of Some Properties of the Nun River Plain Soils in Bayelsa State, Nigeria

Achimota A. Dickson*, Tate, J. O, Ogboin, P. T, Payebo, O. C, Agbai, W. P.

Whereas studies on spatial variability of soil properties on toposequences are well documented, information on the variability of characteristics of floodplain soils is lacking. This study, therefore, evaluates the status and variability of the soil properties in three physiographic units in two locations on the Nun River floodplain. Silt-sized particles dominated soil texture and soil texture var...

Hydro - Geomorphic Study on Selected Soil Properties, Classification and Management Considerations of Soils on Alluvial Landforms in Southeastern Nigeria

Umeugochukwu O.P*, Akamigbo, F.O.R., Chude, V.O, Eze P.N

The soils were characterized with regards to their macro morphology, physicochemical properties and heavy metal contents. This is to infer their pedogenesis and propose agrotechnology transfers as well as management considerations necessary for sustainable cultivation. Reconnaissance survey was used for initial soil identification. Two categories of the flood plain soils were identified viz. the l...

Fertility Baseline Study of Major Cocoa Growing Soils of Nigeriaand Implication for Cocoa Production in Nigeria

AJIBOYE G. A.*, Jaiyeoba, J. O., Olaiya, A. O., Hammed L. A.

"Field and laboratory studies were conducted to evaluate the fertility status of the soils of three major cocoa-producing States in Nigeria. A Survey of the selected Local Government Areas was carried out and soil samples were collected at 0-30 and 31-60 cm depths. The Physico-chemical properties of the soils were assessed in relation to cocoa nutritional requirements using standard methods while ...

Effects of Organo-Mineral Fertilizer and Cocoa Pod Husk Ash on the Soil, Leaf Chemical Composition and Growth of Coffee

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 ...
