Pedological Characterization and Classification of Soils Underlain by Basement Complex at the Mambilla Plateau, Nigeria

Osujieke D.N.*, Idoga S., Abagyeh S. O. I, Ugese, F.D

The study aimed to characterize and classify selected soils underlain by a basement complex at the Mambilla Plateau in Taraba State Northeast, Nigeria. A total of 12 pedons were dug to represent sampling units. Soil samples from the pedogenetic horizons of the pedons were collected after profile description, processed and analyzed. The pedons were very deep (> 150 cm) except for pedon 3, which was...

Comparative Yield of Bell Pepper (capsicum Annuum L.) on Different Soil Series in Ibadan, Southwestern Nigeria

Olufunmi O. O.*, Adeoye G. O

Climatic change and its accompanying adverse effects on the cultivation of crops such as bell pepper - an important fruit vegetable requires adaptable technology strategy at low or no cost to poor resource farmers. Growing bell pepper on soils considered less suitable could be an adaptation strategy to mitigate the effect of climate change on bell pepper production. Field trials were conducted at ...

Seasonal and Fertiliser Effect on the Yield of Bell Pepper (capsicum Annuum L.) in Ibadan, South Western Nigeria

Olufunmi O. O.*, Adeoye G. O

Emerging supply crisis in the food chain of crops such as Bell pepper (Capsicum annuum L.) from traditionally major producing areas of Southern and Northern guinea savannah of Nigeria to other parts of the country makes it expedient to cultivate the crop under different weather conditions and fertiliser requirements. Field trials were conducted in Ibadan, South western Nigeria (derived savannah ag...

Evaluation of Npk Fertilizer Formulations on the Growth and Dry Matter Yield of Coffee Seedlings

Ibiremo, O.S.,*, AKANBI Olorunfemi Sunday Ojo, Oloyede A.A., Adebowale L.A

A greenhouse study was carried out at Cocoa Research Institute of Nigeria, Ibadan to evaluate the effect of NPK fertilizer formulations on the growth and dry matter yield of coffee seedlings. The treatments consisted of NUTRICO-1 (NPK-liquid fertilizer) applied at rate 5 and 10 ml/15L water) and NPK- solid fertilizer 15:15:15 applied at 1, 3 and 5g/coffee seedling and a control. Data on growth of ...

Micronutrient Status of Grain Size Fractions in Soils of Land Uses in Mbano, Southeastern, Nigeria

Bethel Ugochukwu Uzoho*, Irokwe I. F.

Micronutrient status in grain size fractions provides information on the active soil fraction and the ability for stabilization against microbial decomposition. Total, available, exchangeable and water-soluble Fe, Zn,Cu and Mn in bulk and grain size soil fractions were evaluated in three landuse types (Cassava, Cashew and Oil palm) in Ehime Mbano, Southeastern, Nigeria. Also, selected soil propert...

Characterization, Land Capability and Fertility Classification of Soils Along Kpantinapu - Nukkai Toposequence in Jalingo, Taraba State

Gisilanbe Solomon Adamu*, Hashim, S.A.,, Garpiya B. T, Kussiy J. J, Ibrahim I. S

The objective of this study was to characterize the soils of the study area, deter- mine some soil properties and classify the soils according to USDA Taxonomic System. Coordinates of the Pedons were obtained using hand held Geographic Positioning System (GIS) and one (1) profile pit was dug at the upper, middle and lower slope respectively. Some soil physical and chemical properties were deter- m...

Effect of Integrated Application of Soil Amendments on Nutrient Uptake and Soil Properties in a Tropical Alfisol

Amusan A. O*, OJENIYI STEPHEN OLUSOLA

A field experiment was conducted on a tropical alfisol for two consecutive years to determine the effect of integrated application of nutrient sources on nutrient uptake and soil properties. The treatments consisted of two rates of poultry manure (0 and 5 t ha-1 ), three rates of N fertilizer (0, 50 and 100 kg N ha-1 applied as urea), three rates of P fertilizer (0, 30 and 60 kg P ha-1 applied as ...

Soil Suitability Evaluation for Maize in Lere Local Government Area of Kaduna State Nigeria

Magaji M. J*, Samndi M. A., Ado A A, Ibrahim Babagana Buji, Abubakar M. A.

The soils of Lere (Saminaka) in Kaduna state, Northern Guinea Savanna climatic zone were evaluated for suitability of maize (Zea mays) cultivation, employing various methods. Data were obtained through field study and laboratory analyses. Three soil Units were delineated, and one profile was sunk in each of the soil units. The profiles were described according to the USDA soil survey manual, and s...
