Effect of Slope Positions on Properties of Soils of Some Forest Reserves in South - West Nigeria

Alabi, K. O.*

Topography has an influence on soil erosion and consequently on the properties of soils. The effect of slope position on soil properties is of great importance in soil suitability assessment. This study assessed the effect of topographic position on the characteristics of soil of basement complex rocks derived soils under Teak (Tectona grandis) and Gmelina (Gmelina arborea) plantations in Osun sac...

Characterization and Classification of Soils of Obukiyo, Oju Local Government Area of Benue State, Nigeria

Ogbu, O.J.*, Idoga S., Abagyeh S. O. I, Ugese, F.D, Usman, J.

Soils of Obukiyo, Oju Local Government Area of Benue State were studied using the grid method of soil survey with a view to characterize, classify and evaluate their potentials for sustainable crop production. Four soil units were identified on the field based on soil colour, texture, surface characteristics, topography and depth to water table. Two pits were sunk in each soil unit, described and ...

Degradation Effect of Palm Oil Mill Effluent (pome) on Physical and Chemical Properties of the Soils of Uga, South Eastern Nigeria.

Obiageli Patience Umeugochukwu*, V O Chude, Ezeaku P

This study investigated the impact of long term application of palm oil waste on the physical and chemical properties of sandy Ultisols (Arenic Kandiustult) in Uga, Nigeria. Soil samples were collected from the surface (0-10 cm) and subsurface (15-25cm) of the palm oil-polluted site. Another surface (0-10) and subsurface (15-25) samples were collected 15 meters away in the palm oil unpolluted (con...

Comparative Effect of NPK Fertilizer, Poultry Manure and Rice Mill Waste on Soil Chemical Properties, Nutrient Content and Performance of Ginger (zingiber Officinale Roscoe) in Umudike, Southeastern Nigeria

Okeke V. N.*, Nwangwu B.C

The study examined the comparative effect of NPK fertilizer, poultry manure and rice mill waste on soil chemical properties, nutrient content and performance of ginger in 2018 and 2019 at the National Root Crops Research Institute Farm, Umudike, Southeastern Nigeria, using ginger variety (UG 1) as the test crop. There were seven treatments consisting of sole and combinations of NPK15:15:15, poultr...

P Sorption Characteristics in Hevea Supporting Soils of Coastal Plain Sand Origin in Southern Nigeria

Idehen, C.N.*, Bakare, A.O., Okore, I.K, Osazee, F

Phosphorus (P) is a macronutrient element that plays a number of important roles in plants and soils including Hevea brasiliensis (Natural Rubber). Adequate P nutrition in rubber will result in improved latex production, crop quality, root growth and early maturation. Thus, a study of the relevant indicator of P sorption across depth of rubber supporting soils is necessary. Therefore, this study i...

Fertility Status of Biakpan Rubber (hevea Brasiliensis) Soils of Cross River State, Nigeria

Kekong, M. A.*

A study was carried out at Biakpan rubber estate in Cross River State, Nigeria to evaluate the fertility status of the soils. Three profile pits at random points within the estate were sunk representing the crest, the middle slope, and the valley bot- tom. Five samples were collected from each profile at 0 – 25cm, 25 – 50cm, 50 – 75cm, 75 – 110cm and 110 – 170cm depth. Fifteen representative soil ...

Yield Decline Trends of Eroded Ultisols in Owerri, Southeastern Nigeria: Maize Response to Artificial Erosion

Nnenna Nnannaya Oti*

The artificial incremental removal of surface soil to varying depths to simulate erosion followed by subsequent evaluation of crop growth and performance under uniform management is a common agronomic technique to study erosion/soil productivity relationships. However, because its results tend to exaggerate yield decline rates it is being replaced by the more complex erosion phase approach. This p...

Laboratory Incubation Studies of Biochar Amendment on Non - Co2 Greenhouse Gas Emissions from Soil Cultivated to Coconut Seedlings

M.O. Ekebafe*, P. Oviasogie, N.O. Asueni

Biochar is a carbon-rich product obtained when biomass such as wood, manure or leaves is heated in a closed vessel with little or no air. It is an appropriate tool for sequestrating carbon dioxide in soils for a long time in order to mitigate climate change. The objective was to determine the effects of biochar amendment on greenhouse gas emissions from soil cultivated to the coconut seedlings. Th...

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 ...
