Effects of Land Use on Forms of Phosphorus in Coastal Plain Sands of Nigeria

Obi J. C.,*, Ibia, T. O, Ikott, I. E.

This research studied the effect of land uses changes on the forms of phosphorus within the coastal plain sands landscape of southeastern Nigeria. Satellite imageries and soil data including phosphorus fractions were used for the study. Spatial coverage of forest and agricultural (fallow and farmland) land uses, accompanying soil properties and forms of phosphorus were estimated. There was progres...

Tillage and Residual Effect of Some Organic Amendments on Aggregate Associated Soil Carbon of an Ultisol, Growth and Yield of Maize and Cowpea Intercrop

Onunwa A.O.*, Igwe C. A, Mbonu O. A

associated soil carbon (C WSA) and yield of maize and cowpea intercrop in an Ultisol, Southeastern Nigeria. A land area of 0.1125 ha was planted to sole cowpea, sole maize and maize-cowpea intercrop using minimum tillage (NT) and conventional tillage (CT) with poultry droppings (PD), pig waste (PW), and Cassava peels (CP) as amendments at the rates of 20, 90, 100 t/ha respectively and a co...

Phosphorus Status in Some Soils of Mid - Western Agro - Ecological Zone of Nigeria

Orhue, Ehi Robert*, John Kingsley

The trial was carried out to determine the status of various forms of P in soils formed on 3 types of parent materials in Southern Nigeria. Soil samples were obtained from3 ha area in each of the locations at 0-15 cm and 15-30 cm depth and then subjected to routine physical and chemical analysis. Results revealed that the sand component of the soils which ranged from 771 gkg-1 to 892 gkg-1 decreas...

Physical and Chemical Characterization of Some Selected Soils in University of Maiduguri, Borno State Nigeria

Ibrahim Babagana Buji*, Adamu I., Magaji M J, Hayatu N. G, Zubairu A M, Hannatu J., Murtala Bawa Sharu

A semi-detailed survey was conducted to characterize some physical and chemi- cal properties of soils of Teaching and Research Farm University of Maiduguri, Borno State. Three sites were selected on the basis of land forms and surface tex- ture and their description were taken using two soil profile pits at each sites. The soils collected were subjected to laboratory analysis using standard proced...

Soil Mapping, Classification and Morphological Characteristics of the University of Benin Land

Okunsebor, F.E.*, Umweni A. S.

This study was conducted to map, and classify the soils of University of Benin Teaching, Research and Integrated Farm site. Rigid grid soil survey method at an intensive scale was done on a 62-hectare land that produced seven mapping units. In each mapping unit, a representative pedon was sunk, described and sampled. Soil samples were analyzed using standard methods. Data generated were ana- lyzed...

Classification of the Obudu Plateau (crest) and Sub Plateau Soils of Cross River State, Nigeria.

Essok A. N.*, Essoka, P.A

The soils at the plateau (crest) and sub plateau of three ranges of Obudu mountains were studied using profiles. Two profiles each were dug at the Ranch, Belinge and Belegate. These six profiles were studied morphologically and physicochemically; and the result used for (USDA and FAO) classification. The plateau and sub plateau soils of the Ranch and Belinge possessed mollic A epipedons and argill...

Land Suitability Evaluation for the Production of Maize (zea Mays) and Groundnut (arachis Hypogaea L.) Using Parametric and Non - Parametric Methods in Mambilla Plateau, Nigeria

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

The study aimed to evaluate the land suitability for the production of maize (Zea mays) and groundnut (Arachis hypogaea L.) in selected soils of the Mambilla Plateau in Sardauna local government area in Taraba State Northeast, Nigeria. Land suitability for maize and groundnut production was evaluated both by the conventional (non-parametric) and parametric methods. A total of 12 pedons were dug to...

Soil structure stability and organic carbon distribution along the toposequence of Orumba North in derived savannah of the South-East, Nigeria

Jidere, C.M.*, Ezeokoye, C.S., Obalum, S.E., Ukaegbu, E. P

In high-rainfall zones with severe water erosion problems, soil structure stability as promoted by soil organic carbon (SOC) should be prioritized. Landscape positions and land use influence soil properties and nutrient distribution. This study assessed soil structure stability and SOC content at top-slope, mid-slope and low-slope positions of a toposequence at Orumba North in derived savannah zon...

Effect of Simulated Acid Rain on Growth and Micronutrient Uptake of Okra (abelmoschus Esculentus) on Coastal Plain Sands in Abia State, South - Eastern, Nigeria

Eteng, E.U.*, Essien G. E

The study was conducted in April 2019 at Umudike to examine the impact of simulated acid rain (SAR) and frequency of SAR spray on growth and micronutrients content of okra (Abelmoschus esculentus (L.) Moench) in an ultisol at Umudike. The treatments consisted of three (3) pH levels: Coca-cola solution (pH 2.7) and SAR (pH 3.5 and 5.5) as well as control (water) and, three (3) frequency of foliar s...

Simulating Soil Nutrients Balance Using Monqi Model (monitoring for Quality Improvement) in a Rice Based Cropping System of Kano State, Nigeria

Abdulrahman B. L.*

Enhancing soil microbial properties through balanced inputs of organic and inorganic amendments are key to sustainable soil and crop productivity. A laboratory incubation study was conducted to determine microbial respiration, population and nutrient (N and P) mineralization patterns in an Ultisol amended with sole Urea at 56 kg N ha−1 or Urea (at 0 or 28 kg N ha−1) combined with 5 t ha−1 organic ...
