Variability of Some Soil Properties Along a Toposequence in a Basaltic Parent Material of Vom, Plateau State Nigeria

Mahmud A. T.^*, Hassan I.M, SHEHU Bello Muhammad, Samndi M. A.

Topography influences the distribution of some soil physical and chemical properties. This study assessed some variation in soil properties resulting from the topographic effect on Basaltic parent material at Vom Jos Plateau State in the Southern Guinea zone of Nigeria. Soil samples were collected at an interval of 20m and at depths of 0 to15cm and 15 to 30cm, parcelled, labelled and taken to the ...

Characterization and Classification of Soils of a Toposequence at Osun Sacred Grove, Nigeria

Bolarinwa Ayoola Senjobi^*, Alabi K. O., AJIBOYE G. A., Adeofun C.O.

Rational use of forest resources without accurate knowledge of land and soil properties is a primary concern in achieving any millennium goal on afforestation. Hence, the morphological, physical and chemical properties of soils of a toposequence over coarse-grained granite gneiss at Osun sacred grove, in Osun State, south-Western Nigeria were studied. Three profile pits were dug under each land-us...

Characteristics of Soils Along a Toposequence in Ishiagu, Eastern Nigeria and Its Relation to Potential Agricultural Landuse.

Nsor M.E.^*, Adesemuyi, Emmanuel Adeboye

The soil along a toposequence in Isiagu, Eastern Nigeria was studied to establish its influence on soil properties and its relation to potential agricultural use. In order to characterize and classify the soil, three pedons were dug along the toposequence at the crest, middle slope and valley bottom. The soils were characterized in terms of their morphological, physical and chemical properties. Th...

Effects of Phosphorus on the Phenological Traits of Maize (zea Mays) in Yola North Eastern Nigeria.

Kwaghe, E.J.^*, Gungula, D

This study was conducted during the 2000 and 2001 cropping seasons at the University Research Farm, Federal Universality of Technology, Yola to evaluate the effects of phosphorus on the phenological traits of maize (New Kaduna White) hybrid variety. There were eight treatments consisting of four levels of N, 0, 60, 120 and 180kgNha-1 and two levels of P, 0 and 60kgPha-1, replicated three times. Th...

Land Suitability Evaluation and Management of Ultisols for Some Tree Crops Cultivation in South South Nigeria

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

A rigid grid soil survey was done on 115.5 hectares of land in Ultisols of South Southern Nigeria at a detailed scale to evaluate its suitability for the cultivation of some tree crops (Cocoa, Plantain, Cashew, Pawpaw and citrus). Mapping units were delineated on the basis of morphological characteristics examined at 100 m along traverses which were cut at intervals of 100 m from a predetermined b...

Impact of Composted Oil Palm Wastes on Soil Physical Properties, Organic Matter Content and Growth of Oil Palm Seedlings Under Different Moisture Regimes

Ovie S.^*, Anisiobi, G.E., Okolo, C.C., Udegbunam, O.N., Okenmuo, F.C.

A greenhouse study was conducted at the University of Nigeria, Nsukka, to evaluate the effect of composted oil palm bunch waste for improvement of some soil physical properties, organic matter status and growth of oil palm seedlings under different water management conditions. The experiment was a 4 x 3 factorial fitted into the completely randomized design with three replications. It consisted of...

Ammonium, Phosphate and Potassium Sorption Studies on Peat and Mineral Soils

ADEBIYI O.V^*, ZAHARAH, A.R., Agbede O. O.

The previous field trials on Sago palm cultivation in Malaysian peat under Nitrogen (N), Phosphorus (P) and Potassium (K) fertilizers application failed to produce a positive growth response. Consequently, the comparative studies reported herein were carried out on peat and mineral soils, both strongly acidic (pH

Microaggregate Stability and Organic Carbon Fractions of a Tropical Loamy Sand Amended with Pig-Composted Manure

ADESODUN Johnson Kayode^*, O. S. Adekonojo

Soil organic carbon (SOC) is important in restoration of microaggregate stability of tropical soils. This study evaluated effect of pig-composted manure applied at 0, 5, 10 and 15 Mg ha-1 to cultivated land and forest re-growth land on distribution of organic carbon (OC) fractions and microaggregate stability using principal component analysis (PCA). The cultivated land was planted with two variet...

Evaluation of Infiltration Models in Soils of Two Land Use Systems in Calabar, Nigeria

Isong I. A.^*, Ogban P. I., Antigha, N.R.B., Okon, P. B.

Recently, the importance of the infiltration process in agriculture and the environment has resulted in an upsurge of interest by soil and water scientists to model the process for quantitative application. A study was conducted on the University of Calabar Teaching and Research Farm, Calabar to evaluate the effect of oil palm (OP) and arable farm (AF) land use systems on the Green-Ampt (GA), Phil...

Characterisation and Fertility Capability Status of Alfisols Under Different Land Uses in Ogun State, South Western Nigeria

Bolarinwa Ayoola Senjobi^*, Ande Olufunmilayo Titilayo, Ogunkunle A. O.

This study was designed to assess the fertility potential of agricultural soils for optimal and sustainable production. Soils under five land uses were characterized and evaluated for fertility status using Fertility Capability Classification (FCC) systems. The results showed that the morphology, physical, and chemical properties of the soils varied from one land type to another in all the five la...
