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...

Response of Soil Sustainability Indicators to the Changing Weather Patterns in Calabar, Southern Nigeria

Okon, P. B.^*, Nwosu, N. J., Isong, I. A.

The response of soil properties to changing weather variables revealed soil-environment functionality that is used to know whether soil quality is improving, remain constant or declining. This paper investigates the effects of weather variables (temperature, relative humidity, and rainfall) on soil quality and sustainability and its agro-meteorological implications. Soil samples were collected fro...

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 B.M, 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 20 m and at depths of 0 to 15cm and 15 to 30 cm, parceled, labeled and taken to the...

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

Senjobi B.A.^*, 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...
