Influence of Land Use on Soil Physiochemical Properties in Semi - Humid Nsukka Area of Southeast - Ern Nigeria

Umeobi E. C^*, , Ezeaku, P.I., Umeugokwe C. P, Ezeaku, V. I

The influence of four land uses (cultivated arable land, grassland, oil palm planta- tion and rubber plantation) on physical and chemical properties of coarse- textured acid soils was assessed in the semi-humid Nsukka area. Soil auger and core samples were used to achieve surface sampling at the depth intervals of 0-20 and 20-40cm in each land use ...

Characterization and Identification of Contemporary Diagnostic (b) Horizons of Some Soils in Ideato North Local Government Area of Imo State Southeastern Nigeria

Onyekanne, C. F.^*, Uzoh I .N, , Ezeaku, P.I., Akamigbo, F.O.R.

Most soils in Nigeria have not been characterized and classified based on diag- nostic B horizon and identification of diagnostic B horizon is essential in the study of soils. As a result, this study was carried out to characterize and classify these soils with special emphasis on the identification of diagnostic B- horizons. A free survey method w...

Variability of Micronutrient Status and Hazard Potential in Soils of Six Mapping Units Within Eastern Part of Kogi State, Nigeria

Ukabiala, M.E, Uzoh I .N^*, Kolo J., , Ezeaku, P.I., Akamigbo, F.O.R.

Micronutrient imbalance in some soils is a major challenge for cultivation of crops. Hence the need to assess their status and variability in agricultural soils. The aim of this research was to assess the micro-nutrient status, variability and hazard potential in some soils within eastern part of kogi state of Nigeria. Six mapping units, 2a, 17a, 1...

Influence of Forms of Iron and Manganese Oxides on the Physical and Chemical Properties of Soils Formed Over Mica - Schist in a Northern Guinea Savanna, Nigeria

Kefas, P. K^*, Abdulrashid Shobayo Babatunde, Ofem, K.I, Akwoga, J.A, Asadu Charles Livinus, , Ezeaku, P.I.

Three forms of oxides of iron and manganese were evaluated on soils developed in mica-schist lithology within the basement complex formation of Taraba State, North-eastern Nigeria. The results from the three oxide forms namely, pyrophos- phate extractable (Mnp/Fep), oxalate extractable (Mnox/Feox) and citrate- bicarbonate-dithionite extractable (Mn...

Suitability of Urban Waste Land Use in Relation to Heavy Metal and Micronutrient Influence on Soil and Green Amaranth Production in Southeast Nigeria

Ezeifeka A.O^*, , Ezeaku, P.I., Ezeaku, V. I, Anikwe M. A. N, Kefas, P. K, Ofem, K.I

An assessment of the impact of long term (>20 years) MSW disposal on soil properties and their suitability for crop productivity was carried out in Anambra and Enugu States of southeast Nigeria. Four dumpsites were selected (two in each state) and, 12 soil auger samples (2 sampling points at 3 depths and 2 repeated measures) each were collected at ...

Influence of Granulometric Composition and Organic Matter Management on Soil Stability Against Water Erosion in Southeastern Nigeria

Ezeaku, V. I^*, Sunday Ewele OBALUM, , Ezeaku, P.I., Igwe C. A

The study investigated the influence of granulometric composition and organic matter on soil stability and eroded sediment under simulated rainfall for some soils from southeastern Nigeria. The experiment was conducted at the Glasshouse of the Department of Soil Science, University of Nigeria Nsukka (UNN). The experimental design was a 3 x 3 factor...

Land Suitability Evaluation for Maize Production and Taxonomic Classification of Soils Overlying Undifferentiated Basement Complex in Northeast Nigeria

Kefas, P. K^*, Maigida, E, , Ezeaku, P.I., Ofem, K.I, Akwoga, J.A, Ezeaku P

Soil characterization, classification and evaluation provide useful information for the understanding of its different facets, hence their potentials and limitations for crop production. Such information is lacking in the general area of Kona-Jalingo in Taraba State, Nigeria, hence the study to determine the macro-morphological, physical and chemic...

Impact of Open Cast Mine Land Use on Soil Physical Properties in Enyigba, Southeastern Nigeraand the Implication for Sustainable Land Use Management

Okolo, C.C.^*, Akamigbo, F.O.R., , Ezeaku, P.I., Nwite, J.N, Nwite, J.C, Ezeudo, V. C, Ene, J., Ukaegbu, E. P, Udegbunam, O.N., Eze, N. C

The study examined the extent of soil physical properties deterioration due to mining activities in Enyiba Ebonyi State, Southeastern Nigeria. In the study, two factors were considered: factor A - Soil depths (surface soil: 0-15 cm and subsurface soil: 15-30 cm) and factor B - Distances from mine pits (100 m, 200 m, 300 m, 400 m and 500 m away from...
