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 ...

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...
