“…The 95% confidence interval for mean organic matter generally ranged from 0.79 to 2.55% and 0.35 to 1.31 in the A and B horizons respectively.

Okusami et al (1997) noted for some basement complex soils that organic carbon followed a systematic decrease with depth.…”

Information on the chemical characteristics of soils is required in the sustainable the management of soil fertility and productivity. The objective of this study was to determine chemical characteristics of basement complex derived soils of the Jos Plateau. Soil study followed the approach in the Soil Survey manual and began by identification of three geologic units: granite gneiss, biotite granite and migmatite. Furthermore, eighteen soil profile pits were dug in each geologic units and eighty-four samples were taken from genetic horizons. Standard laboratory procedures were used to analyze soil samples for pH, organic matter, nitrogen and phosphorus. Results showed that organic matter contents in the soils were generally low and seemed to influence the distribution of nitrogen in the soils. Consequently, contents of total nitrogen were low. Mean contents of pH in the A horizon were 5.15, 4.64 and 5.58 respectively for soils derived from granite gneiss, biotite granite and migmatite. Low pH levels are linked to the basic cations draining out of the profile and the acidic character of the basement complex rocks from which the soils were formed. Soil reaction in most cases indicated that soils had a net negative charge. Available P contents in the magmatic soils was significantly higher than those of other geologic units. Effects of granite gneiss, biotite granite and migmatite parent materials on variation in soil chemical properties were more noticeable for soil reaction and available P contents.

“…A similar report by Abua and Eyo (2013)of the same study revealed a coarse-textured in the surface horizonwith subsurface accumulation of clay and pH (H2O) range of 5.4-6.8, but moderate organic carbon and total nitrogen,low available P and exchangeable bases. But, pH value of 3.8 was obtained by Attoe et al (2016) in the Basement complex soils of Akamkpa with moderate organic carbon and total nitrogen but low available P and exchangeable cations as obtained by Aki et al, (2014), and Abua and Eyo (2013). The soils,so, have high agricultural potentials but may needadequate soil management strategies.…”

Land evaluation, characterization and classification of soil for the proposed oil palm plantation in Ekpri Ibami, Akamkpa Local Government Area, Nigeria was conducted on 50 ha of land using a combination of both conventional and digital survey methods. The objective of the research was to characterize, classify and evaluate the land for the proposed oil palm production. Three soil mapping units were identified (EKP I, EKP II and EKP III) and representative profile pits were dug in each mapping unit. Samples were collected from each pedogenic horizon. Soils morphological, physical and chemical properties were determined using appropriate methods. Results revealed that soils of all of the mapping are characterized by dark greyish brown colour with thin topsoil while yellowish red to strong brown mottles were observed at the subsoil. The soils are coarsed-textured with high sand, low silt, and clay fractions. The soils were strong to moderately acidic (4.8 to 5.3). The soils also have low inherent of natural fertility with low organic carbon content, total nitrogen, and moderately available phosphorus. Low effective cation exchange capacity and high base saturation which may have occurred in available forms in solutions in spite of the low cation reserves in the soil. The individual mapping units were classified as Arenic Eutrudept, Typic Hapludult and Aquic Paleudults for EKP I, EKP II and EKP III respectively. The land was then evaluated and classified based on its suitability for oil palm production. Parametrically, mapping units EKP I and EKP II were marginally suitable and EKP III not suitable for the proposed oil palm production. Non-parametrically, EKPI is moderately suitable, EKP II is marginally suitable and EKP III is not suitable, for growing oil palm. The prevailing limitations on the Ekpri Ibami landscape for oil palm production include fertility, wetness, and topography and soil physical properties. Fertility factor happened to be the most limiting factor in all the mapping units. And thus can be ameliorated through the application of organic manures, NPK fertilizer and liming to improve the nutrient status of the soil.
