Effect of Different pH Levels on Adsorption and Desorption of Pb in Contrasting Parent Materials of South Eastern Agro Climatic Zone of Nigeria

Nkwopara, U. N.*, Onwudike S,U., Ihem, E.E, Osisi A. F, Egboka, N.T

Lead adsorption and desorption at different pH levels in acid soils of diverse par- ent materials were evaluated. The soil samples were collected from soils under- lain by olivine basalt (Ikom), coastal plain sands (Ihiagwa) and false bedded sandstone (Ishiagu). The collected samples were air -dried, crushed, sieved with a 2 mm sieve and analyzed i...

Forms of Primary Nutrient Elements in Soils Overlying Contrasting Parent Materials in South - Eastern Nigeria

Ahukaemere, C.M.*, Bethel Ugochukwu Uzoho, Ndukwu, B., Onwudike S,U., Okoli N.H., Irokwe I. F.

Appropriate management of soil fertility should rely upon sound knowledge of the nutrients reserve and their availability. This is only possible if there is adequate information on the influence of parent material on the dynamics and availability of these nutrient elements. Research was carried out in 2014 at three locations underlain by three diff...
