The vertical mobility of nitrogen with poultry and sheep manures amendment on degraded Ultisols in Owerri, Southeastern Nigeria

HABEEBAH SAKA*, Bethel Ugochukwu Uzoho, Solomon Oladimeji Olagunju, Musiliat Mopelola Onaolapo

A randomized complete block design experiment was conducted for two years, two locations per year and three months per location with three replications. The rates of dried, milled pure poultry and sheep manures incorporated per location at the onset of the research were 0, 30 and 60 % N. Initial soils and manures were analyzed for macro nutrients. ...

Magnesium Forms in Bulk and Grain Size Fractions of Soils of Contrasting Land - Uses in Imo State, Southeastern Nigeria

Bethel Ugochukwu Uzoho*, Irokwe I. F., Okoli N. H

Magnesium contents in bulk and grain size soil fractions from 2 soil depths (0-20 and 20-40 cm) of 5 land uses (Yam, fluted pumpkin, cassava, pineapple and plantain) in three locations (Amuzari, Umuaka and Ngor-Okpala) in Imo state were evaluated. Total, mineral/structural, acid extractible/non-exchangeable, exchangeable, water-soluble and availabl...

Micronutrient Status of Grain Size Fractions in Soils of Land Uses in Mbano, Southeastern, Nigeria

Bethel Ugochukwu Uzoho*, Irokwe I. F.

Micronutrient status in grain size fractions provides information on the active soil fraction and the ability for stabilization against microbial decomposition. Total, available, exchangeable and water-soluble Fe, Zn, Cu and Mn in bulk and grain size soil fractions were evaluated in three land use types (Cassava, Cashew and Oil palm) in Ehime Mbano...

Status of Available Micronutrients in Soil Profiles of Different Parent Materials in Imo State, Southeastern, Nigeria

Okoli N. H*, Bethel Ugochukwu Uzoho, Onweremadu E. U, AHUKAEMERE C.M., Osisi A. F, Aliba E.O.

The status of available Zn, Cu, Ni and Fe was studied in four representative soil profiles of different parent materials (Coastal Plain Sands, Alluvium, Falsebedded Sandstones and Imo Clay Shale) in Imo State, Southeastern Nigeria. Sample collection was guided by horizon differentiation. Available Zn, Cu, Ni and Fe were evaluated using double acid ...

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...
