Variability of Some Properties of the Nun River Plain Soils in Bayelsa State, Nigeria

Achimota A. Dickson*, Tate, J. O, Ogboin, P. T, Payebo, O. C, Agbai, W. P.

Whereas studies on spatial variability of soil properties on toposequences are well documented, information on the variability of characteristics of floodplain soils is lacking. This study, therefore, evaluates the status and variability of the soil properties in three physiographic units in two locations on the Nun River floodplain. Silt-sized particles dominated soil texture and soil texture var...

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

Uzoho B. U*, 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 available Mg were subjected to ANOVA and means separated u...

Fertility Status of Fadama Soils in Asaba, Delta State, Nigeria

Ojobor Smart*, Aimufia, Precious Nosakhare

An experiment investigated the fertility status of fadama soils in the Asaba environment, Delta State. The study area was divided into twelve blocks, and ten representative soil samples were taken from each block to form one composite sample that was air-dried at room temperature and sieved with a 2 mm sieve. Particle size distribution, soil pH, organic carbon, total N, available P, exchangeable b...
