Evaluation of Lower Niger River Floodplain Soils of Bayelsa State, Southern Nigeria for Their Agricultural Capabilities

Achimota A. Dickson*, FunsoR. Kutu, Joseph Aruleba

Capabilities and fertility constraints to crop production of the Lower Niger River floodplain soils were assessed using Land Capability Classification (LCC), Land capability Index (LCI), and the Fertility Capability Classification (FCC) systems. The LCC grouped the nine soil mapping units (SMUs) into class II, suited for a wide range of arable crops while LCI grouped ELM1 into class I, ODN1 and TF...

Effect of Organic Soil Amendments on Soil Chemical Properties in Sudan Savannah of Nigeria

Aliyu Abdulkadir*, Dawaki M. U., Mahmud Sani

Composite soil samples were collected from irrigated maize fields, to study the effect of Bio char and Compost on post harvest soil chemical properties in the Sudan Savannah of Nigeria. Laid on a completely randomized block design, the treatments used in the experiment were 5tha-1 Bio char, Compost, and Control. Pre-amendments application and post maize harvest soil characteristics obtained from l...

Contamination Status and Ecological Risk Assessment of Heavy Metals in Wetland Soil, Federal University of Agriculture Abeokuta Nigeria

olatunde K. A.*, Adekola M. B., Jimmy T. A., Koko O. O., Ekhator F. O., Adekunle A. A.

Wetlands are one of the most productive habitats globally, with socio-cultural and economic relevance. They are, however, at risk of heavy metal contamination. This study investigated metals distribution and potential ecological risk in wetland soils at the Federal University of Agriculture in Abeokuta, Nigeria. Soil samples were collected in March 2021 and analyzed using standard methods. Metal c...

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 in the laboratory. The adsorption of lead (Pb) incr...

Effect of Tillage and Maize - Cowpea Intercrop on Fractal Features of Particle and Aggregate Size Distribution on a Tropical Sandy Loam Soil in Southwest Nigeria

ADESODUN Johnson Kayode*, Udom B. E., Adekunle A. O, Adejuyigbe C. O.,, Atayese M. O., Olowokere F. A., Mbila M., Oyegoke, C.O,

The effects of tillage and cropping pattern on soil aggregation, fractal dimensions and distribution of organic carbon fractions were studied. Treatments were no- tillage (NT), conventional tillage (CT), and four cropping patterns viz: sole maize, sole cowpea, maize-cowpea intercrops and control (no crop). Soil samples were analysed for particle size distribution (PSD), aggregation ratio (AR), mea...

Physicochemical Properties of an Alfisol Under Fallow and Adjacent Forest Lands and Their Suitability for Cocoyam, Pigeon Pea and Sweet Potato Production in Nsukka, Southeastern Nigeria

Ugadu, M.E*, Asadu Charles Livinus

Forest land provides a wide range of ecosystem services such as reducing the impact of raindrops on the soil and maintenance of soil fertility, whereas fallowing is one method used in restoring the fertility status of degraded farmlands. This study evaluated the physicochemical properties of an Alfisol under fallow and adjacent forestland, and their suitability for cocoyam, pigeon pea, and sweet p...

Effect of Solid and Liquid Tea Compost on the Growth , Yield of Amaranthus Cruentus and Soil Properties in Ekpoma, Delta State.

Dania S. O.*, Oshokhayamhe B. I, B. I and Uche, A, L.

Improvement of soil nutrient and organic matter contents is essential to enhance the growth and yield of crops. Two seasons experiments were conducted to evaluate the effect of solid and liquid compost on the growth, yield of Amaranthus and soil properties in Ambrose Alli University Teaching and Research Farm, Ekpoma. The treatments (control, compost tea, solid compost) were laid out in Randomized...
