Quantification of Soil and Nutrient Loss Due to Yam Harvesting: a Case Study in Two Local Government Areas in Benue State, Nigeria

Victor Manna Samson*, Kumawuese Mercy Ityavnongo

Soil loss due to crop harvesting is a recognized erosion process which has significantly contributed to soil degradation. Despite its significance, soil loss due to crop harvesting has been given little attention in Benue state and Nigeria at large. This is evident in the paucity of information on soil loss due to crop harvesting in Nigeria. Therefore a field experiment was conducted to quantify s...

The Impact of Land Use Types and Acidity Indices on Soil Humic Fractions Quantities at Umudike, Tropical Rainforest, Nigeria

Mabel Ifeoma Onwuka*, Okonta, U, Asobia, P. C.

Natural humic fractions deposited in the soil are most times sources of industrial humic substances use for crop production. However, the quantities of the humic substances, which are components of soil organic matter, are affected by lots of factors and processes, including land- use. The effects of different land- use and soil acidi0ty indices on the quantity of soil humic fractions at Umudike, ...

Effects of Climatic Variations on Leaf Litter Production in A. Floribunda Agroforestry System in South - East Nigeria

Keyejo, A.O, Okpara, D.A., Onyeonagu, C.C., Ernest U. Eteng*

Field experiment was conducted between 2016 and 2018 at Forestry Research Institute of Nigeria (FRIN), Humid Forest Research Station, Umuahia, South-east Nigeria, to study litter production and climatic influence in Allanblackia floribun- da (oliv) agroforestry system. The experiment was laid out in a randomized com- plete block design (RCBD) with three replications. Litter trays were used for mon...

Land Suitability Evaluation for Maize Production and Taxonomic Classification of Soils Overlying Undifferentiated Basement Complex in Northeast Nigeria

Kefas, P. K*, Maigida, E, V. I. Ezeaku, Ofem, K.I, Akwoga, J.A, Peter I. Ezeaku

Soil characterization, classification and evaluation provide useful information for the understanding of its different facets, hence their potentials and limitations for crop production. Such information is lacking in the general area of Kona-Jalingo in Taraba State, Nigeria, hence the study to determine the macro-morphological, physical and chemical properties of the soils, classify them up to th...

Comparative Effect of Variable Rates of Pig and Poultry Manure on the Agronomic Performances of Amaranthus Hybridus in Humid Rainforest South Western Nigeria

Sanni K. O., Adesina J. M.,*, Ewulo Babatunde Sunday, OJENIYI STEPHEN OLUSOLA

The health implication of deficiencies of vital nutrients could be supplemented by taking vegetable which are highly nutritious and easily affordable. An experiment was conducted at the Teaching and Research Farm of the Lagos State Polytechnic, Ikorodu, Nigeria, to evaluate the comparative effects of different levels of animal manure on the growth and yield of Amaranthus hybridus. Pig dung (PD) an...

Impact of Mining on Heavy Metal Concentration and Soil Chemical Properties in Soils Sorrounding a Mining Site in Ebonyi State⸴ Nigeria

Akinmutimi A.L.*, OlughuF.N., Nwangwu B.C

Field and laboratory studies were done to evaluate the effect of land use types on selected physical and chemical properties of soils in Umudike, southeastern Nigeria. Five land use types were studied: rubber plantation, oil palm plantation, forest land, cassava farm land and pasture land. Under each land use system, 3 sampling points were located. Around each of the 3 sampling points, soil sample...

Effects of Parent Material and Land Use on the Variability of Available Cu in a Wetland Soil Under Long - Term Farming System

Ernest U. Eteng*

The study was carried out in the dry season to evaluate the variation in available Cu in wetland soil under long-term farming systems. Twenty four surface (0-20 cm) composite soil samples of acidic nature were obtained and analyzed for available Cu in the soils using five extractants (0.01M HCl, Coca-cola, 0.05M EDTA, 0.05M DTPA, and 1N NH4OAc) respectively. Some important soil char-acteristics li...
