Pedogenic Forms of Iron and Manganese and Its Implication on Soil Genesis Over a Lithosequence in Nigeria

The citrate-bicarbonate-dithionite extractable iron and manganese oxides (Fed and Mnd), oxalate extractable iron and manganese oxides (Feox and Mnox), sodium pyrophosphate extractable iron and...

Digital Mapping of Cultivated Land in Two Peri - Urban Areas of Ibadan, Nigeria

The need to save time, money and enhance quality as well as precise soil survey information through improved methodologies calls for digital soil mapping: hence, this study was conducted to map the...

Characterization, Classification and Agricultural Potentials of Some Coastal Plain Sand Derived Soils in Lagos State

Detailed soil surveys were carried out on a total of 194.5 hectares of the land at Igbokuta and Ibomwon areas in Ikorodu and Epe local government areas of Lagos state. Grid survey method was...

Effect of Particle Size Biochar (rhizophora Racemose) of Red Mangrove on Bacteria Population in Crude Oil - Contaminated Soil.

Soils contaminated at different levels of crude oil were amended with two- particle-sized fractions of red mangrove biochar [ mm (B1) and 4 mm (B2)] from locally pyrolyzed red mangrove in earthen...

Effect of Biochar on Available Phosphorus Status in Alfisols Derived from Charnockite in Ekiti State, Nigeri

Biochar, a carbon-rich product of pyrolyzed biomass, has been used as an amend- ment to improve the properties of marginal highly-weathered soils in the tropics characterized by widespread phosphorus...

Biological Nitrogen Fixation and Productivity of Soybean in Maize - Soybean Intercrop Under Tillage and Bradyrhizobium Inoculation on Alfisols of Northern Guinea Savanna, Nigeria

A field study was conducted in the 2011 cropping season to investigate the effect of tillage and bradyrhizobium inoculation of soybean on biological nitrogen fixa- tion (BNF) and yield components in...

Genotypic Effect of Groundnut on Nodulation, N Fixation and N Balance in the Two Savannahs of Nigeria

Identification of high N-fixing groundnut genotypes and integrating them into the prevailing cereal-based cropping systems can reduce the need for nitrogen (N) fertilizers, thus minimizing their high...

Vegetative Growth and Yield Response of Amaranthus Hybridus to Mycorrhizal Fungi (glomus Mosseae) Inoculation, Organic and Micronutrient Fertilizer Application

This study was carried out at the Faculty of Agriculture Teaching and Research farm, University of Benin during the early planting season in April 2016 to evaluate the growth response of Amaranthus...

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

Soil characterization, classification and evaluation provide useful information for the understanding of its different facets, hence their potentials and limitations for crop production. Such...

Effect of Different Organic Composts and Inorganic Fertilizer on Nodulation, Nitrogen Fixation and Grain Yields of Soybean (glycine Max L.) Under Field Conditions.

The study assessed the effects of composted corn wastes, poultry droppings and inorganic fertilizer on the number of nodules, nitrogen fixation and grain yields of soybean (Glycine max L.) under...
