Assessment of Nickel Status Based on Land Use in Selected Soil of Southwest, Nigeria

Thomas, E.Y^*, Omueti, J.A.I, Akpan, I.O

Contrary to the increased alarm that nickel is a soil pollutant, nickel is an essential micronutrient for the growth and development of legume and cereal crops. This study was carried out to assess the status of nickel (Ni) in four different soils under cultivated, fallowed, forest and dumpsite land use and determine the best extractant to be used for Nickel extraction from soil solution. Twenty-f...

Characterization of Biochar Produced from Diverse Feedstocks Used as Amendment on Acidic Ultisols at Umudike, Abia State.

Onwuka, M.I.^*, Nwangwu B.C

Biochar is used as a soil amendment to improve soil nutrients for crop production. The nutrient contents of biochar depend on the type of feedstock, pyrolysis types and temperature among others. In this study, it was hypothesized that biochar produced from different feedstock at the same temperature will have different effects on soil properties. To verify this, a pot experiement was set up at the...
