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

Onwuka, M. I*, 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...
