Responses of Maize Growth and Grain Yield to Different Sources and Time of Application of Nitrogen Fertilizer

Omisore J. K.*, Y. A. Abayomi

Soil fertility decline has been identified as one of the major biophysical constraints affecting agriculture in the sub Saharan Africa, including Nigeria. Even though, the use of chemical fertilizer is the most convenient way of improving soil fertility, the high cost and poor distribution of chemical fertilizer have made the commodity inaccessible to resource poor farmers. Consequently, there is ...

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

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 the quantity of soil humic fractions at Umudike, ...
