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 Effect of Rice Husk Dusts Treated with Urine on Soil Fertility Status and Yield of Upland Rice in Abakaliki, Southeastern, Nigeria

Igboji P O^*, Onyibe, C.E

To enhance nutrient release by rice husk dust, it was treated with human urine, swine slurry and water, with an untreated rice husk dust and control (no rice husk dust) as standards. These treatments were laid out in the field in a Randomized Complete Block Design (RCBD) replicated four times. The result shows that human urine decomposed material recorded pH of 5.89 (medium acid), total organic ca...
