ABSTRACT
Soil loss is a growing
problem worldwide because the fertile top layer of the soil available for food
production is reduced. Most research on soil erosion have focused on the
negative effects of moving agents such as water and wind. However, soil loss
due to harvesting of root/tuber crops like yam and cassava on the farms has
received less attention. This study investigated the amount of soil and
nutrients lost during tuber harvesting and the factors contributing to their
losses based on representative sampling area per location using Oju-Ogun and
Rolu-Osaara as study areas. Soil physical properties: Moisture Content (MC),
Bulk Density (BD), soil particle distribution, soil loss due to crop harvesting
(SLCHcrop) and Soil loss specific (SLCHspec); Soil macro nutrient status:
Nitrogen (N), Phosphorus (P), Potassium (K) and Organic Carbon (OC) and
Agronomic characteristics: Gross Weight (GW), Net Weight (NW), Average Crop Yield
(ACY), and Mass of Crop Yield (MCY) were investigated. Data obtained were
analyzed using descriptive statistics, t-test and correlation analysis. Average
GW, NW, ACY, MCY, MC, BD, Soil and Micro nutrients lost for cassava fields in
Oju-Ogun and Rolu-Osaara were 26.96kg, 25.20kg, 0.61kg, 13684.73kg/ha/har,
10.40%, 1.28g/cm3, 885.19kg/ha/har, (12.09 N, 0.058 P, 0.65 K, 23.22
OC) kg/ha/har and 25.55kg, 24.45kg, 0.60kg, 13546.50kg/ha/har, 6.40%, 1.41g/cm3,
576.99kg/ha/har, (22.67 N, 0.077 P, 0.42 K, 14.12 OC)kg/ha/har respectively.
Agronomic characteristics, moisture content, and bulk density did not
significantly affect SLCHcrop on the cassava fields (P
