ABSTRACT
A field study was conducted to assess the run-off soil and nutrient losses in different agro – forestry land use systems. The results revealed that among the different land use system the Silvi – horti system recorded highest organic matter loss (45.20 kg/ha) major nutrients loss (30.30 kg/ha) secondary nutrients loss (250 kg/ha) and micro-nutrients loss (9.38 kg/ha). Whereas it was least in natural land use system. Organic matter loss (13.64 kg/ha) major nutrients loss (10 kg/ha) secondary nutrients loss (85.80 kg/ha) and micro-nutrients loss (3.10 kg/ha) with land use system respectively. However the highest soil nutrient losses from Silvi-horti system may be attributed to higher run off soil losses from the system. Where the highest amount of natural resource of soil nutrient losses was recorded in Silvi-horti system (2.30 t/ha) followed by Agri-horti system (2.25 t/ha) Agri-system (2.20 t/ha) Silvi-horti – pasture system (1.20 t/ha) and lowest was natural land use system (0.65 t/ha) respectively.
Key words :
Natural resource management, Nutrient loss, Organic matter, Run off soil, Silvi-horti system, Soil erosion.
