  • Abstract:

This study determined the influence of tillage practices on physicochemical properties of soil. Eight tillage methods used
for the experiment were Ploughing + Harrowing, Ploughing + Harrowing + ridging, Manual Ridging, Flat Manual
Clearing, Ploughing + Harrowing + Manual digging + Saw-dust placed at the base, Ploughing + Harrowing + ridging +
Saw-dust placed at the base, Manual Ridging + Saw-dust and Manual Digging + Saw-dust placed. The physicochemical
properties of the soil examined include pH, Phosphorus, Carbon, Nitrogen, Exchange Acidity, Calcium, Magnesium,
Potassium, Sodium, Iron, Copper, Zinc, percentage clay, silt and sand were determined. Three soil samples from three
different points within the treatment were obtained for each of the eight tillage practices using auger. The results revealed
that the highest value of 6.80 of pH, 7.33 m/kg of Phosphorus, 32.76 g/kg of Carbon, 3.36 g/kg of Nitrogen, 1.00 Exchange
Acidity, 3.43 cmol/kg of Calcium, 0.98 cmol/kg of Magnesium, 1.02 cmol/kg of Potassium, 0.40 cmol/kg of Sodium, 543.00
mg/kg of Iron, 13.70 mg/kg of Copper, 0.68 mg/kg of Zinc, 220 g/kg of clay, 234.00 g/kg of silt and 766.00 g/kg of sand
occurred in conventional tillage practice while the highest value of 777.00 mg/kg of Manganese was recorded in zero
tillage system. There were differences also in the soil texture of for all the tillage practices. This study revealed that tillage
practices had significant effect on physicochemical properties of cassava cultivated soil which will be useful in determining
the appropriate tillage practice to be adopted for a particular crop.
