Calculate the percentage change in predicted erosion rates if a field that initially has a flat wheat residue cover of 500 kg/ha and a roughness of 30 mm is cultivated to give a cover of 100kg/ha but a ridge roughness of 125 mm using both Equation 2.2.9 and 2.2.10. Comment on the effect of cultivation on erosion.
