Presented below are the quality ratings with regard to soil moisture availability. Erosion rating Moisture rating Erosion Rating MC (%) Rating Slope Slope rating Rating hazard class Low 1 0-5 4 0-5 1 Moderate 2 5-15 3 5-10 2 High 3 15-20 2 10-25 3 Very high 4 >20 1 >25 4 Quality ratings of three land units are tabulated below. Land quality rating Land unit Nutrient availability Trafficability 1 2 1 2 3 1 3 2 2 Additional characteristics of the land units areas follows: Land Permeability Land use M.C. Slope Clay V.

(b) Establish the quality ratings for each land unit based on the indicated attributes (Nutrient, trafficability, etc). (c) Evaluate the suitability of land for tomato and cabbage production specifying the suitability class. In each case, indicate the limitations that affects the suitability. (d) Recommend ways by which the suitability of land unit 1 for potato and cabbage production can be improved showing how the rating would change.
