Crop and management factor value is significantly corelated with outputs of ANSWERS model especially on soil erosion. Using daily crop and management factors (daily C factors), the ANSWERS model performs well in predicting soil erosion which is showed by determination coeffient (R2 0.89), model efficiency (0.86), and average of percentage model deviations (24.1 %). Whereas using USLE C factor (2 cropping systems), predicted is much higher than measured soil erosion (over estimate). Output of the model is not statisfY; it is represented by model coefficient (0.40) and average of percentage model deviations (63.6%).
