N2  - Using the Diagnostic and Recommendation Integrated System (DRIS), complex nutrient ratios were computed for six communal areas. DRIS indices for these areas indicated widespread micronutrient deficiencies in the maize-based cropping system. Regular micronutrient applications are necessary where maize yields as high as 5 t/ha are targeted
