: difference in nitrogen recommendation based on change in NDVI value. * recommendations determined for wheat at normal planting time sensed at the 1st week of March. rich strip and farmer values are a range of what would normally be encountered in the field. ** recommendations determined for corn with a normal planting date sensed during the 2nd week of June. rich strip and farmer values show both representative and extreme values found in the field. |
