| 1 A more specific guideline will be obtained from a complete Cornell Morgan soil test analysis. |
| 2 For sorghum, sudan-sorghum hybrids, and millets, use 2/3 to 3/4 of the nitrogen rate in the table. Nitrogen may be applied preplant or as a postemergence application if planted after June 1. |
| 3The nitrogen guidelines are based on a broad range of soils. A more accurate guideline for a specific soil, see Nitrogen Guidelines for Field Crops in New York nmsp.cals.cornell.edu/guidelines/ nutrientguide.html. |
| 4To avoid salt damage, do not use more than 80–100 lb./A of N + K2O in the fertilizer band at planting. |
| 5 For nitrogen guidelines greater than 50 lb./A, apply a lower rate in the starter fertilizer (such as 10–30 lb. in the band at planting), and sidedress the remaining nitrogen when the corn is 6–15 in. high. |
| 6Use the lower nitrogen rate for soils with a low yield potential. The optimum economic N rate for corn after soybean can be lowered by 20-30 lbs N/acre. This adjustment should be applied only for the first year of corn following soybean |
| 7For a more accurate estimate of the nitrogen contribution from manure (required for New York State CAFO permits), see Nitrogen Guidelines for Field Crops in New York nmsp.cals.cornell.edu/guidelines/nutrientguide.html |
| 8 See Table 2.10.1 for the soil test values within each level. |
| 9VL = very low; L = low; M = medium; H = high; VH = very high |
