Crop Fertilization Based on North Carolina Soil Tests
Part III:  Notes for Specific Crops / Situations

Special Printout Groups

Two plant groups require lime and fertilizer recommendations that are appropriate for application to relatively small areas. These special printout groups are
  • A. Lawns, Gardens and Ornamentals and
  • B. Centipedegrass.

For both of these groups, lime and fertilizer recommendations are expressed in lb/1000 ft², as shown in Table 3.1. The potassium index (K-I) and the phosphorus index (P-I) determine the fertilizer grade recommended. For special printout group A, the amount of fertilizer recommended supplies 1.0 lb of nitrogen per 1000 ft². For special printout group B, the rate is 0.5 lb of nitrogen per 1000 ft². Note 4: Fertilization of Lawns, Gardens and Ornamentals provides additional information regarding supplemental nitrogen rates and time of application.
