The following liquid fertilizer and soil amendment programs are very successful programs that golf courses use to maintain their courses. We do have granular fertilizers available. Ask about pricing for your area.
  • A basic lawn program should include either 16-4-8 or 10-8-8 or 12-0-12 NPK along with a monthly use of Soil Amend or Soil Amend Plus and GSR MicroBurst Calcium or GSR Turf Rite Calcium. This can be supplemented with ECO MicroBoost or Dark Green for more green color and to add micronutrients to the soil. Bio-Degrader should be used when there is excessive thatch. Super Soil Plus can be used if the lawn is compacted
