Recommended Rates

Sysstem-Cal is intended for foliar use only. Foliar: Apply 1 to 5 quarts per acre (2.5 to 10 liters per hectare) with sufficient water for thorough coverage. Do not apply during the “sunlight” hours when air temperature is above 85° F/30° C. Foliar fertilization is intended to supplement standard ground fertility programs and will not by itself provide all nutrients normally required by agricultural crops. If you have any questions regarding mixing or application rates contact Agro-K before using this product. Sysstem-Cal is compatible with many fertilizers and pesticides, but compatibility checks are recommended before mix. If mixing Sysstem-Cal with other products, dilute Sysstem-Cal in a full spray tank first before adding other products. Sysstem-Cal should not be mixed with pesticides or other products that are sensitive to low pH solutions.

*Always read and follow the product labels for more complete information and application directions. Check your state product registration status before using any product.
