About Solu-Cal | Enhanced Calcitic Lime

Turf managers know the critical role that soil pH plays in soil health and turf quality. Optimal soil pH is a major factor in nutrient availability, microbial activity, soil structure and overall turf vigor. Maintaining the correct soil pH allows for the most efficient use of applied and soil stored nutrients.

Solu-Cal enhanced calcium and sulfur products allow turf managers to quickly and efficiently address soil chemistry problems. Solu-Cal Enhanced Calcium quickly raises soil pH at ¼ the application rate of traditional liming material. Many products are available in both our micro / greens grades and standard coarse grades. For liquid applications in either spray programs or hydro seeding, Solu-Cal L provides available calcium in a clear no grit liquid. All Solu-Cal products are Powered by Intensify Microbial Biocatalyst, a robust package of nine species of beneficial bacteria & fungi, to help increase nutrient uptake and efficiency.

Maintaining healthy soil requires available calcium and pH management. Partner with Solu-Cal to efficiently manage your soil and your turf.

Did You Know

Solu-Cal, a calcitic lime, is four times more effective than regular lime. If a superintendent is told to use a ton of lime per acre, he can do the same thing with 500 pounds of Solu-Cal. There are labor savings, storage savings, fewer empty bags to fool with, fewer refills.

Why Calcium?

The Forgotten Nutrient

Calcium in the Soil:

  • Primary nutrient in maintaining proper soil pH
  • Improves soil texture
  • Reduces soil compaction
  • Creates better environment for the proliferation of beneficial bacteria
  • Possible links to weed suppression

Calcium in the Plant:

  • Vital constituent of cell walls within the plant
  • Strong cell walls significantly reduce disease and insect pressures and outbreaks
  • Enhances cell tissue strength for greater resistance to heat and traffic stress
  • Increases the availability of N-P-K and other vital micro nutrients
  • Used more by weight and volume than any other nutrient

Why Sulfur?

  • Sulfur is needed by plants in relatively large amounts
  • Aids in the formulation of chlorophyll
  • Aids in the fixation of nitrogen by micro organisms
  • Sulfur is vital in plant metabolism
