Cal Armor 0-0-3
Cal Armor is a liquid fertilizer enhancer derived from calcium compatible humic acid. Cal Armor contains 3.3% Humic Acid and 3% K2O by weight.
Calcium fertilizers are generally inefficient at supplying calcium to crops. Calcium rapidly binds to open exchange sites on soil particles. Calcium also has an affinity for binding to phosphate in the soil, becoming insoluble. Maintaining calcium availability in the soil is essential to supplying soluble calcium to crops.
Humic acids are widely used for their ability to protect fertilizer ions from soil tie-up and to improve soil chemistry. As a general rule, humic acids cannot be applied with calcium.
pH Range: 5.8-6

Cal Armor is calcium compatible humic acid
Cal Armor protects the calcium in your fertilizer solution and enhances plant uptake of both calcium and nitrogen.
It has been shown to increase soil exchangeable calcium throughout the active root zone. Exchangeable calcium in the soil solution is the calcium that is available for plant uptake. It has also been shown to increase leaf tissue calcium and total N.
Don’t let your calcium fertilizer go out unprotected!
