Harvest the Value

Calcium and Sulfur are critical nutrients for healthy plant growth. In fact, calcium is a major component of cell walls and often associated with higher fruit quality. The combination of calcium and Sulfur in a readily available form provide the structural building blocks that are necessary for ensuring a healthy crop.

CaTs is a 100% soluble form of calcium and Sulfur that is able to both quickly and efficiently displace salts from the root zone, improve water filtration and help to reduce ammonia loss from urea. The American Association of American Plant Food Control Officials (AAPFCO) recognizes CaTs as a “nitrogen stabilizer” due to its ability to reduce nitrogen volatilization.

Use CaTs to optimize what water you have and make your water work as hard as you do.

Prevent Nitrogen Loss

In addition to its sulfur and nitrogen benefits, adding CaTs to urea ammonium nitrate (UAN) solution is a cost-efficient and highly effective way of reducing nitrogen loss. CaTs has nitrification inhibition properties that slow the conversion of ammonium to nitrate, in turn reducing the chances of nitrogen leaching and denitrification. CaTs can also improve soil structure in high pH soils, enhance water infiltration, assist in breaking down previous crop residues, and enhance nitrogen uptake for the crop.
