What can TrueCal do for my crops?

true cal analysis block 300As calcium plays a critical role in the development of all plants TrueCal can promote strong stand and is pivotal in the determination of crop yield. In combination with other essential nutrients, the presence of calcium can help maintain a chemical balance in the soil, reduce soil salinity, and improve water penetration. It can also play a critical metabolic role in the removal of carbohydrates as well as the neutralization of cell acids. It is often applied as an amendment to the soil to promote the health of microbial life and decomposition of crop residues. Calcium is an important constituent in all cell membranes.


As a foundational element to all biological life, calcium is also nature's detoxifier. It is often the most neglected nutrient in many fertilizer programs and it is this neglect that is the primary cause of soil quality decline. 


what's in TrueCal?

TrueCal™ carries a 10 percent guaranteed analysis of soluble calcium that is derived from a non-synthetic calcium chloride brine.  Chloride is necessary for a crop to complete its lifecycle and serves a number of critical functions.

how should I use TrueCal?

Depending on soil analysis, multiple applications of calcium may be more effective than a single application for foliar use. We highly recommend a soil analysis to determine specific application rates. The products we offer are designed to be used together as part of a full-year nutritional program.
