Highly available 10% liquid calcium fertilizer

Calcium plays a critical role in the development of all plants. Calcium promotes a 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 the decomposition of crop residues. Calcium is an important constituent in all cell membranes.

How to Apply

TrueCal™ may be used in both foliar and soil applications. 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.

Do not mix TrueCal™ with materials containing phosphates or sulfates or with any glyphosate-based herbicides. A jar test should be performed to ensure compatibility when mixing with any other material.

Soil Application:
• 2-4L / ac

Foliar Application:
• 2-6L / ac

Nitrogen Applications:
• Add 4-8 L / ac to all nitrogen applications

Dilute TrueCal™ with clean water to create a 10-20% solution and spray onto soil or foliage to improve available calcium.

TrueCal™ can be blended with Humic Acid, SeaPack Liquid Fish and other fertilizers to enhance nutrient availability and uptake

* A jar test should be conducted when mixing TrueCal™ with any other product to ensure compatibility.
