Borocal Plus Calcium & Boron Complex is chelated with carboxylic acids that assist in the absorption of Calcium and Boron in the most rapid and efficient manner. Supplying the fruits with Calcium will promote longer shelf life and will resist physiological breakdown conditions like a bitter pit in apples, tip burn in lettuce & blossom end rot in tomatoes. Pollination is greatly influenced by boron availability. Sufficient boron is required for pollen-producing capacity and pollen grain viability. The combination with boron allows the calcium to be rapidly assimilated and transported to the places to be used. Borocal Plus can be used by foliar application and by fertigation. Contains trace elements chelated with EDTA to ensure optimal plant growth.
