Preventing Fruit Cracking and Improving BRIX

Preventing Fruit Cracking and Improving BRIX in High-Value Crops

For growers of high-value fruit crops—such as table grapes, citrus, cherries, and berries—harvest quality directly determines market price. Two common challenges during the ripening phase are fruit cracking and low sugar content (BRIX levels). Fruit splitting damages commercial appearance, creates entry points for post-harvest pathogens, and leads to severe financial losses.

Fruit cracking typically occurs during rapid fruit expansion or sudden heavy rain following dry spells. When water influx outpaces peel elasticity, epidermal cells rupture. To prevent this, crops require bioavailable calcium and boron. Calcium strengthens the structural integrity of cell walls, while boron regulates sugar transport and cell division. Traditional synthetic calcium sources often react with sulfates or phosphates in fertigation tanks, becoming insoluble and unavailable.

High-efficiency organic water-soluble formulas solve this through organic chelation. Sugar-alcohol chelated calcium and boron complexes remain fully soluble and mobile within plant phloem, ensuring rapid translocation directly into expanding fruit tissue.

Simultaneously, increasing BRIX levels requires optimized potassium nutrition and metabolic catalysts. Late-stage applications of high-potassium organic water-soluble fertilizers, combined with natural potassium humate and seaweed extracts, accelerate the movement of photosynthetic sugars from leaves into the fruit.

By applying chelated secondary nutrients alongside organic biostimulants during fruit development, growers achieve uniform color, higher BRIX readings, thicker fruit skins, and extended post-harvest shelf life.
