Nutri-Cal®

Nutri-Cal® is a unique liquid calcium formula trusted by professional growers for decades to grow firmer, better-quality fruits and vegetables that store longer. Calcium is one of the most important and often overlooked nutrients in fruit production — it directly affects cell wall strength, which determines fruit firmness, storage life, and disease resistance. Easy to apply as a foliar spray or soil drench, regular application improves fruit quality and promotes disease resistance across a wide range of crops. Non-toxic.

Calcium and Fruit Quality — Why It Matters

Calcium builds strong cell walls, and strong cell walls are what make fruit firm, storable, and disease-resistant. Calcium-deficient fruit is softer, breaks down faster in storage, and is more susceptible to quality-reducing disorders that show up at harvest and during storage. Regular Nutri-Cal® applications supplement available soil calcium with a readily absorbable liquid formula that gets calcium to the fruit efficiently — either through the leaves as a foliar spray or directly through the root system when applied at watering.

Especially Helpful for Honeycrisp Apples — Preventing Bitter Pit

Calcium deficiency is the primary cause of bitter pit — the small, sunken, bitter spots that develop in Honeycrisp apple flesh and represent one of the most common and frustrating quality problems Honeycrisp growers face. Honeycrisp is notoriously calcium-hungry, and regular foliar calcium applications during fruit development are the most effective management tool available. Nutri-Cal® provides that targeted calcium supplementation in an easy-to-apply liquid form that professional Honeycrisp growers rely on.

Two Application Methods — Foliar or Root Zone

Nutri-Cal® gives you flexibility in how you apply it. As a foliar spray, calcium is absorbed directly through the leaves and moves quickly to developing fruit during the critical sizing period. As a root-zone drench applied at watering, it builds soil calcium availability over time. Both methods are effective, and combining them during peak fruit development provides the most comprehensive calcium support.
