OMRI Listed Liquid Calcium Supplement for Cell Wall Formation and Fruit Quality (1gal)

Down to Earth Liquid Calcium 5% is an OMRI Listed liquid calcium supplement providing calcium, an essential nutrient that plays many important roles in plant growth. Calcium is needed for cell wall formation, normal cell division in new growth, and proper fruit development. Calcium deficiency can result in poor root development, yellowing of new plant tissue, and fruit and vegetable abnormalities such as blossom end rot in tomatoes. Foliar additions of calcium can be used to correct or prevent deficiencies of this important nutrient.

The 1gal size (Case of 4) makes up to 128 gallons diluted. Suited for market growers and larger operations who apply liquid calcium regularly as a foliar or soil supplement throughout the season.

Who Should Use Down to Earth Liquid Calcium 5%

Liquid Calcium 5% suits organic growers, market farmers, and home gardeners who want to supplement calcium via foliar spray or soil application. It is particularly valuable for tomato growers who want to prevent or correct blossom end rot, and for any grower producing fruiting vegetables or high-calcium-demand crops where deficiency signs appear in new growth or fruit quality.

Calcium and Common Deficiency Symptoms

Calcium deficiency in plants often appears first in rapidly growing tissues — new leaves may yellow or show tip burn, and developing fruit may exhibit physiological disorders. One of the most common calcium-related disorders in vegetable production is blossom end rot in tomatoes, peppers, and squash, which appears as a dark, sunken area at the blossom end of developing fruit. While this disorder can have multiple causes, inadequate calcium availability is a key factor. Foliar calcium applications with Liquid Calcium 5% can help correct or prevent these deficiency-related problems.

Frequently Asked Questions

What causes blossom end rot in tomatoes?

Blossom end rot is associated with inadequate calcium availability in developing fruit tissue. It can result from calcium deficiency, inconsistent watering that limits calcium uptake, or excessive nitrogen that limits calcium movement within the plant. Foliar calcium applications can help address calcium availability.

Is Down to Earth Liquid Calcium 5% OMRI Listed?

Yes. It is OMRI Listed and appropriate for certified organic production.

Can Liquid Calcium 5% be applied as a foliar spray?

Yes. Foliar additions of calcium can be used to correct or prevent deficiencies. Apply as a diluted foliar spray following current label directions for dilution rates and application timing.

What plants benefit most from Liquid Calcium 5%?

Any plant that shows calcium deficiency symptoms can benefit, but it is particularly valuable for fruiting vegetables such as tomatoes, peppers, and squash where calcium deficiency can cause blossom end rot and fruit quality problems.

Can Liquid Calcium 5% be applied through irrigation?

Yes. It can be applied as a soil drench or through irrigation in addition to foliar spray. Follow current label directions for dilution rates by application method.
