What fertilizer is best for fruit trees that are calcium deficient?

According to the principle of "apply what is lacking" and "replenish what is lacking" for fruit trees, calcium fertilizer should be supplemented to fruit trees in time after they are deficient in calcium.

There are many varieties of calcium fertilizers on the agricultural market. Most of them are compound calcium fertilizers. In terms of dosage form, there are different dosage forms such as granules, powders, and aqueous solutions .

Generally speaking, it is better to choose granular calcium fertilizer when applying calcium fertilizer to the root zone of fruit trees. When applying calcium fertilizer to fruit trees by flushing, it is better to choose crystalline or water-soluble calcium fertilizer.

When spraying calcium fertilizer on the leaves, it is best to choose water-soluble calcium fertilizer with high calcium content . This is because water-soluble high-calcium foliar fertilizer has better absorption and conversion ability through leaves and has significant benefits.

One of the recommended agents: Heyi Calcium Medium Element Water-soluble Fertilizer.

Heyi Calcium medium-element water-soluble foliar fertilizer can be used throughout the entire growth period of fruit trees, and its usage is not limited to foliar spraying, but can also be used for drip irrigation, flushing and root topdressing.

Heyi Calcium Medium Element Water Soluble Fertilizer is a high content chelated calcium concentrated liquid fertilizer. The calcium content is as high as 150g/liter.

Under the penetration of special absorption aids, the calcium absorption and circulation capacity is very strong. After the application of calcium fertilizer, it can quickly meet the calcium needs of fruit trees and alleviate symptoms such as fruit cracking, bitter fruit taste, and slow root development caused by calcium deficiency in fruit trees.

Increase the commodity added value of fruit trees, improve the beauty of fruits, increase the symmetry and hardness of fruits, extend their shelf life and facilitate long-distance transportation.

Currently on the agricultural supplies market, each bottle of Heyi Calcium Medium-Element Water-Soluble Fertilizer has a net content of 1000 ml. If used for drip irrigation (or flushing), 2 to 4 liters are used per mu, with each use interval of 10 to 15 days.

If used for foliar spraying, the dilution concentration should be 800~1200 times, which can be adjusted appropriately according to the degree of calcium deficiency in the fruit trees.

The second recommended medicine: Kaigong high calcium aqueous solution.

Kaigong high calcium aqueous solution is actually a calcium-magnesium soluble fertilizer produced by Kaia SpA in Italy.

Its main function is to treat nutritional disorders such as leaf yellowing, fruit cracking, bitter taste, bitter pimples, and root tip dysplasia that occur when fruit trees lack calcium and magnesium, thereby achieving the goal of supplementing fruit trees with carbon and calcium at the same time.

Calcium and magnesium supplementation can enhance photosynthesis of fruit trees, promote chlorophyll synthesis and metabolism, and delay aging of fruit trees. It can also increase stress resistance, effectively reduce the probability of fruit cracking and bitter pit disease, and improve the hardness, toughness, taste and flavor of fruit trees.

Kaigong high calcium aqueous solution can be used during the flowering period, fruit setting period, fruit swelling period, etc. of fruit trees.

The commonly used concentration is 750~1200 times. The upper limit concentration can be used in hot or dry weather, and the lower limit concentration can be used in cold or rainy days. The concentration can be adjusted according to the weather when using .

The third recommended medicine: Haomeizi amino acid medium-dose calcium aqueous solution.

Haomeizi is produced by the Netherlands-based company Baion International. Anyone who has ever dealt in agricultural materials knows that this is an international professional fertilizer production company.

Haomeizi medium calcium amino acid foliar fertilizer is in the form of water solution. The amino acid content is 100g/liter and the calcium content is 30g/liter.

The content of free amino acids is 10%, the content of total amino acids is 25%, the total nitrogen is 4%, the organic nitrogen is 4%, and the carbon-nitrogen ratio is less than 5.

The biggest attraction of this foliar fertilizer is its high biological activity, unique formula and quick effect after application. The commonly used application concentration is 2%~3%. The interval between applications is 7~10 days/time.

In addition to the several high-calcium foliar fertilizers recommended above, there are also single-dose calcium fertilizers, crystal calcium-magnesium fertilizers that are a mixture of calcium and magnesium, calcium fertilizers based on humic acid, and paste calcium fertilizers on the agricultural supply market.

Regardless of the type of calcium fertilizer, its purpose is to supplement calcium for fruit trees. When using it, you can choose different dosage forms and concentrations according to production needs to supplement calcium for fruit trees in a timely manner.
