SORBCA (Calcium & Boro)

Calcium & Boron

Solution of Calcium (Ca) and Boron (B)

Calcium (CaO) water soluble ................ .................... 9% w/w
Boron (B) water soluble ................. ............................. 0.8% w/w

Boron stimulates the elongation of the pollen tube, allowing fertilization, regulates cell proliferation, thus speeding up the reproductive cycle, favors fruit uniformity and increased fruiting.
Calcium helps in the rapid assimilation of free amino acids , humic acids, betaines, carbohydrates, vitamins and many other components, useful for plant metabolism. It has a fundamental role in the neutralization of organic acids. Calcium also participates in metabolism, the regulation of the colloid state in the protoplasm, acting - unlike potassium - in the processes that regulate sweating and water balance, favoring plasma contraction and reducing water absorbency. It is necessary for cell division. It enters as a component of maltase enzyme and is important for the development of meristems. It is required in large quantities by the plant during pollen formation.
SorbCa is an excellent source of calcium and boron, especially where it is necessary to avoid the incorporation of nitrates (free from nitrates and chlorine ). Its application is recommended preventively and therapeutically for calcium deficiencies in leafy vegetables. horticulture, tuberous plants, fruit trees, peppers and other crops such as tobacco, grapevine, sunflower, cotton and corn.
By adding SorbCa we avoid non-parasitic diseases such as, Bitter bitter-pit (apple tree), Dry Top (Tomato, Pepper) blossonen-rot (vegetables of fruit), Peripheral Burn (Lettuce, Cabbage, Onion, Celery) tip-burn (vegetables of leaf and strawberry), Cracking (cherry-tree and plumtree).

Crops Usage Instructions Dosage
Apple tree 3 to 5 applications from early June to harvest 100 -300 ml / 100L
Stone fruit (Peach, Apricot, Cherry, Plum) precautionary tabs after binding and repeat every 15 days 100 -300 ml / 100L
Vegetables (Tomatoes, Potatoes, Strawberries, etc.) 3 to 5 applications from the tying of the wrists or the formation of the tubers and repetition every 15 days 100 -300 ml / 100L
Vine 2 to 3 applications after binding, closing the grape, and polishing 100 -300 ml / 100L
Vegetables Layer application on 7-8 true sheets and repeat before closing lines 100 -300 ml / 100L
Doses refer to 100 liters of water per acre.
In hydrolubrication during the same phases or when the symptoms appear
1 - 2 L / str

If we want to replace 1 kg of calcium nitrate, 200ml of SorBCA should be applied.
It can be combined with trace elements, organic products and amino acids.
It is not combined with humic acids and alkaline pH products.
