SORBCA (Calcium & Boro)

Calcium & Boron

EC Fertilizer
9% CaO & 0.8% B
SorBCA has got a high concentration of Calcium & Boron.
Boron is an essential micronutrient for plant production processes.
It stimulates the lengthening of pollen tube, allowing fecundation, it regulates cell multiplication, thus achieving reproductive cycle and it favors homogeneous and a bund ant fruits.
In this formulation, boron forms a complex with ethanolamine that hasproved to be the most suitable element to ensure the availability of the element in the plant.
If SorBCA is administered to plants, it restores the right balance of this element.
SorBCA is an excellent source of calcium and boron, especially where it is necessary to avoid the incorporation of nitrates. Its application is preventively and therapeutically recommended for calcium deficiencies in leafy vegetables. horticulture, tuberous plants, fruit trees, peppers and other crops such as tobacco, grapevine, sunflower, cotton and corn.
Adding SorBCA avoids non-parasitic diseases such as bitter-pit (apple tree), blossonen-rot (vegetables of fruit), Tip-burn (vegetables of leaf and strawberry), Cracking (Cherries, Plums)
