BIO Voligop® Zinc

Zinc is an essential micro-element for plants. Upon failure to supplement zinc deficiency, besides damaging the vegetative organs, the development of generative organs is also disturbed via influencing the cell division.

Zinc can be found in the soil in a form that is rather difficult to take up; in the case of overdosage of phosphorus and calcium, the availability is deteriorated. Zinc deficiency may develop in sandy, alkaline, cold, droughty or too wet soils. Zinc deficiency is mostly expected in calcareous soils arising due to the overdosed phosphorus-generated controversial impact.

Zinc deficiency is the most wide-spread micro-element deficiency which may cause up to 20% loss in crop, before the detection of any signs of the deficiency.

Maize, flax, bean, sugar beet, potato, tomato and alfalfa react by significant or medium crop losses to zinc deficiency. By the application of zinc in the case of rape, significant root mass increase can be achieved; roots penetrate to deeper soil layers, thus rape is able to survive drier periods. Its application is recommended for bulb vegetables, poppy-seed, vegetables, furthermore for the sprout enhancement of ornamental trees and evergreens. In the case of soils with excess manganese content, but with a good general supply, the uptake of zinc is limited; therefore in this case foliar application of zinc is especially justified. The product also contains sulphur.

Zinc acts as growth regulator for orchards (stone fruits, /not recommended for plum/, apple, tree nuts, berries). Deficiency of zinc results in branch decline, poor blossom and poor crop production. Zinc (together with boron) plays a crucial role in the seed production of table grapes and wine grapes, and as a result of zinc supply, photosynthesis becomes more effective and the yield increases.
