Increasing and maintaining Ca+ availability in periods of stress and low metabolic activity
Decreasing incidence of Ca+ disorders (e.g. Blossom End Rot, Bitter Pit, Tip Burn)
Increasing mobility of Ca+ across epidermal layer and raising cell sap levels
Disease management through cell wall strength
Foliar application without calcium deposits on fruit and flowers
How does Veni Calcium work?
Most calcium fertilizers contain calcium in suspension. These positively charged calcium ions are bound to large, negatively charged counterions (e.g. sulphates, nitrates, phosphates and chloride). These larger molecules will restrict the movement of the Ca+. In Koppert’s Veni Calcium, a solution, the counterions are small due to the production and application process. This means that the calcium is not locked in a large molecule and can be more easily absorbed across the epidermal layer.
As research has progressed, calcium’s role is being increasingly seen as crucial in the regulation of the growth and development of commercial agricultural crops. Growers are looking for innovative methods to ensure reliable calcium levels are maintained, not only to avoid deficiencies, but to promote crop resilience against physiological and pathological disorders, induce stress tolerance, and promote balanced production.

The efficacy of application depends on the type of crop, leaf coverage, and weather conditions. To test the crop reaction (e.g. precipitation), always apply the product on a small area first before the entire crop is treated. Use Veni Calcium especially during periods of high crop growth and stress. The information given is the recommended standard. Tailored advice requires detailed information on local factors, such as the crop itself, climate conditions and the desired response. Consult a Koppert specialist or a recognized distributor of Koppert products for further information.
Compatibility
Maintain the spray/ irrigation solution within pH range 5 - 6.5 to avoid precipitation
Avoiding co-application with foliar fertilisers, especially phosphates and sulphates
Can be co-applied with the Vidi product range
Results
[Translate to United Kingdom:] The graph illustrates the increased absorption of calcium in the young Elaeagnus leaves.
[Translate to United Kingdom:] During a trial, a serious calcium deficiency was created by supplying the roots with only 5% of the normal required amount of calcium. The application of Veni Calcium resulted in a tip burn index that was 15% better compared to the untreated control. This indicates that the crop is able to effectively use the calcium in Veni Calcium and incorporate it into the cells.
