Science Into Practice - Novel calcium products for apple storage

Calcium levels in apple are known to be associated with fruit storage potential and bitter pit. The potassium to calcium ratio is important for storage - the greater the ratio of potassium to calcium, the less the storability.

Fruit trees prefer taking up potassium to calcium, so in soils where potassium is present at more than required quantities, fruit quality can suffer.

This is also often the case where composted green waste has been applied as mulch because it is rich in potassium.

Foliar calcium sprays are applied to redress the balance. However, new technologies are available in recently introduced calcium formulations that require evaluating.

HDC project TF 200 - entitled Apple: Determining the Effectiveness of Novel Calcium Products to Increase Fruit Calcium, Increasing Storage Potential & Potentially Reducing Bitter-pit - has been implemented to help determine the effectiveness of increasing fruit calcium concentration and the associated cost of these new products.
