Calcium Nutrition for Tree Fruit
Applying enough Calcium is key in getting apple bitter-pit programs to work. Honeycrisp apples treated with TECH-GRO MIRA-CAL 30% showed an increase in peel Calcium concentration, leading to a reduction in bitter-pit at harvest AND after 90 days of CA storage.
Getting good results from foliar Calcium starts with the right product. TECH-GRO™ MIRA-CAL is a 100% water-soluble powder designed to be compatible with most crop protection materials including spray oils. Growers like that they can apply MIRA-CAL on cool mornings of days above 100o F.
Calcium is essential during early season cell division and growth, resulting in a distinct effect on vegetation and fruit set. It is important for forming cell walls, rigid structure, enhancing pollen germination and growth. Calcium increases flavor and storage capability; prevents or controls a large number of disorders in plants. Once deposited in plant tissues, it is not easily remobilized. Therefore, young tissue is affected first under conditions of deficiency.
