Calcium deficiency-Apples

Apple: At establishment and for young, non-bearing trees apply .1-.25 pounds N/tree. Utilizing YaraLiva products such as Calcinit 15.5-0-0 (dependent upon application preferences and cultural practices) will supply nitrate N for rapid uptake and vegetative growth. Soluble Ca is also provided which ensures proper cell division and growth during tree establishment. For established orchards, apply 55-70 pounds N/tree is split applications at post harvest and again in spring at flowering. The rate is dependent upon several factors such as soil and tissue analysis as well as variety, tree population and pruning. Calcium is also very important for cell wall strength and to ensure against physiological disorders such as bitter pit. Consult local agronomist for further details and local recommendations.

Apple: For orchard establishment, apply .5-1.5 lb YaraLiva® CAN-17/tree. For established low density orchards, apply up to 6 lbs CAN-17/tree/year in split applications at post-harvest, and in the spring at flowering, according to variety, soil and tissue samples. Utilizing YaraLiva® CAN-17 for part or all of the nitrogen needs supplies the crop with fast acting nitrate nitrogen and since CAN-17 contains 8.8% Calcium it will provide soluble calcium in proper ratio with nitrate nitrogen. Calcium is important for fruit firmness and to prevent disorders such as bitter pit. Consult with your agronomist for local recommendations.

Apple: At establishment and for young, non-bearing trees apply .1-.25 pounds N/tree. Utilizing YaraLiva products such as CN-9 (dependent upon application preferences and cultural practices) will supply nitrate-N for rapid uptake and vegetative growth. Soluble Ca is also provided which ensures proper cell division and growth during tree establishment. For established orchards, apply 55-70 lbs N/ac in split applications at post harvest and again in spring at flowering. The rate is dependent upon several factors such as soil and tissue analysis as well as variety, tree population and pruning. Calcium is also very important for cell wall strength and to ensure against physiological disorders such as bitter pit. Consult local agronomist for further details and local recommendations.

Apple: At establishment and for young, non-bearing trees apply .1-.25 pounds N/tree. Utilizing YaraLiva products such as Tropicote(dependent upon application preferences and cultural practices) will supply nitrate N for rapid uptake and vegetative growth. Soluble Ca is also provided which ensures proper cell division and growth during tree establishment. For established orchards, apply 55-70 pounds N/tree is split applications at post harvest and again in spring at flowering. The rate is dependent upon several factors such as soil and tissue analysis as well as variety, tree population and pruning. Calcium is also very important for cell wall strength and to ensure against physiological disorders such as bitter pit. Consult local agronomist for further details and local recommendations.

Apple: At establishment and for young, non-bearing trees apply .1-.25 pounds N/tree. Utilizing YaraLiva products such as UCAN-17(dependent upon application preferences and cultural practices) will supply nitrate N for rapid uptake and vegetative growth. Soluble Ca is also provided which ensures proper cell division and growth during tree establishment. For established orchards, apply 55-70 pounds N/tree is split applications at post harvest and again in spring at flowering. The rate is dependent upon several factors such as soil and tissue analysis as well as variety, tree population and pruning. Calcium is also very important for cell wall strength and to ensure against physiological disorders such as bitter pit. Consult local agronomist for further details and local recommendations.

Apples: Repeat applications of 1-2 quarts/acre at 7 to 10 day intervals applied from petal fall. A single application of up to 2-4 quarts/acre may be made from petal fall to just after "June drop". Minimum water rate: 20 gallons/acre. Note: Late applications may leave a deposit on the crop. For use in Wisconsin: Caltrac can be applied to this crop in Wisconsin where supplemental calcium has been shown to be of benefit to plant storage organs and where soil test calcium is low. Also on crops where supplemental calcium has been shown to improve the resilience to physiological disorders.

Apple: Several applications of 1 to 2 quarts/acre beginning at pink bud, start of flowering, at petal fall, after fruit set and during sizing. Also, after harvest but before leaf senescence. Water rate: 15 gallons per acre minimum.

Apples: 3 to 8 applications of 1-4 quarts/acre at 10 to 14 day intervals commencing at petal fall. One or two applications (7 days apart) should be applied alone once the fruit has started to change color, normally 2 to 3 weeks before harvest. Water rate: 50 to 100 gallons/acre.

Apple: Regular applications of 2-4 quarts/acre at 7 to14 day intervals from petal fall to one week before harvest. Water rate: 15 to 50 gallons/acre. For use in Wisconsin: This product can be applied to this crop in Wisconsin where supplemental calcium has been shown to be of benefit to plant storage organs and where soil test calcium is low. Also on crops where supplemental calcium has been shown to improve the resistance to disease.

Apple: 5 to 25 lb per acre per application. Repeat as needed. Apply aerial applications in at least 5 gallons/acre and ground applications in at least 10 gallons/acre; however, when total application gallonage is 25 gallons per acre or less, DO NOT mix more than 1 lb. of this product per gallon of water.
