ACalcium Plus (8-0-0) is a chloride free, economical source of calcium and nitrate nitrogen readily available for plant utilization. Calcium is critical to the function and integrity of cell walls and cell membranes. It is commonly associated with stress resistance. Deficiency symptoms include reddish-brown discoloration in young leaves, reduced, deformed growth in new leaves followed by necrosis. This unique source of water soluble calcium eliminates time and labor necessary to dissolve dry sources of calcium into solution. Calcium Plus is an excellent product to correct calcium deficiencies in ornamental plants, turfgrasses, trees and vegetable crops. Calcium Plus may be used as a foliar spray, in fertigation systems, applied directly as a topdressing, or injected into the soil. It is an excellent source of calcium and nitrogen when blended in clear liquid and suspension fertilizers which do not contain phosphorus.

Application Instructions:
Apply 6 oz. per 1000 sq. ft. of turf in 2.5 gal. of water, or 2 gal. per acre diluted in 50 gal. water. 6 oz. per 1000 sq. ft. supplies 0.04 lb. N and 0.05 lb. Ca per 1000 sq. ft. This product should be used as a supplement to a regular fertility program. It will not by itself provide all the nutrients normally required by plants.
A pre-mix “Jar Test” is recommended to check compatibility of product combinations that have not been previously tested.
Shake well before using.
