Black Magic is a formulation to improve soil conditions for optimal plant growth. Regular applications of Grogreen Gel Black Magic will improve soil aeration, water holding capacity and soil drainage. It is specially recommended for alkaline and saline soils. Calcium displaces sodium given by sodium-saline water in soils improving crop growth environment. 

This calcium nitrate solution 12 (20) contains 11.40% of nitrogen in nitrate form, immediate assimilation, a small percentage of ammoniacal nitrogen, longer-assimilation, and 20.6% of calcium oxide, fully soluble in water. Its application is very suitable to correct any problem related to calcium deficiencies in soils and demanding crops such as vegetables, fruit trees and citrus.

Improves the appearance of fruits and extends their period of storage. Our product application is very beneficial since the use of acidic fertilizers and continuous bulb washing, especially in sandy soils, reduce calcium content.
