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 where the calcium will displace the sodium and will improve the root growth environment.

This product is a special combination of calcium(-nitrate) with humic acids, sugars and trace elements in a low pH product that is completely water soluble. Its application is very suited to correct any problems related to calcium deficiencies while also improving soil microbiological life and the soil structure which will result in a better plant performance.

Black Magic is also useful as a seed treatment for cereals to increase germination rates.
