Serval NK is a physical mixing of amino acids and salts natural potassium. Serval NK, is not a racemic mixture of amino acids from hydrolyses fatty acids. In fact, the amino acids of Serval NK from the fermentation of organic bacteria (Corynebacterium glutamicum) substrates rich plant  proteins, so they are biologically active and also very assimilated by the plant. On the other hand, the nitrogen of Serval NK has an origin exclusively organic from the amino acids present in the product ; 

Sources nitric, ammoniacal and urea are absent. 

Potassium also comes from natural sources, which makes Serval NK fertilizer use on crops growing in accordance with the rules of organic agriculture. In addition to the input of nitrogen and potassium to the plant, Serval NK active synthesis of biological proteins and contributes transport photos-assimilat . Serval NK also has a powerful role to makes bio-stimulating to divert the difficulties vegetative related to periods stress climatic and physiological..

Dose and mode of employment

The doses depend on the culture, the time of year and the nutritional status of crops.

Spray : 250 to 500 g /Hl (2.5 to 5 Kg /Ha).

In fertigation : 3 to 5 Kg /Ha.

Compatibility

Compatible with most pesticides and fertilizer, the effectiveness of these even increased due to the presence of amino acids. It is advisable to conduct a compatibility test on a small scale  and prior employment.
