SERVAL® NK is a biostimulant based on a high content of amino acids and potassium. The nitrogen in SERVAL® NK has an exclusively organic origin and comes from the amino acids present in it, with a total absence of nitric, ammoniacal or ureic nitrogen sources. The amino acids in SERVAL® NK come from biological fermentation of protein-rich substrates, so they are always L-amino acids, which are those that can be used by the plant, as they are biologically active. The potassium contained in SERVAL® NK is of natural origin and easily assimilated by crops.
Its application is designed for all types of fertigation crops, as a nitrogen and potassium fertiliser, as well as to promote protein biosynthesis and sugar transport, favouring crop development. The application can be made at times of vegetative difficulty (cold and impoverished soils), and at stages of necessary nutritional supply, to promote growth and ripening.
