High bioavailability of manganese and zinc
Fertigation • Foliar
Stemma Mn LS and Stemma Zn LS are liquid products based on manganese and zinc complexed by lignosulfonic acid (LS).
LS is an organic molecule from vegetal origin, which acts as highly effective carrier through the leaf cuticle and through the vegetal tissues for Zinc and Manganese.Thanks to the complexing action of LS, Stemma LS have a quick efficacy also a low rate.
