İGSAŞ Mn-Zn, which contains 2% water-soluble manganese (Mn) sourced from manganese sulfate and 10% water-soluble zinc (Zn) sourced from zinc sulfate, is a liquid product that can be applied to the soil in the early stages of plant development with drip and sprinkler irrigation and to the leaves at the beginning of the season with a sprayer. It is a manganese-zinc fertilizer. It is an ideal fertilizer solution that can be used from soil and foliage to feed all kinds of plants for manganese and zinc, which are common deficiencies in soils with too much lime, high pH and poor organic matter. Since manganese increases enzyme activities in plant physiology and zinc causes the production of growth hormones and some amino acids, in the absence of both, the development of the vegetative and generative parts of the plant is severely retarded, and product yield and quality decrease. For the solution of all such problems and superior efficiency and quality, İGSAŞ Mn-Zn not only treats plants but also makes humans and cultured animals that consume those herbal products healthy. İGSAŞ Mn-Zn is put on the market in plastic drums and bottles of various sizes.
