Main advantages
About this product
Granular ammonium sulphate with silicon — a nitrogen-sulphur fertilizer containing 19% nitrogen and 21% sulphur in a granular form that is convenient for application. In addition it contains active silicon and humic compounds, which act as a natural chelating agent, improving soil aeration, moisture retention and resistance to erosion. Polysilicic acids convert micronutrients, in particular iron and zinc, into a form available to plants. It is especially effective on soils poor in humus for field crops, orchards, vegetables and berries in spring and in summer.
