Super fos dar 40® is typically a pre-sowing fertilizer. Applicable to plants with a long growing season. It can also be used in autumn and spring, it is best to mix it as deeply as possible with the soil. It achieves the greatest efficiency in fertilizing acid soils and perennials. It is recommended for fertilizing green areas where phosphorus can be easily absorbed by plants. In green areas, this fertilizer can be applied in early spring or summer after the first mowing (in the meadows) or the first grazing (in the pastures). The fertilizer can be used on all soil types, regardless of their degree of soil binding, especially on suitably moist and acidic soils. Super fos dar 40® can be mixed with ammonium nitrate and urea before spreading if these fertilizers are dry, or with potassium salt and potassium sulphate at any time.
