Salmag® as an universal nitrogen fertilizer can be used in presowing and top dressing treatment for all arable crops: winter and spring crops, industrial crops, root and fodder crops, on grasslands and in vegetable and fruit growing from spring to summertime. Due to the content of calcium and magnesium it is recommendable to mix the fertilizer with soil. In top dressing, when there is no possibility of mixing it with soil, the fertilizer should be applied on moist soil and/or before the expected rainfall.
