Salmag® with boron as an universal nitrogen fertilizer can be used from spring to summertime, it is recommendable to apply it mainly for rape, corn and beetroots, both in growing on manure as well as without it. It is also recommendable for other root crops (potato, fodder carrot), fabaceae plants, in vegetables (e.g. onion, leek, brassicas, root vegetables) and fruit growing. For cereals and grass in field cultivation as well as on grasslands it should be used in limited doses to avoid exceeding a 0.5 kg boron dose (up to 250 kg/ha of fertilizer mass).
Addition of calcium and magnesium makes it recommendable to mix the fertilizer with soil (after sowing it). 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.
