The amount of fertilizer doses should be determined on the basis of soil fertility (soil analysis) and plant demand (unit intake x assumed crop yield per ha). In spring crops, apply half of the planned dose of fertilizer in autumn. If needed, supplement the dose of potassium with e.g. potassium salt. Use in grassland in early spring and / or autumn. The fertilizer is intended only for professional users.
