fosfarm® 4-10-15 is a multi-component fertilizer for pre-sowing application (it is recommended to mix it with the soil), more information at www.nawozy.eu.
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). Depending on the needs, the dose of phosphorus should be supplemented, e.g. with Polidap or Superfos dar, the dose of potassium should be supplemented, e.g. with potassium salt. Use in grassland in early spring and / or autumn. The fertilizer is intended only for professional users.
