  • granulated fertiliser intended for most types of crops
  • a valuable source of phosphorus in different chemical forms so that the phosphates from the fertiliser are released throughout the growing season
  • the ammoniacal nitrogen contained in the fertiliser granule binds well in the soil and supports the uptake of phosphorus, both from the fertiliser granules and from the soil
  • the added sulphur improves the efficiency of nitrogen fertilisers and also improves the defence of the plant against pathogen attacks
  • can be used in a set of pre-sowing cultivation measures for winter plants (rapeseed and cereals), ensuring an adequate supply of nitrogen, phosphorus and sulphur for the plants in autumn
  • when fertilising spring plants and permanent grasslands, it provides the full dose of phosphorus and increases the amount of available nitrogen in the first vegetation period
  • the fertiliser can be successfully used for precise strip-till fertilisation or localised fertilisation performed together with corn sowing

Granulated fertiliser intended for fertilising crops. Can be used in a set of pre-sowing cultivation measures for winter plants (rapeseed and cereals). The fertiliser should be applied before sowing the plants and mixed with the topsoil after application. On permanent grasslands, it should be used during the beginning of spring vegetation. In conditions of a strong phosphorus deficit, a part of the planned dose (20% to 30%) on the grasslands can be applied in autumn. When used in autumn, it will improve the winter hardiness of the plants. The fertiliser can be recommended for localised corn fertilisation. In this application technique, the recommended dose should be reduced by 30% to 50%, depending on the nutrient content of the soil. The dose of the fertiliser should be determined based on the nutritional demand of the plants, for the expected yield and the nutrient abundance of the soil.
