eco certified mineral fertilizer with phosphorus, potassium and soluble sulphur

    P2O5 – 13%, K2O – 15%, MgO – 2%, SO3 – 13% CaO - 30%

    Physio-Natur PKS 41 is a complex mineral fertilizer with emphasised content of phosphorus and potassium combined with soluble sulphur which helps the absorption and conversion of nitrogen within the plant.

    Physio-Natur has ECO CERT and as such is applicable in organic production.

    • We recommend the usage of 200 - 400 kg / ha in arable crops, 400 - 1,000 kg / ha in sugar beet and vegetables, and 400 - 800 kg / ha in orchards and vineyards.

    • Application by spreading over the entire surface before plowing or during pre-sowing soil preparation, in vegetable production it is applied in pre-sowing soil preparation or before planting.

    • In orchards and vineyards, it is applied from autumn until the start of vegetation, in the root zone using a fertilizer applicator or on the surface. We recommend the application into the soil.

    • For more details and fertilization plans please contact our sales representatives.

    Expectations & Benefits

    • Phosphorus
      • Improves photosynthesis and respiration of plants
      • Affects plant reproduction
      • Improves rooting, root and shoot formation
      • It directly affects the yield
      • Provides energy in the form of ATP, for plant processes
      • Improves resistance to plant diseases
    • Potassium
      • Essential for plant growth, vitality and quality
      • Allows the transport of nutrients to storage organs
      • Improves nitrogen intake
      • Increases resistance to low temperatures and reduces the impact of drought on the plant
    • Magnesium
      • Improves photosynthesis and facilitates the conversion of nitrogen into nitrate form
      • Improves the absorption of phosphorus in the plant by increasing the energy in the plant
      • Helps build chlorophyll
    • Sulphur
      • Extremely important for proper stem elongation and nitrogen efficiency
      • Increases protein and dry matter content
      • Increases crop yields
      • Helps create amino acids (cysteine and methionine)
    • Marine calcium
      • Greater calcium absorption required for root and root hair development
      • Better activity of microorganisms in the soil
      • Improves bacterial environment, e.g. micro-pH for bacterial activity
      • Better storage of nutrients, e.g., P, K within the clay-humic complex
      • Protects phosphorus from blockade and allows greater availability and efficiency
    • Trace elements (Zn, B)
      • Stimulate plant growth
      • Have a positive effect on the synthesis of sugars and their transport in the plant
      • Improve flowering and fertilization, help the firmness and stability of the stem
      • Increase resistance to frost and low temperatures
