Osflo Fertiliser

Osflo Fertiliser is one of the most cost effective Fertilisers on the market. Its unique blend of essential elements and nutrients, combined with chicken manure is proven to stimulate vigorous plant growth.

Osflo Fertiliser has many benefits

  • Naturally Balanced fertiliser
    Osflo contains a rich balanced supply of all essential elements to promote and sustain healthy plant growth and profits
  • Sustainable and environmentally friendly fertiliser
    Osflo contains high organic matter which improves the soil physically, chemically and biologically. It is a sustainable and environmentally friendly alternative to traditional fertilisers, yet it achieves the best results! 
  • Fast acting and sustaining
    Part of the Nitrogen content in Osflo is available immediately therefore it is a fast active fertiliser. The remaining nitrogen is released slowly giving sustained nitrogen activity which is beneficial to the plant and the environment. Extensive trials have proven that this will occur
  • Improves soil pH
    As a balanced fertiliser, regular applications of Osflo will increase soil pH
  • Increases Earthworm activity
    Regular use of Osflo provides an excellent environment for casting earthworms. Earthworms are important for returning leached elements and nutrients back to the plant root zone. Earthworms also increase soil aeration which helps plants establish a deeper rooting system
  • Encourages soil micro-organisms
    Osflo encourages desirable soil micro-organisms and the turnover of soil nitrogen and other nutrients is often stimulated through this increased biological activity
  • Fertmark registered fertiliser
    The Fertmark Programme was established to give consumers confidence in the Quality of Fertilisers. Customers can be confident that Fertilisers supplied from Fertmark Registered Companies are reliable and if used correctly does not pose hazards to food safety or animal welfare
