1 COMPO EXPERT EXPERTS FOR GROWTH 2NT Partly Coated rtilizer Unique Double Nitrogen Technology Immediate and longterm effect Environmentally friendly

2 Double Nitrogen technology 2NT inside Unique Nitrogen Technology 15% coated granules with supply of all nutrients over 3 months = + Remainder of Ammonium N stabilized with DMPP How does it work Mn Mn Mn Mn Zn Mo Zn Mo Zn Mo Zn Zn Mo Mo S S Mo Mo Mo Mo Zn Zn Mo S Zn Zn Zn Mn Mn Mn Zn Mn Zn Mn Zn Mn Mn Mn Mn Mn NPKgranules are partly coated with an elastic polymer. After application, water enters through the pores. The nutrients are dissolved in water. The result is a concentrated nutrient solution. A controlled nutrient release over 3 months. Up to 3 months longevity Partly coated rtilizer: Coated NPK plus noncoated NPK Controlled Release Immediate Release

3 The perfect coating Even thickness Ensuring high crop safety through controlled nutrient release High elasticity High safety; mechanical damage is reduced to a minimum Frost resistance High frost resistance of the new coating, even under high temperature fluctuations Coating consists of elastic polymer and is slowly broken down in the soil High elasticity of coating Release linked (CARTechnology) to temperature Ensures nutrient availability according to the plant requirements High application security Trace element supply Micronutrients (,, Zn) are supplied in every granule Photo: Microscopic view (2000x) of a granule
