1 Solub Ammonium Stabilized Water Soluble Fertilizer Nitrogen efficient fertilization for modern irrigation systems

2 Ammonium dynamic Volatilizing How does it work? O2 O2 Nitrosomonas DMPP action Nitrobacter Ammonium-based fertilization with nitrification inhibitor delays the nitrification of Ammonium (NH + 4 ) to Nitrate (NO - 3 ) leads to a more efficient NH + 4 -based N-nutrition Lixiviation Ammonium Nutrition Energy savings by Ammonium-N-nutrition (no biological reduction required) Enhanced flowering (Ammonium promotes synthesis of phytohormones and polyamines) Ammonium nutrition favours root growth PROTEINS PROTEINS ENERGY 20 ATP AMINOACIDS AMMONIUM AMINOACIDS AMMONIUM ENERGY 5 ATP NITRATE Traditional Fertilizer Solub ATP = Adenosine Triphosphate. ATP is one of the most important energy transmitters in organisms.

3 The ph-effect Ammonium nutrition leads to acidification of the rhizosphere Absorption of micro elements and Phosphate is increased by this effect Prevailing NO3-absorption leads to alkalinization (standard fertilizer) fertigation NO3- NH4+ Photo: Römheld, University of Hohenheim Less N-leaching strongly reduces Nitrate leaching due to a higher Ammonium concentration in the soil leads to significant ground water protection N-Urea N-Ammonium Clay-Humus complex N-Nitrate
