Description

NovaTec^® Solub is an ammonium-stabilised water soluble fertiliser with the nitrification inhibitor DMPP (3,4-dimethylpyrazol phosphate). DMPP slows down the nitrification process, i.e., the transformation from NH₄ to NO₃ for several weeks. As a result, N availability is further adapted to plants’ requirements, N efficiency is increased and N leaching is reduced.

Benefits for plant growth

• NovaTec^® Solub increases plant availability of phosphate & micro nutrients due to acidification of the rhizosphere by ammonium uptake instead of nitrate uptake.
• Less energy consumption in N-metabolism of the plant, due to partial NH₄- nutrition. Energy usually required for nitrate reduction are used for other processes of plant metabolism.

Effects of DMPP on N₂0 emissions

• NovaTec^® Solub nitrification inhibitor reduces N leaching and increases N efficiency. During the active phase of DMPP (4-10 weeks, depending on soil temperature, soil type and soil humidity), the transformation of ammonium to nitrate is delayed. As a result, N availability is further adapted to the plants’ requirements and N efficiency is increased.

DMPP - mode of action

• NovaTec^® Solub results in a more efficient nitrogen use compared to conventional fertilisers. Nitrogen losses through nitrate leaching are minimised and a better adapted plant supply is achieved. NovaTec^® Solub ammonium is stabilised and the DMPP effects only the Nitrosomonas soil bacteria involved in the first stage of nitrification. Nitrobacter and other micro-organisms are not affected.
