Controlled release NPK complex fertilizer with nitrification inhibitor DMPP (3,4-dimethylpyrazolphosphate), partly coated.
2NT: Unique double Nitrogen Technology, partly coated NPK-Fertilizer-25% of total N is coated.
Controlled nutrient releases
The nutrients are released in two steps:
- Starter effect after application under moisture influence.
- In a second step, the nutrients are released out of the coated granules via diffusion influenced by moisture and temperature.
Under normal influence and under temperate conditions, the controlled supply lasts two to three months. The nutrient supply is linked to temperature, i.e. warm (cold) temperature will reduce (increase) the longevity. Drought will also inhibit the nutrient supply. Both effects ensure that nutrient supply is well-adapted to the plant growth factors.
During the active phase of DMPP (4 to 10 weeks, depending on soil temperature 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.
