Root feeding with liquid nitrogen fertilizers.
Application of liquid fertilizers in the root zone of the row usually takes place at high air and soil temperatures. This increases unproductive nitrogen losses through denitrification. Therefore, for prolonged nitrogen nutrition it is necessary to reduce the rate at which the ammonium form of nitrogen is converted to nitrate. This can be done by adding the nitrification inhibitor POLYACTIVE N-Boost at a rate of 0.5% to nitrogen fertilizers, namely UAN.
POLYACTIVE N–Boost contains special polymer forms of organic substances that attach to nitrogen ions in the fertilizer, forming a shell that protects nitrogen from volatilization or denitrification. N–Boost protects nitrogen at the molecular level, reducing the availability of the micronutrients nickel, copper and iron to soil bacteria. The protection period can last up to 10 weeks.The effectiveness of N–Boost depends on soil temperature and moisture, which affect how long nitrogen stays protected and available to plants.
Main functions:
- Keeps nitrogen in ammonium form
- Reduces unproductive nitrogen losses
- Improves nitrogen uptake by 10–20%
- Helps increase the yield
- Minimizes the possible effect of nitrogen fertilizers on the environment
