Piagran Pro Fertiliser - urea with inhibitor
PIAGRAN® PRO is granulated urea with the urease inhibitor 2-NPT, which reduces the risk of ammonia emissions.
Description
PIAGRAN® PRO is granulated urea with the urease inhibitor 2-NPT – a fertiliser for difficult conditions that reduces the risk of ammonia emissions. The urease inhibitor (2-NPT) slows the conversion of urea to ammonium ion by 1–2 weeks.
The resulting ammonium ion can therefore bind more easily to the soil. The risk of ammonia losses is almost completely eliminated. Piagran® Pro optimises nitrogen efficiency and guarantees high yields of good quality. The high stability of the active substance 2-NPT in the fertiliser granules ensures high effectiveness, even during storage for over 12 months.
Chemical composition:
- urea with urease inhibitor (2-NPT) 46;
- 46% total nitrogen calculated as urea nitrogen.
