Assessing the effectiveness of applying nitrification inhibitor in stockcamps for mitigating nitrogen loss from grazed pastures
AgResearch (Grasslands, Palmerston North) – Frank Li and K Betteridge
Concluded June 2013
Introduction
Application of the nitrification inhibitor DCD is a promising technology for reducing N loss from grazed pastures, but its application over the whole farm may not be economically justified, especially on hills that require aerial application. Critical source areas (CSAs), such as stock camps, represent the areas of highest urinary-N deposition, highest N loss risk, and potential highest efficacy of DCD application in mitigating N loss.
This work was part of a larger Sustainable Farming Fund Project.
