Boost yield and quality with N-Tester recommendations
Sustainable
Reduce nitrogen losses and environmental impact while optimising yield. Precise nitrogen rates reduce your risk of lodging and nitrogen leeching into local waterways.
Reliable & trustworthy
N-Tester recommendations are calculated using over 25 years of Yara product development and field trials studying nitrogen use.
Customisable & efficient
Improve nitrogen use and results each season. Plus, take your results further with variable application and other tools in YaraPlus.
Tailor-made nitrogen rates for each field and season
"Monitoring the crops through the season, with the N-Tester, will give accurate recommendations based on what the nitrogen levels are in the crop. With more accurate rates for each field, the use efficiency will increase, meaning you’re getting the most out of the nitrogen that you are applying.”
