Fritzmeier Isaria Pro Compact: Mirrors without smoke
Like most farmers, Dirk Westrup needs to trim costs while still maximizing cereal yield. Knowing that he would need to respect new local rules on maximum fertiliser rate, he looked for a more flexible way to match nitrogen application to plant growth than his old Yara N-sensor.
