  • To guarantee that nitrogen levels in the crop do not exceed a certain limit. (wikipedia.org)
  • Therefore reducing nitrogen levels without affecting overall yield , as achieved by the Koppert Natugro products ProFortum and ProTerrum, is beneficial on several levels. (hortidaily.com)
  • It therefore looks fair to assume we can reduce the nitrogen levels even further, something we will look at in the near future. (hortidaily.com)
  • In this region, sunflower is mostly cultivated before soft winter wheat, which is very often deficient in nitrogen because of a lack of nitrogen in the soil when the wheat needs it. (orgprints.org)
