Borealis L.A.T GmbH and its subsidiaries not only just give a contribution to the success of the farmers with the production and sale of high quality fertilizers, but also put a premium on the proper, professional support for the application of the fertilizers. Therefore since several years we make own field trials on a lot of locations. Since 2011 our field trials already take place in four countries, in cooperation with farmers and agricultural universities and research institutes. The aims of the trials are the development of such plant nutrition technologies that are most fitting to the regional circumstances (soil, climate), and to the needs of the given field crop; and to test these technologies in practice. We present our results to our partners on field days, in PR articles and winter presentations. During the field days the farmers have the opportunity the visit the plots and have a look at the plants, so they can personally make sure of the effectiveness of our fertilizers.
