Ultimately, the challenges posed by the new fertiliser regulations are always about using fewer mineral nitrogen fertilisers - such as KAS, urea, ASS or AHL - to fully exploit the site-specific yield and quality potential. We set ourselves the task of solving precisely this challenge years ago and launched StradiVari®, a highly efficient nitrogen leaf fertiliser. StradiVari® forms a sustainably available nitrogen depot in the plant and thus ensures the nitrogen supply regardless of, for example, drought and lack of mineralisation. In this way, nitrogen efficiency is achieved that is significantly higher than with conventional nitrogen fertilisation via the soil or the leaf.
