Over the last few years, tight crop rotation with a high proportion of maize has caused a decrease in humus and therefore made our soils less able to provide a reliable yield. Innovative farmers recognised forage rye as a supplement to biomass crop rotations a few years ago. Forage rye is suitable for use in fodder and biogas. It tillers more strongly and quickly begins to grow vigorously in spring so it can be harvested before the maize. Dense root penetration helps stabilise humus.
