High maize content in crop rotation inevitably leads to a negative humus balance. Cultivation of maize takes up to 600 kg of humus carbon from the soil each year. To compensate for this loss of humus, the correct components have to be selected for crop rotation.
Grasses make a valuable contribution to the formation of humus and counteract humus decomposition.
Wild plants serve as fodder and shelter to many animals. They can also form an ecological priority area.
Wild plant mixtures also offer very attractive views during the growing season, thus helping to improve the image of the biogas industry. In addition to wild plant mixtures, there are also other attractive biogas express mixtures that offer an appealing option for creating a positive humus balance. Examples of this include mixtures BG 30 and BG 50.
for fermenters and soil
Biogas express clover/grass mixtures with short-lived ryegrasses for annual and short-term perennial use.
Grasses from field feed production or permanent grassland are ideal for biogas plant use. They also keep soil in excellent condition. The advantages of biogas express mixtures are:
Good value for money! The grassland premium adjusted for arable land cuts the production costs per tonne of grass silage. This means that grasses have caught up considerably with maize from a financial point of view.
Using grasses in biogas plants is a more flexible approach. As they spend longer in the fermenter, the crops can later be fed to dairy cattle. This saves a cut without losing out on yields, saving time and expense. The clover species found in the biogas express mixtures meet the conditions of environmental programmes, which state that rotation cycles must have a certain proportion of legumes.
