plays some facts: In 2007
were used 17% of German farmland for the cultivation of energy crops. The main use for energy recovery plant in biogas plants of maize, of sending you is not quite ecologically sound, because of increased corn production can promote soil erosion negative. Currently, at about 1.65 million. ha (maize for food and feed production is not included) corn grown for energy recovery.
The cultivation is usually done by the plow, is also harvested using heavy machinery, This results in damage to the soil structure.
Sowing takes place before the end of April or early May, as the young growth is very slow, the soil a long time is not adequately protected from erosion.
corn is usually planted in row crops, this is problematic, because the soil is not planted in vegetation gaps is permanently unprotected. Unfortunately
be grown more and more monocultures. A two-crop system, however, can reduce soil erosion. It is during the winter growing a first culture, in the summer, the second culture (maize). This has the advantage that is reduced by the almost year-round ground cover, erosion, and also the income resulting from the initial culture.
Another not to be underestimated, is the height of up to 2.5 m, and its increased production. Here, similar problems arise as in the wind: Not In My Back Yard! Some corn acres are still to tolerate, but who wants to pass on his bike tour in the summer only to corn fields, where nothing else just looks. In some regions of the maize makes up 50% of arable land. It ultimately comes to a serious deterioration of the landscape. Therefore called NABU and DVL (German Association for Nature Management) in 2006, a restriction on the proportion of maize for biogas plants at 50% and increased cultivation of mixed cultures.
