Reduced the cultivation of energy crops cultivation of food?

On a frequently expressed view, which often to a negative Attitude towards Oilplantattach leads, is following in to be addressed. It reads: The Oilfruitattach ousted the food and farming therefore can not remain significant arable land claim take as a major fuel supplier to serve. This view seems plausible if one assumes that the future farming continue on the principle of monocultures based will. For a field that is only with rape at a time will be built, is obviously in the same period for non-cereal crops available. However, this view is shortened and does not take into account two aspects of rape or Oilplantattach the food production ultimately benefit:

1st Canola or other oil seed crops are (or can) excellent Previousfriute for the cereal crop immediately thereafter: the usually deep reaching and remaining in the soil root mass of considerable Oil previousfruites of soil organisms will be dismantled and is a Increasing the carbon budget and humus soil also dar. grow the roots of cereal plants mainly in the remaining root previousfruites tubes and can therefore larger floor space open. The result is significantly increased Grain yields without additional fertilizer, an experience that far disseminated and is now generally recognized.

2nd During the harvesting and processing of the decentralized rapegrain fall two valuable products: about 1000 kg / ha of the coveted rape oil (the Incidentally, when OORape also an excellent cooking oil) and more 2000 kg / ha of rapeseed cakes, which is an ideal replacement for soy meal to as feed for cattle and pigs is. Used rapeseed oil is not as edible oil, but as fuel, remains always still twice as much protein and mineralstoffreichem rapeseed cakes, the not only as animal feed, but also as human food (after a treatment) could be used. The o.g. View is but still questionable if, instead of barren monocultures, in a future diverse mixed farming (mixed fruit cultivation systems) the rule will be. In Bavaria, running for more than 7 years, very much Private promising field trials with organic farmers: wheat and Barley, peas or even be together with gold (Camelina sativa (L.) Crtz., one of the original weed flaxattach) sown, simultaneously harvested and threshing and the different seeds via Sieve easily separated The result: The yields of the two Cereals are compared with the corresponding monocultures around same (30 to 40 dt / ha), the baking quality of the grain but better (by 4% -6% higher gluten shares), so that higher prices can be. The crop yields in peas are even around 10% higher: 32.5 compared with 29.6 dt / ha The main reason: The peas at upwards Camelina surround him and can be more erntefähige pods train! In addition, the cereal-growing Camelina mixing 80-150 Gold of pleasure oil liters per hectare, the pea-growing Camelina even up to 270 Gold of pleasure oil reached liter / ha.

The remarkable increase in the Gold of pleasure oil income to the Duplicate is probably a positive synergy of the two Plant species (such as additional nitrogen supply of gold by the nitrogen-binding peas) due. Furthermore can be 200 to 540 kg / ha to feed Camelina meal than expected will.

Conclusion:

The experiments described show that no or only minor Reductions in food production with mixed fruit cultivation come, but also vegetable oil as fuel from weed in no small degree can be obtained.
