In addition to energy-raw material processing of increased efficiency, new opportunities open for plant type’s selection and for harvesting date timing due to the new method. Since, owing to the new technology, segregation of plant varieties becomes necessary, in the course of microbiological degradation however plants those so far were incapable for biogas appliances- could also have been used for those purposes.
The opportunity for two-cultured exploitation may have been created with good soil quality and sufficient rainfall, so in this case a multiple-harvest of two plant types happens. Foremost, in autumn frost-resistant plant kinds varieties are grown such as winter cereals grass types, rape, carrot, peas or fodder flax.They are harvesting in the period of the highest biomass-contain, in other words, some weeks before seed maturation. Arable weeds could also be tolerated, since on the one hand, they contribute to gross biomass contain, an on the other hand if they are harvested early enough together with other industrial crops, they hinder their reproduction in addition to seed scattering. We could totally forget about insecticides, just as about the use of fungicides or pesticides since their positive yield increasing impacts above all is based on defence against diseases and pests, but most of all during the maturing phase. Vegetation time could be gained throughout the early ingathering of the first crops from which the raising of the second culture gains profits.Second cultures are thermophilic kinds, such as corn, sunflower, millet or hem. They are sow in June, and are reaped in October. All types of first and second crops may be grown with arbitrary species amalgamation. The whole year long vegetation-covering and the constant nutrient withdrawal that is connected to this reduce the nutrient getting into the soil and drinking water. Sagar places of abandoned cultivation two-cultured plantations may be seeded in direct seeding among the green crops’ stubble, thus soil erosion is also avoidable.
