Cereals manufacturing for bio-fuel
Taking into account current proportion manufacturing - consumption the cereal manufacturing for bio- energy is done in a limited amount. The experts consider to be very important to conceive others about the fact of cereals manufacturing 1.5.-5 times more efficient way of usage that it has been currently applied. In future cereal straw can not be used as bio- fuel because it is required for soil fertility maintaining. Professionals point out that this aspect should be taken into account when using humus poor soils in South Estonian. Estonians can regard winter cereals (especially rye) straw only as a potential bio fuel resource considering farm or company allocation.
The cereal harvest growth may increase the straw importance as bio fuel. The bio energy out put may be remarkable when using more extensive cereal cultivation technology. When cereal yield increases in the future importance of straw as bio-fuel may be higher. Industry experts point out that bio - energetic result of fertilizers application in wheat cultivation is higher than their energetic equivalent. Taking into account the minimum level of harvest necessary for obtaining Estonian agriculture society donations for bio - energy culture confirms that more extensive production practices are planned to be used. Though agricultural domain specialists question such practices economic and energetic aspect efficiency.
Industry professionals think that the bio-energetic efficiency is several times lower in comparison with the one of wheat in case of oil-seed rape. The output, smaller than 13GJ per hectare prompts oil - seed rape self- cost decrease and bio - diesel manufacturing cost price growth when taking into account minimum harvest level, demanded by agricultural association.
