Effect of alcohol on bards agrochemical soil properties

Abstract

The influence of distillery stillage doses on the yield of wheatgrass hay on agrochemical properties of soils in general is considered in the article. The most effective dose of distillery stillage under existing conditions is revealed. Nitrogen is the decisive factor for the yield of the crops. Widespread deficiency of nitrogen represents scientific and practical interest for the agro-chemistry studying transformation of nitrogen in soil-fertilizer-plant system for the purpose of increase in efficiency of crops quality in the biological relation. Increase in the main production of distilleries and conse-quently in waste products of the spirit industry, low demand from cattle breeders on the distillery stillage (feeding of cattle with distillery stillage is precisely connected with seasons, i.e. it is fed, mainly, during the stall period) has led to the fact that nearly 50% of it could not be sold. Development and deployment of new waste-free technologies of production of alcohol will demand a lot of time and expenses, and the unused stil-lage comes to ponds stores daily which are gradually overflowed that endangers the ecological condition of croplands and open reservoirs, adjacent to distilleries. Moreover, long storage in ponds leads it to spoiling, stratification and formation of a ground deposit. Therefore the problem of stillage utilization is very actual now and demands an integrated approach to its consideration as it has to be considered in the economic point of view, and from compliance to requirements of the nature protection legislation. One of the solutions of the problem stillage utilization is its application in agriculture as fertilizer. In Ukraine, the grain bards resources are quite significant, given the volume of alcohol SE Ukrspirt. The volume pislyaspyrtovoyi bards on modern technology is per 1 dm3 alcohol 11 ... 13 dm3 bards. However, it can be stored quickly sour, costly transportation to the consumer. Reset distillery bards in the river leads to significant environmental degradation. It solids accumulate in water pipes and riverbeds, decompose and pollute the environment. To build bards were repositories (filtration fields), which naturally occurs mechanical, chemical and biological treatment of waste. In bioshari formed in a layer of filtration load, the sewage draining into the ground, organic matter biodegradable. This mechanism is similar to the process of composting cut vegetation, household food waste and so on.
