  • Use of machines for liquid manure aerating and mixing
    Janžekovič, Marjan, 1959- ...
    The paper is concerned about the ecological aspects of liquid manure. In order to have a better insight into the efficiency of the machine, four sample of liquid manure were analysed, namely two ... samples from a pit without aerators and two samples from a pit with incorporated aerator. The analysis showed that the dry matter content in the liquid manure amounted to 5,05 - 5,74 %. The sample, taken from the pit with incorporated aerator after 20 minutes of mixing, contained the greatest quality of the dry matter. The nitrogen and phosphorus content is equal to the average; again the sample taken out of the pit with aerator stands out. The values of potassium exceeded the European average. The aerated liquid manure is spread on the surface more uniformly, it flows faster off the plants and penetrates faster into the ground up to the roots. When the aerated liquid manure is sprinkled, the bad smell in the environment is considerately lower. Pumping into the cistern is much easier because it does not contain clods. The fodder remains are chopped and do not stop up the pipe. The cost of aeration is small in comparison with the devices for liquid manure mixing.
