Activators of biological transformation and their effect on manure quality
Original language description
One of the possibilities how to improve the soil characteristics is to increase the production of the high quality farmyard manure with the utilization of the agents on the basis of the organic matter biological transformation activators. The aim of this paper is to verify the agent Z fix efficiency from the viewpoint of the farmyard manure quality, of the barn conditions parameters, mainly to decrease ammonia emissions. A total number of 90 samples of farmyard manure was collected from January to December 2017 in 2 farms (total 230 LU, where 1 LU = 500 kg L.W. young cattle 300 500 kg live weight (in each barn) from suckler cows breeding system). Chemical parameters were tested in accredited laboratory. On each farm, the animals were stabled in 2 barns (straw bedding) the first barn with agent Zfix application the second one as control. The removal frequency of manure was 6 8 weeks. Ammonia emissions were measured in 10 day intervals (Data Logger NH3 apparatus) measuring 25 cm above the bedding during 2 hours. Our results confirmed that the agent Zfix application (P 0,05) on the straw bedding by the farmyard manure production had a positive influence on the fermentation process and the farmyard manure quality and on the microclimate in the barn. In contrast to the control, higher contents (with Zfix application) of the following compounds were found N (by 15 prc.) N NH4 (by 34 ) P2O5 (by 42 ) K2O (17 ) and pH value increased from 8,6 to 9,3. It was found the decrease of the maximal mean ammonia emissions in the barn by 35 compared to the control. The application of the agent and its contribution to ammonia emissions and farmyard quality is in agreement with the requirements of the EU and with the Gothenburgs Protocol.
