Activators of biological transformation and their effect on pig manure quality and barn condition aggregate

Popis výsledku v původním jazyce

In order to reduce the consumption of industrial fertilizers used in agriculture, production of higher quality pig manure acting as their partial substitution should be enhanced. The production involves utilization of the agents on the basis of organic matter biological transformation activators. The objective of this paper is to verify the efficiency of such an agent, i.e. Z'fix, from the viewpoint of the barn condition parameters, of the pig manure quality and manure nutrient content, and mainly from the viewpoint of ammonia emissions. From January 2018 to January 2019, 80 samples of pig manure were collected in a farm with the total of 84 livestock units (LU), where 1 LU = 500 kg live weight (L.W.). On the farm, the pigs were stabled in 2 barns with straw bedding, and with 2 pens each. In the first barn, the agent Z'fix was applied, the second one represented a control. In each barn, fattening pigs were divided in 2 pens (40-70 +- 5 kg and 70-110 +- 5 kg L.W.). The frequency of pig manure removal varied from 150 to 180 days. An accredited laboratory examined the manure chemical parameters. Ammonia emissions were evaluated every two weeks (Data Logger NH3 apparatus measuring 25 cm above the bedding surface during 48 hours). With regard to the pig manure production, the results confirmed (P < 0.05) that the treatment of the straw bedding by the Z'fix agent had a positive influence on the pig manure quality, the course of the fermentation process, and on the microclimate in the barn. Compared to the control (without Z'fix application), higher contents of the following compounds were found: NNH4+ (by 54 %); N (by 37 %); K2O (by 10 %); P2O5 (by 46 %). Furthermore, maximum humidity decreased by 10 % and the pH value increased from 8.7 to 9.1. Finally, maximum levels of the mean ammonia emissions in the barn decreased by 38 %. In agreement with the requirements posed by the Gothenburg Protocol, the agent's utilization is desirable considering its contribution to ammonia emission reduction and pig manure production quality enhancement.
