Abstract: The aim of this paper was to verify the effect of the Z'fix (PRP Technologies, France) activator of biological transformation of manure from the viewpoint of the cowshed conditions parameters, produced manure quality, manure application effect on crop yields, and overall economics. Concerning manure production, the application of the Z'fix agent enhanced quality, structure and nutrient content (N total by 23%, P2O5 by 42%, K2O by 17%) in the manure from deep litter housing. Compared to the untreated control, differences in the nutrient content of N total and K2O were statistically significant, NH3 emissions dropped significantly by almost 35%. The economic benefit of manure production with the use of the Z'fix agent demonstrated overall savings at the level of 1,369 CZK/LU/year. The influence of manure produced combined with the PRP Sol application was tested in terms of a boost of crop yield potential of silage maize and of winter wheat. Compared to the control, both crops reached yields higher by 0.7% to 9.8%.
