Digestate is a liquid residue from anaerobic digestion in biogas plant. Digestate contains a high proportion of mineral nitrogen and other macroelements and microelements necessary to plant growth. Recycling of nutrients contained in digestate back to the soil is considered as the most suitable utilization of digestate. The digestate used in experiment was taken from agriculture biogas plant which uses pig manure and corn silage as input raw materials. This paper presents the results of laboratory pot experiment including the results of soil analysis and effects of using whole digestate and digestate and haylage mixture to underground and aboveground biomass of wheat (Triticum aestivum). We have chosen 10:1, 5:1 and 3:1 weight ratios of digestate and haylage and we have observed their inhibitory or stimulatory influence on roots and stems. We have recorded the highest root inhibition using whole digestate, highest root stimulation using digestate ? haylage weight ratio 3:1 and the highest stem stimulation using digestate ? haylage weight ratio 5:1.
