The pot experiment investigated how the fertilizing value of superphosammonium (granulated mixture of ammonium sulphate and powdery superphosphate) changes compared with equivalent quantity of substrates. The evaluation of the fertilizer value was tested on acidic soil and soil limed with calcium carbonate according to single hydrolytic acidity. The plant used in the experiment was spring barley Diva cultivar. Test results show a considerable more advantageous influence of superphosammonium on the barley yield and quantity of nitrogen and phosphorus absorbed, compared with substrates from which it has been produced. This difference has been observed both in objects with and without lime. Stopping nitrification by N-Serve decreased the difference between the separately applied ammonium sulphate with powdery superphosphate and superphosammonium. The obtained results suggest, that the reason for better fertilizing action of superphosammonium is probably the decrease in the rate of nitrification of ammonium ions present in this fertilizer.
