Cím:	The effect of bacteria fertilizers on the nitrogen amount extracted by the yield of perennial ryegrass (Lolium perenne) on different soil types / Ida Kincses, Marianna Sipos
Dátum:	2008
Megjegyzések:	In our comparative experiment we studied the effect of bacteria fertilizers Bactofil A10 and Biorex 1 and 2 on the nitrogen amount extracted with the yield on three soil types (a chernozem from Debrecen - Látókép, an acidic sandy soil from Nyíregyháza and a neutral sandy soil from Józsa) with perennial ryegrass (Lolium perenne L.) as a test plant. From our results it can be stated, that that the nitrogen amount extracted by the yield is the highest in plants grown on the sandy soil from Nyíregyháza, while it is the smallest in plants grown on the sandy soil from Józsa. Bacteria fertilization increased the nitrogen amount extracted by ryegrass on the calcareous chernozem soil (Látókép). This effect was also proven by the statistical analysis. On this soil type the different bacteria fertilizers had similar positive effect on nitrogen mobilization. On the sandy soil from Nyíregyháza adding Bactofil A10 resulted in a significant reduction of the extracted nitrogen amount. The bacteria fertilizer product Biorex has not any positive effect either. As our results show, on this acidic soil type with such low humus content, the bacteria that got into the soil with the fertilizer could not proliferate, therefore they couldn't fulfil their biological tasks. On the neutral sandy soil from Józsa with low humus content, the bacteria fertilization increased significantly the nitrogen amount extracted with crop plants from soil. A statistically significant positive effect was proven in case of the application of Bactofil A10 and Biorex1-2 fertilizers as well. As our results show, on this soil type there is no need to apply a higher dosage of fertilizer for enhancing the nitrogen mobilization. In our experiment the fertilizer Biorex-2 had a higher effect on the extracted nitrogen amount, than the recommended combination of Biorex -1 and -2 fertilizers. The reason for that is probably the application of for the nitrogen cycle important bacteria species that are applied to soil with Biorex-2.
