The Use of Organic Fertilizers in Integrated Production of Apples

V Sadjarskem centru Maribor in Univerzitetnem kmetijskem centru Pohorski dvor smo v letu 2007 izvedli poskus gnojenja z gnojili Biosol in KAN pri sorti \u27Gala\u27. Uporabljali smo različne količine gnojil, ki smo jih odmerjali v dveh obrokih: 1. obravnavanje: standardno gnojenje po IP 335 kg KAN/ha, 2. obravnavanje: jesensko gnojenje z ekološkim gnojilom 1.125 kg Biosola/ha, 3. obravnavanje: jesensko gnojenje s 167 kg KAN/ha in 625 kg Biosola/ha, 4. obravnavanje: spomladansko gnojenje z ekološkim gnojilom 1.125 kg Biosola/ha, 5. obravnavanje: spomladansko gnojenje s 167 kg KAN/ha in 625 kg Biosola/ha. V Univerzitetnem kmetijskem centru v Pohorski dvor pri Mariboru, kjer so tla bogato založena z organsko snovjo (5,1 %), je bil statistično dokazljivo najboljši rezultat tako glede količine kot kakovosti pridelka pri spomladanskem gnojenju, 4. obravnavanje. Sklepamo lahko, da je na tleh, ki so bogato založene z organsko snovjo, najboljše gnojiti spomladi s 1.125 kg Biosola/ha. V Sadjarskem centru Maribor, kjer so tla srednje založena z organsko snovjo (2,6 %), so bili statistično dokazljivo najboljši rezultati tako glede količine kot kakovosti pridelka jabolk v obravnavanju 2. Sklepamo lahko, da je pri tem tipu tal in pri tej sorti najboljše jesensko gnojenje z ekološkim gnojilom 1.125 kg Biosola/ha.In the year 2007 we implemented the attempt of fertilizing with the biosol and KAN on the ‘Gala’ sort. This attempt was carried out in the Fruit growing centre Maribor and University centre of Agriculture in Pohorski dvor. We used different amount of fertilizing agents, which were measured in two rations: 1. tre.: standard fertilizing with IP 335 kg KAN/ha, 2. tre.: Autumn fertilizing with organic fertilizers 1.125 kg Biosol/ha, 3. tre.: Autumn fertilizing with 167 kg KAN/ha and 625 kg Biosol/ha, 4. tre.: Spring fertilizing with organic fertilizers 1.125 kg Biosol/ha, 5. tre.: Spring fertilizing with organic fertilizers 167 kg KAN/ha and 625 kg Biosol/ha. In UC of Agriculture in Pohorski dvor, where the ground is highly rich with organic substance (5.1 %), results showed statistically best effects, considering the amount and the quality of the harvest, during 4. tre. in spring. We came to the conclusion that the most proper timing for fertilizing is in spring with 1.125 kg biosol/ha. In the Fruit growing centre Maribor, where the ground is medium enriched with organic substances (2.6 %), the best results were statistically showed, considering the amount as well as the quality of apples, in autumn fertilizing with mineral fertilizers (2. tre.). We came to the conclusion that with this type of ground and sort, fertilizing in autumn with organic fertilizers 1.125 kg Biosol/ha, brings out the best results
