20.500.12556/DKUM-41110 VPLIV GNOJENJA S FOSFORJEM IN KALIJEM NA SPREMEMBE V RASTLINSKI SESTAVI EKOLOŠKEGA TRAVNIKA V LETU PRVE APLIKACIJE GNOJIL Influence of fertilization with phosphorus and potassium on the plant community of the ecological meadow in the first year of application V travniškem poskusu smo od marca 2002 do oktobra 2002 proučevali vpliv gnojenja s fosforjem in kalijem na spremembe v rastlinski sestavi ekološkega travnika v letu prve aplikacije gnojil. Poskus smo izvajali na posestvu Jergač na Libeliški gori (S zemljepisna širina 46º 36' 12'', V zemljepisna dolžina 14º 55' 57'', nadmorska višina 840 m) v občini Dravograd. Poskus smo zasnovali kot latinski kvadrat z osnovno parcelico 8 x 8 m. Obravnavanja (gnojenje je bilo spomladi) v poskusu so bila: A – kontrola (brez gnojenja), B – 390 kg surovega fosfata ha-1, C – 281 kg kalijeve soli ha-1in D – 125 kg P2O5 ha-1 in 112 kg K2O ha-1. Ugotovili smo, da v letu prve aplikacije gnojil posamezna obravnavanja niso statistično značilno vplivala na botanično sestavo. Za vidnejše vplive gnojenja bi morali poskusno površino gnojiti več let. From March 2002 to October 2002 the influence of the fertilization with phosphorous and potassium on the plant community of the ecological meadow in the first year of application was studied. Field trial was carried out at the Jergač farm on the Libeliška gora (N latitude 46º 36' 12'', E longitude 14º 57' 57''), municipality Dravograd at the 840 m above sea level. The trail was designed as latin square with the single plot of 8 x 8 m. Treatmens (spring fertilization) were carried out on four levels A) no fertialization (control), B) application 390 kg raw phosphate per ha, C) application of 281 kg of potassium salt per ha , D) application of 125 kg P2O5 per ha and 112 kg K2O per ha. The results of the first year study showed no statistically significant influence of the fertilization on the botanical composition of the experimental plots. The experiment should be repeated for more years to obtained reliable results of the influence of fertilization on the botanical composition of the ecological meadow.
