Abstract:Poskus vrednotenja vpliva kalcijevih gnojil na lastnosti tal ter mineralno sestavo plodov je potekal v letih od 2004 do 2006 na posestvu UKC Pohorski dvor. Vključeni sta bili sorti jabolk 'Gala' in 'Braeburn'. Kalcifikacija tal je bila izpeljana jeseni leta 2004 in 2005 z različnimi odmerki kalcijevih gnojil. Poskus s sorto 'Gala' je vključeval gnojenje s 5 t sadre/ha, 10 t sadre/ha, 15 t sadre/ha, 20 t sadre/ha in 20 t hidriatiziranega apna/ha ter nepognojeno kontrolo. Poskus s sorto 'Braeburn' je vključeval gnojenje s 15 t sadre/ha, 20 t sadre/ha, 25 t sadre/ha in 20 t hidratiziranega apna/ha ter nepognojeno kontrolo. V poskusu smo želeli ugotoviti vpliv sadre na reakcijo tal, dostopnost hranil, predvsem kalcija v tleh in vpliv različnih načinov kalcifikacije na mineralno sestavo plodov. pH tal se je povečal po enkratni kalcifikaciji tal z apnom pri sorti 'Braeburn' za 15 % in pri sorti 'Gala' za 71 %. Po dvakratni kalcifikaciji z apnom se je pH tal v nasadu dreves sorte 'Gala' povečal za 80 %. Uporaba apna (20 t/ha) je povečala koncentracijo Ca v plodovih sorte 'Braeburn' za 16 %, medtem ko uporaba drugih kalcijevih gnojil tega učinka ni imela. Pri sorti 'Gala' je bil vpliv kalcifikacije na povečanje koncentracije Ca v plodovih manj izrazit.

Title:The application of gypsum in an orchard
Abstract:At the Agricultural Centre Pohorski dvor we carried out a field trial aimed at evaluation of the effect of calcium fertilizers on soil properties and mineral composition of fruits in the years from 2004 to 2006 on cv. Gala and cv. Braeburn. The soil calcification with different quantities of calcium fertilizers was performed in the autumns of 2004 and 2005. With cv. Gala our trial included fertilization with 5 t of gypsum/ha, 10 t of gypsum /ha, 15 t of gypsum /ha, 20 t of gypsum/ha, 20 t of hydrated lime, and Control. The trial with cv. Braeburn included fertilization with 15 t of gypsum/ha, 20 t of gypsum /ha, 25 t of gypsum /ha, 20 t of hydrated lime, and Control. The aim of our trial was to establish the impact of gypsum application on the soil reaction, availability of nutrients, especially calcium, and the effects of various ways of calcification on the mineral composition of fruits of both cultivars. In cv 'Braeburn' pH in the soil was increased by 15 % and by 71 % in cv 'Gala in case of one application of hydrated lime. In case of two applications of hydrated lime, pH in cv. 'Gala' was increased by 80 %. The application of hydrated lime (20 t/ha) increased the Ca concentration in the apples of cv. 'Braeburn' by 16 %, while this effect was not achieved by the application of other calcium fertilizers. In cv. 'Gala' the effect of calcification on the increase of Ca concentration in apples was less significant.
