Pseudogley soils in Slavonia and Baranja

U radu su analizirani rezultati fizikalno-kemijskih svojstava pseudoglejnih tala na podruĉju Slavonije i Baranje. Odabrano je 30 lokacija na terenima s nadmorskom visinom od 134 do 257 m. Utvrđena je niska razina plodnosti zbog ograniĉavajućih uĉinaka nepovoljnih kemijskih i fizikalnih svojstava. Istraţivani pseudogleji su ekstremno kisele do kisele reakcije (pH(KCl) = 3,74 - 5,14 u oraniĉnim slojevima), slabo do umjereno humozni (0,06 – 2,89 % humusa), a opskrbljenost biljkama pristupaĉnim oblicima fosfora i kalija je siromašna do dobra. S obzirom na povećani sadržaj gline u podoraniĉnom sloju prisutan je problem slabijeg procjeđivanja oborinskih voda uz umjerenu do visoku zbijenost. Sve rezultira stagnacijom vode na površini, manjkom zraka (vrlo niska aeriranost) i problemima u rastu biljaka. U oba sloja (0 – 30 cm i 30 – 60 cm) mogu se uoĉiti pozitivne i negativne korelacije između određenih svojstava pseudoglejnih tala.In this thesis the results of physical and chemical properties pseudogley soils in Slavonia and Baranja are analysed. 30 locations have been selected with altitude ranging from 134 to 257 m. Low fertility levels have been determined due to the restrictive effects of adverse chemical and physical properties. The investigated pseudogley soils have shown extremely acid to acid reaction (pH (KCl) = 3.74-5.14 in arable layer), low to moderately humic (0.06 – 2.89%), and the plant supply to accessible forms of phosphorus and potassium is poor to good. Given the increased content of the clay in the sub-arable layer, there is a problem of weaker filtering of rainwater with moderate to high density. It all results in stagnation of water on the soils surface, air shortage (very low aeration) and problems in plant growth. In both layer (0 – 30 cm and 30 – 60 cm) positive and negative correlations can be observed between certain properties of pseudogley soils
