Šumarski list SL´PLliMLNT 12005). 238-239 Niže navedeni referati održani na Međunarodnom skupu o protucroziji i vodozaštiti nisu tiskani u Zborniku budući da su istraživanjajoš uvijek u tijeku te se daju samo njihovi sažeci u obliku kako su poslani Uredništvu. The papers listed below were presented at the International Conference on Anti-Erosion and Water Protection but are not contained in the Proceedings since research is still under way. Only the summaries have been printed in the form in which they were sent to the Editorial Board. PEDOFIZIOGRAFSKI ODNOSI NA POLIGONU ZA ISTRAŽIVANJE EROZIJE U ABRAMIMA Nikola PERNAR, Danko HOLJEVIĆ, Josip PETRAŠ, Darko BAKŠIĆ SAŽETAK: U ovom radu dajemo prikaz istraživanja koja smo započeli na pokusnom poligonu za istraživanje erozije tla "Abrami". Cilj istraživanja je analizirati recentne pedofiziografske odnose na pokusnim plohama, uspostavljenim u cilju testiranja nekoliko metoda biološko-tehničke sanacije erozije, da bi se ocijenila njihova primjenjivost na istarskom flišu. Poligon za istraživanje erozije tla pored naselja Abrami u Istri uspostavljen je 1956. godine, kada su provedena i temeljita pedološka istraživanja. Ista su pokazala da su plohe uspostavljene na dvije skupine tala, različito zahvaćenih erozijom. Radilo se o eutričnim kambisolima, izloženim i karbonatnim rendzinama, sirozemima, erodiranim rendzinama i kambisolima te o koluvijima. Istraživanjima smo zamislili obuhvatiti najvažnije pokazatelje evolucije tla u razdoblju postojanja pokusa, a to je stratigrafija profila tla, pH vrijednost po horizontima, zaliha i distribucija organske tvari tla, sadržaj dušika, fosfora i kalija te stabilnost strukturnih mikro i makro agregata. Prvi nalazi upućuju na promjene ujiziografiji tla u odnosu na nulta stanja, koja se bitno razlikuju po plohama. To se posebno zapaža u formiranju i stabilizaciji O- i A- horizonta te agregatne strukture. K lj u č n e r ij e č i: erozija tla, evolucija tla |

N. Pernar. D. Iloljcvić. J. Petras, D. Bakšic: PEDOFIZIOGRArSKI ODNOSI NA POLIGONU ... Šumarski list - SUPLEMENT (2005), 238-239 PEDOPHYSIOGRÄPHIC RELATIONS IN THE EROSION TESTING SITE OF ABRAMI Nikola PERNAR, Danko HOLJEVIĆ, Josip PETRAS, Darko BAKŠIĆ SUMMARY: The paper deals with research in the experimental soil erosion research site of "Abrami". Research was aimed at analysing recent pedophysiographic relations in sample plots established for the purpose of testing several methods of biological- technological erosion regulation so that their applicability to Istrian flisch could be assessed. The testing site for soil erosion research near the village of Abrami in Istria was established in J 956, when detailedpedological research was carried out. The research showed that the plots were set up on two soil groups differently affected by erosion. The soils in question were eutric cambisols, dealkalised and carbonate rendzinas, regosols, eroded rendzinas and cambisols, as well as colluviums. Research was intended to comprise the most important indicators of soil evolution throughout the duration of the test. These include the soil profile stratigraphy, pH values per horizons, stock and distribution of soil organic matter, nitrogen, phosphorus and potassium content, and the stability of structural micro and macro aggregates. Initial results point to changes in soil physiography in relation to the zero state, which differs fundamentally from plot to plot. This is particularly visible in the formation and stabilisation ofO and A horizons and in the aggregate structure. Key words: soil erosion, soil evolution |
