PEDOPHYSIOGRÄPHIC RELATIONS IN THE
EROSION TESTING SITE OF ABRAMI

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
