Abstract

Crvenica (terra rossa) je tipično tlo Mediterana, najčešde na vapnencu. U Istri je jako zastupljena i korištena za poljoprivredu. Zbog dugotrajnog postanka, izvor je podataka za razumijevanje prošlih i predviđanje bududih okolišnih promjena. Analizirana je mikromorfologija reprezentativne crvenice, uvažavajudi i njene fizikalno-kemijske značajke. Utvrđen je sklop profila AE-Bt1-Bt2-Bt3-Bt4 uz dosta homogene značajke duž 225 cm dubine. Kontinuirana glinovitost i strukturiranost tla ukazuju na oglinjavanje, uz formiranje strukture i rubifikaciju kao ključne pedogenetske procese. S dubinom raste zastupljenost prevlaka željeza i gline, što ukazuje i na proces lesivaže. Dio nodula Fe, prevlaka gline i uklopina je uputio na reliktnost, tj. poligenezu tla. Profil je klasificiran prema WRB-u kao Hypereutric Luvic Rhodic Nitisol (Humic). Kako su Nitisoli tipično tropska tla, potvrđuje se da su crvenice Istre vedinom recentno-reliktna tla, uglavnom nastala u okolišima bitno drukčijima od današnjih.

Abstract (english)

Terra rossa is a typical Mediterranean reddish soil, mostly on limestone. It's widely spread in Istria and used in agriculture. Due to long-lasting genesis, it provides data for understanding past and predicting future environmental changes. Micromorphology of representative soil profile (AE-Bt1-Bt2-Bt3-Bt4) was analysed considering also its physical/chemical properties. Its features were rather homogenous along 225 cm depth. Continuous clay content and soil structure indicate argillization including structure, formation and rubification as key pedogenic processes. Contents of Fe and clay coatings increase with depth, indicating lessivage. Many Fe nodules, clay coatings and intercalations appeared as relict, pointing to polygenesis. Profile is WRB-classified as Hypereutric Luvic Rhodic Nitisol (Humic). As Nitisols are typically tropical soils, it's confirmed that Istrian terra rossa are mainly recent-relict soils formed in environments significantly different than the present ones.
