Opisani su čimbenici postanka i razvoja tla petrinjskog i glinskog kraja, uključujući geološko litološku podlogu, klimu, vegetaciju, ljudske aktivnosti, elementarne nepogode i ratne štete na poljoprivrednom zemljištu. Tekstom i na pedološkoj karti su navedeni i opisani tipovi i niže pedosistematske jedinice poljoprivrednog zemljišta. Procijenjena je sadašnja pogodnost poljoprivrednog tla/zemljišta za obradu. Za utvrđene vrste ograničenja pogodnosti korištenja tla, preporučene su agro ili/i hidrotehničke mjere. Detaljnije raspravljamo o preporukama za održavanje plodnosti tla., Factors of soil origin and development of Petrinja and Glina region are described, including geological lithological background, climate, vegetation, human activities, natural disasters and war damage to agricultural land. The types and lower pedosystematic units of agricultural land are listed and described in the text and on the pedological map. The current suitability of agricultural soil / land for cultivation has been assessed. For the identified types of soil limitations for cultivation, agro and / or hydrotechnical measures are recommended. We discuss in more detail the recommendations for maintaining soil fertility.

This study investigates multi-element composition of soil, mosses and mushrooms from a pristine temperate rainforest (Prasnik, Croatia). Additionally, the activity levels of natural (238U, 235U and 232Th decay chains, 40K and 7Be) and anthropogenic (137Cs and 134Cs) radionuclides in the investigated soil samples, obtained by gamma spectrometry, provide baseline of environmental radioactivity levels in this area. The aim of investigation was to explore the uptake of metal(loid)s by bioindicator species (mosses, mushrooms) growing in a pristine environment characterized by naturally elevated concentration of metals. The calculated enrichment and bioaccumulation factors, correlations between different groups of elements and similar multi-element patterns in mosses, mushrooms and soil samples revealed the prevailing influence of the local substrate geochemistry on element concentrations in mosses and mushrooms. The results suggest atmospheric deposition of Bi, Cd and Pb, while radionuclide activities point to atmospheric fall-out (including global contamination by radiocaesium) and influence of the pedological substrate. The confined area of investigation, with limited variations in soil characteristics and geological composition, allowed clearer insight into the origin of metal(loid)s in mosses and mushrooms. On the other hand, using bioindicator species with different element uptake mechanisms enabled distinction between different sources of elements.

SažetakU razdoblju od 2011. do 2013. godine u Hrvatskom šumarskom institutu načinjena je zbirka monolita najvažnijih šumskih tala. Zbirka je izrađena novom metodom pričvršćivanja pomoću epoksidne smole. Nakon što se iskopa pedološka jama, pripremi se čelo profila i načini se prizma tla dimenzije 20 cm X 100 cm i debljine 5 cm. Prizma se podijeli na razmake od po 10 cm. Podjela nam je potrebna zbog što vjernijeg prenošenja tla na podlogu načinjenu od vodootpornog drveta i ograničenu letvicama 2 X 3 cm. Oštrom alatkom se odvoji dio tla (oko 10 cm) i prenese u okvir koji mora biti položen horizontalno, a u njemu je premazan sloj epoksidne smole debljine do 1 cm. Nakon što se malo prosuši na zraku, monolit se učvršćuje s bezbojnim mat lakom i nakon toga se može prikazati u okomitom položaju ili objesiti na zid nekog izložbenog prostora. Nova metoda je jednostavnija i brža jer nije potreban masovni monolit u sanduku koji je teško ponekad transportirati do prve prometnice., In the Croatian Forestry Institute a collection of monoliths of the most important forest soils was produced during the period from 2011 to 2013. The collection was made by means of a new method of attachment and preparation with the use of epoxy resin. After digging the pedological pit, the profile is prepared and a prism of soil, measuring 20 cm x 100 cm and 5 cm thick, is made. With a sharp tool it is then separated from the soil and placed horizontally so that the monolith can be analysed and fixed onto the base. In the case of skeletal soils we gradually move the soil from the marked prism in the pedological profile into the frame according to marked parts. After drying the monolith is fixed with clear matte varnish, following which it can be presented in a vertical position or on the wall of an exhibition area. The new method is less complicated and faster because it does not require a massive monolith in a large box, which is occasionally difficult to transport to the first communication road.
