Humus content and acidity of dominant soil types in the Pannonian agroregion of Croatia
As a conditionally renewable natural resource, soil has a crucial and irreplaceable impact on the sustainable development of world economy, particularly sustainable agriculture, and on the environmental protection. The main objective of soil management is its protection from all forms of damage, especially from soil degradation. Particularly unfavorable degradation processes in Croatia are dehumification and soil acidification. In order to protect the soil from further dehumification and acidification, this paper presents the state humus content and acidity of the three dominant soil types found on agricultural land in the eastern, central, western and northwestern Croatian agricultural sub-regions. Climatic conditions of these sub-regions are characterized by equal values of average annual air temperature and a significant reduction in average annual rainfall from west to east - precipitation is highest in the northern sub-region (1014 mm) and smallest in the eastern sub-region (687 mm). Humus content in all three soil types in all sub-regions is very low (less than 3%) and increases from east to west, which correlates with the increase of precipitation. Highest humus content was found in Pseudogley soil type, and lowest in Luvisol. Average pH values (M KCl) of the plough horizon variate in Eutric Cambisol from 5, 97 to 4, 64, in Luvisol from 4, 80 to 4, 30, and in Pseudogley from 4, 60 to 4, 16 (the lowest values were determined in the northwestern sub-region, and the highest in the eastern sub-region). In all soils there was a pH increase with depth, as a consequence of parent material properties and debasification of surface soil horizons.
