Sažetak
Maintaining a certain content of soil organic matter (SOM) is a big challenge in modern agricultural production, especially in conditions of significant climate change. The assumption is that the type of soil use significantly affects changes in soil properties, including the content of SOM. Therefore, a study was conducted comparing the changes in soil properties on arable land and in perennial plantations (orchards and vineyards) over a 15-year period. The 1, 000 average soil samples (depth of 0-30 cm) were selected and sampled in 2020 or 2021 based on the spatial distribution in eastern Croatia from the same coordinates as 15 years earlier (2005 or 2006) on arable land (778 samples) or permanent plants (222 samples). The soils sampled in 2005 and 2006 were strongly acidic to alkaline (pHKCl 3.54-8.33 ; pHH2O 4.14-8.56) with SOM content 0.98-5.48% (average 2.21%). The range of SOM content in arable land was 1, 06-5, 48% and in orchard samples 0, 98-4, 30%. In the same soils 15 years after SOM content decreased on average from 2.21% to 2.08% (3.75% decreasing of SOM). But, there were significant differences between permanent plantations and arable lands. However, in vineyards and orchard soils, an increase in SOM content was found from an initial average of 2.09% to 2.32% after 15 years (an increase of 13.8%). On the other side, after 15 years of crops growing on arable land, the average SOM content decreased from the initial 2.24% to 2.01% (SOM content 8.78% lower). Comparing the soil classes according to SOM content, the greatest decrease in SOM (3.07 vs. 3.57%) was found on arable land with the highest initial SOM content (> 3% SOM), and the highest increase (2.03 vs. 1.68) was on permanent plantations with the lowest initial SOM content (< 2% SOM). The results lead to the conclusion that growing crops on arable land resulted in a decrease in SOM, while in permanent plantations the SOM content was most often increased.
