Sažetak
Far as is known there is no relevant information about the status of total and organic phosphorus in Croatian soils, so aim of this study was to determine the total and organic phosphorus in soils of the eastern Croatia. In total were collected 94 soil samples and the soil pH, organic matter as well as the total phosphorus content and organic phosphorus content were analyzed. All samples were grouped according to soil pH and organic matter in two groups (pHKCl <6, pHKCl > 6, organic matter< 2%, organic matter> 2%). Analyzed samples showed significant amounts of total phosphorus with minimal content of 329.84 mg P2O5 kg-1, while the maximum value determined by the total phosphorus was 1732.19 mg P2O5 kg-1 with an average of 713.03 mg P2O5 kg-1. The content of organic phosphorus in soils ranged from 3, 44 mg P2O5 kg-1 to 292, 55 mg P2O5 kg-1, with the portion of organic phosphorus in total phosphorus from 0.54% to 78.29%.. Seen from the humus content in the soil, very low humic soil had an average of 12.0% of organic phosphorus, while fairly humic soil had an average of 7.1% organic phosphorus. Also, the results showed that the minimum (0.54%) and maximum (78.29%) portio of organic phosphorus in total phosphorus soils recorded within broad categories humic poor soils. Although it was expected, there was no significant differences between the amount of organic phosphorus in soil and organic matter content, but large influence of organic matter content to the correlation of certain fractions of phosphorus in the soil were determined (r = 0.89).
