| Description
| - In 2008 and 2009 total and water-soluble levels of some heavy metals (Zn, Cu, Co, Pb, Cd and Mo) were explored in soils of permanent grasslands of the foothills of the Hrubý Jeseník Mts. Relationship between soil reaction and content and quality of organic matter was studied. The total content of heavy metals ranged from 38.40 to 71.65 mg Zn.kg-1; 10.47- 17.46 mg Co.kg-1; 14.30 - 41.42 mg Cu.kg-1; 3.84 - 15.53 mg Pb.kg-1; 0.104- 0.323 mg Cd.kg-1; 0.129 - 0.617 mg Mo.kg-1. Content of water-soluble forms ranged from 0.0016 to 1.0100 mg Zn.kg-1; 0.0204 - 0.2605 mg Co.kg-1; 0.0085 - 0.2413 mg Cu.kg-1, and 0.0108 - 0.0485 mg Cd.kg-1 / soil. Soil reaction ranged from 4.09 to 5.43 (i.e. from extremely acid to acid). Results showed that decreasing of pH caused increasing of water-soluble fractions of zinc and cobalt significantly, especially when mineral and organic fertilisers (slurry) were applied. After compost application the inverse relationship water-soluble zinc content and pH was found. Results were not statistically significant in this case. On permanent grassland soils total organic carbon (TOC) content ranged from 0.60 to 2.55 %. Sum of humic substances (HS) ranged from 4.5 to 8.0 mg.kg-1; with a 1.5 -- 3.3 mg.kg-1 and 2.5 -- 5.5 mg.kg-1 proportion of humic acids (HA) and fulvic acids (FA), respectively. Humification degree was low (< 20 %). After organic and mineral fertilizers application on permanent grassland soils we discovered statistically significant differences in TOC and HA (compost) content (between the individual rates of organic fertilisers). Because of FA prevailed in humus fractional composition they mostly contributed to the transformation and migration of heavy metals mobile forms. During the experiment with mineral and organic fertilisers the dependence of water-soluble heavy metals and organic matter content was statistically significant for cobalt and copper. Cobalt content was inversely proportionate to HA content (r = -0.4021). In a sim
