Based on the results of other agrochemical analysis given intable 2 the values of pH ranged from 2.8 to 3.4, what proves of thefact the soils remains very acidic even after adding conditioners.Also the values of Ca content confirm unfavourable state of soil inrelation to soil reaction as well as the process of forming high qualityhumus. Maximal value of Ca content reached 0.04 g per 1 kg whatproves that soils are slightly calcareous.Table 2 Results of agrochemical soil analyses after applying soilconditionersHumus content reached very high values. They ranged from4.9% up to extreme 13.2%. With regard to high acidity and very lowcontent of Ca humus the quality was not high. Also the values of C:N ratio partially confirms that, because they are higher and rangefrom 13 to 21. Either in one case they are not higher than 25 whatindicates that there may occur still in the soil release andaccumulation of ammoniac nitrogen through ammonificationmicroflora. Also the values Nt confirm that providing we evaluatethem out of the context of other soil properties, especially the ratioC: N. Thus we may state the soil has moderate up to very highsupply of nitrogen. The evaluated soils have permanently very lowsupply of phosphorus, and content of magnesium may be also~ 265 ~
