MENDELNET 2013RESULTS AND DISCUSSIONThe soil type which was selected is chernozem on loess. Fig. 1,Total porosity - top of the slope (A)Plots are pitched and intensively farmed.Porosity:The values of total porosity at the top ofthe slope (Fig. 1) in the topsoil horizon are50,00around 45% on two of the plots. This value45,00is on the edge of porosity state, which isevaluated as good. On the remaining plots, %40,00the topsoil porosity is unsuitable. In the35,00subsoil, the value of the porosity is close to30,00the 45 % limit, except for the first plot,where the state porosity is unsatisfactory.25,00In the loess horizon the situation is similarto the subsoil, on the first plot the porositystatus fell below 39% - the status evaluated as non-structural.In the centre of the slope (Fig. 2), the valueof porosity is in the range of 44-48 %, i.e.close to the boundary of being good.Condition is unsatisfactory in the subsoil ofthe first, second and third plot where thesubsoil is already in the loess .In the position under the slope (Fig. 3) thestate of total porosity is unsatisfactory,even non-structural, except for the first andsecond plot, where the state in the topsoil isgood.Density:Density indicates mellowness or settlenessof the soil. The measured values rangedfrom 1.38 to 1.6 g.cm -3 and correspond tothe porosity values described above.55,0050,0045,0025,00Total porosity - (top of the slope = A)Dambořice1 Dambořice2 Klobouky u B.1 DomanínTotal porosity - (slope = B)arable layersubsoilloess 1-10% 40,00arable layersubsoil35,00loess 1-1030,0055,0050,0045,00% 40,0035,00Fig. 2, Total porosity – slope (B)Dambořice1 Dambořice2 Klobouky uB.1DomanínFig. 3, Total porosity – under the slope (C)Total porosity - (under the slope = C)arable layersubsoil30,0025,00Dambořice1 Dambořice2 Klobouky u B.1 Domanín298 | P age
