Effect of soil tillage and digestate application on some soil properties

Abstract

The effect of different methods of tillage on basic physical and chemical properties of soil was tested in a pilot field experiment. The digestate was applied simultaneously and it was tested if this type of dressing did not influence soil in a negative manner. Results obtained in the Variant 2 (i.e. with the minimum tillage) indicated that, as compared with the conventional ploughing, (Variant 1) values of reduced bulk density were increased and those of soil porosity decreased. However, better values of soil humidity were recorded in Variant 2. In Variant 2, a certain trend to increasing values of Corg/Nt ratio was observed while in Variant 1 values of soil reaction were decreased. It was concluded that these changes could induce soil degradation processes.
