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 C org /N t ratio was observed while in Variant 1 values of soil reaction were decreased. It was concluded that these changes could induce soil degradation processes.

An Overview of the Control of Bacterial Pathogens in Cattle Manure

“…In addition, water sources, both surface and underground are greatly protected from pollution due to treatment of the raw manure within a confinement where it becomes stabilized and sanitized [ 137 ]. Moreover, the stabilized material (digested slurry) with high nutritive value can be applied to soil as a conditioner/fertilizer to protect the land from erosion and depletion [ 138 ].…”

“…Consequently, they play critical roles in many biological processes necessary to maintain the fertility and quality of the soil [ 123 ]. However, when the soil environment is compromised either via sterilization or excessive use of chemical fertilizers; the enteropathogens introduced by way of amending the soil with inadequately managed compost/digestate will survive for a period of time depending on the specific bacteria since they will be nourished by the inherent soil properties (nutrients, water and oxygen) and the microbial community diversity must have been reduced [ 138 ]. Therefore, combating the likelihood of antagonism, competition and predation in the environment.…”
