Hypothesis
Long-term historical and repeated digestate applications would strongly influence the edaphic soil properties, and in turn, affect the soil microbial parameters.
Conclusion
After a decade of repeated applications of different organic wastes or mineral fertilizer, lasting changes were observed in the soil's physicochemical properties and microbial parameters across all treatments.
Supporting Evidence
- The study assessed the cumulative effect of repeated pig slurry digestate applications on soil microbial communities over a decade.
- Changes in soil microbial communities were analyzed through molecular microbial biomass and diversity assessments using high-throughput sequencing.
- Significant differences in microbial community structure were observed among years and treatments.
Takeaway
This study looked at how using pig waste as fertilizer affects tiny living things in the soil over ten years. It found that using this waste can change the soil and the microbes living in it.
Methodology
The study used an in-situ approach to compare the effects of pig slurry digestate and other fertilization treatments on soil microbial communities over a decade, analyzing soil samples through molecular microbial biomass and diversity assessments.
Limitations
Further research is needed to understand the effects on soil microbial communities across different agricultural practices and environmental contexts.
