Abstract:

No-tillage (NT) is a common soil-conservation management practice with known agricultural advantages and drawbacks. However, its short- and long-term effects on the soil microbiome have not been well established. Here, we compared conventional (CT), minimal (MT) and NT practices in two agricultural fields in the north of Israel over a period of 3 years. Edaphic properties, plant-associated pests, weed species abundance and soil microbial community structure were assessed to examine the effects of tillage. Tillage significantly altered physical and chemical soil properties, and a significant increase in hydrolytic and redox microbial activities was observed in NT soils from both sites. Consistent with this, the microbial community structure of NT samples diverged significantly over time from those of CT samples. Repetitive tillage and even a single tillage event caused significant changes in the relative abundance of microorganisms at taxonomic levels ranging from phylum to OTU. However, no significant difference between treatments was found in microbial community alpha-diversity or crop yield. Conversely, higher levels of weed diversity and some pests number were found in NT samples. Overall, we demonstrate that tillage plays a major role in shaping microbial community structure, and in influencing additional environmental, ecological and agricultural soil parameters. © 2019 Elsevier B.V.

Effects of tillage practices on soil microbiome and agricultural parameters

No-tillage (NT) is a common soil-conservation management practice with known agricultural advantages and drawbacks. However, its short- and long-term effects on the soil microbiome have not been well established.

Edaphic properties, plant-associated pests, weed species abundance and soil microbial community structure were assessed to examine the effects of tillage. Tillage significantly altered physical and chemical soil properties, and a significant increase in hydrolytic and redox microbial activities was observed in NT soils from both sites. Consistent with this, the microbial community structure of NT samples diverged significantly over time from those of CT samples.
