Crop Rotation Affects Disease Suppressive Soil Microbiomeslog

Crop Rotation Affects Disease Suppressive Soil Microbiomes

  • Start date: 2021
  • Project Length: 2 Years
  • Project Status: In Progress


Benefits to MB Producers: Plant and soil host highly diverse microorganisms, which provide accessory genome and reservoir of essential functions to economically viable plant traits. Now the agricultural community demands more sustainable production systems; as a result, many chemicals (e.g. pesticides and fertilizers) will be taken out from the market due to its enormous negative impact on environments. Withdrawal or reduced pesticide applications may have an immediate effect on pest management and eventually yields in the intensive crop production system.

  • Objective: This study will identify several patterns of the microbial community structure (abundance, diversity and composition) that gives a variable success of disease suppression; provide measurable evidence toward which crop rotational plot(s) have relatively more bio-control microbial taxa (e.g., bacteria) and less abundance of pathogenic taxa (e.g., fungi) and dentify suitable crop rotation for prairie crop growers in which pathogenic soil microbes are suppressed, and biocontrol microbes are enhanced and activated over cropping seasons.
