Research (Return to top)

Allison's research focuses on understanding the role of organic amendments in sustainable soil management and specificially how the microbes present in organic amendments can suppress crop diseases.

  • The role of seed colonizing microbial communities in the suppression of infection by the oomycete plant pathogen, Pythium spp.
  • The development of Pythium suppressive non-aerated liquid vermicompost extracts
  • The impact of transplant media amendments on rhizosphere microbial communities in organic tomato production

In the field of Adult and Extension Education, Allison has worked to understand the role that cooperative extension educators play in community development and civic engagement using practitioner profiles created from transcribed interviews.
