Current Projects

  • Study of ridged gardens via phytolith analysis, and humic acid analysis.
  • (Adding new stuff for 2020) Study of intercropping in maize, beans, squash, and sunflowers with various treatments of other plant species and/or cover crops and the cumulative effect on soil quality, plant health, and crop yield. 
  • Domestication of regional (native Iowan) Chenopodium berlandieri. Currently in year #6-7.  
  • Ongoing projects growing 2 maize landraces, study of potential for differentiating maize landraces from archaeological samples via cob phytoliths – is it a high or low resolution issue?
  • Ongoing collection of plant and soil reference materials for phytolith assemblages and humic acid chemistry
