Current Projects

• Study of ridged gardens via phytolith analysis and humic acid analysis.

• (New) Study of intercropping in maize, beans, squash, and sunflowers with various treatments of native cover crops and locally sourced soil enrichment materials; their effect on soil quality, plant health and crop yield.

• Domestication of regional (native Iowan) Chenopodium berlandieri. Currently in year #7-8.  

• 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?
