update 12-18-2018 – Please note that the following data is not finished. More samples are waiting to be processed, and final quality check is not complete. The basic structure of the data will not change, but the data itself may be updated, added to, or adjusted until we produce the final report.
For statistical analysis, you can find preliminary R scripts here: https://github.com/komland/RFC . These are focused understanding the significance and effect size relating soil quality and food quality, as well as a basic high/low nutrient density prediction model using carrots. Again, these are preliminary, final analysis will be completed soon.
