It has been two years since my soil sampling occurred. It was a major undertaking with wet, rainy conditions that required three days of sampling at different time points over 6 months. Today marks the anniversary of the first day of sampling. The final day of sampling occurred in September of 2016.

These soil samples have undergone chemical, physical, and biological analyses. I’m still working on the biological analysis to characterize antibiotic resistance genes. But I’ve already quantified antibiotics in these soils and will have a publication with some of that data coming out fairly soon. It’s hard work, but definitely worth it!

Enjoy some pictures from soil sampling where we had to plow down some corn.

Showing where the soil core starts (top of it) and you can see our hydraulic soil sampler behind me that allows us to take soil cores down to 80 cm or more.

Complete soil core!

Putting the endcaps on a soil core.

Fallen tree that thankfully did not impact our sampling, but meant we had to go around it.

Very wet conditions…a small stream in the field.
