The ATC Doublecut with Micah Woods

Doug Soldat is a professor in the soil science department at the University of Wisconsin-Madison. We discussed a recent photo he shared showing dramatically increased snow mold where K fertilizer was applied. Or perhaps it was dramatically reduced snow mold where K fertilizer was not applied.

- If you are in the USA and would like to send your topdressing sand for an analysis of K content, you can send to Dr. Soldat at this address:

Dept of Soil Science
Attn: Doug Soldat
1525 Observatory Dr.
Madison, WI  53706-1299

Regarding samples, these have to come from the USA. Soils require an import permit to enter the USA and he doesn't have a permit for samples for this project. US samples only, please.
