Spots of excitement—snow mold spots—in an otherwise boring potassium experiment, with Doug Soldat
The ATC Doublecut with Micah Woods - Podcast tekijän mukaan Asian Turfgrass Center

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.- See the photo we discussed: https://www.asianturfgrass.com/post/k-fertilizer-and-more-snow-mold/- Watch this episode at https://youtu.be/ilPhk30NQlQ- Bier et al. article on K supply from topdressing sand: A long term evaluation of differential potassium fertilization of a creeping bentgrass putting green, https://doi.org/10.1007/s11104-018-3765-8- 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 ScienceAttn: Doug Soldat1525 Observatory Dr.Madison, WI 53706-1299Regarding samples, these have to come from the USA.
