Clostridium has been associated with grass sickness in multiple research papers, ( top 4 from a Google search below) some soil types contain much higher levels than others. Clostridium increases in certain conditions (heavy rain, poor drainage, compacted soil, continuous grazing by horses). Not all clostridium species are pathogenic, though soil continuously grazed by horses contains higher levels of known clostridia pathogens.
There are ways to manage soil containing high clostridium and we offer a free consultation after analysis.
It’s worth testing your soil to see how the soil ecosystem controls pathogens and provides nutrients, there is a 20% discount on the test at www.equibiome.org until the end of November, to see a copy of the rep https://www.vetmicrobia.com then Soil Test.
