SILT is bringing equity, justice and diversity to Iowa's landscape. SILT President Stuart Valentine, a financial adviser from Fairfield, IA, explains how. SILT Makes Sense. Donate today because it's the only way. "[SILT] lowers that barrier of entry for that new regenerative farmer to get on the land. We want to see Iowa become a model of regenerative agriculture rather than what it is today which you might think of as extractive agriculture."
