Water and soil-- two of our most precious commodities. This workshop will discuss how proper landscaping techniques help keep them where they belong-- on your farm or ranch!


When managed poorly, storm water run-off can erode and wash away topsoil, and can pollute our waterways with sediment, chemicals, and nutrients. Our panel of experts will discuss their involvement in creating a win-win outcome developing County of San Diego's watershed protection and composting demonstration site at Ramona's International Equestrian Center.
