Landscaping for Watershed Protection - County of San Diego

Water and soil-- two of our most precious commodities. This webinar will discuss how proper landscaping techniques help keep them where they belong-- on your farm or ranch! Offered in partnership with San Diego County Farm Bureau, this is Part 4 of our 4-part Farm & Ranch Composting series.

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. 

This webinar is funded by the County of San Diego and is intended for residents of unincorporated County. Anyone may attend, however, the webinar recording will be available for 2 weeks to unincorporated County residents only.
