Welcome to Small and Organic Farming in the Capitol Corridor!


Welcome!  This website is dedicated to providing high quality, scientifically based and unbiased information to support your farming efforts. We work very hard to share resources that have been validated by both farmers and scientists and to make the information detailed and concise, yet useful and digestible.  
The content in this website largely focused on organic, vegetable  production, but much of it is useful for all types of farming. 
UC Cooperative Extension is a partnership between the University of California and the local farmers to strengthen the quality and productivity of agriculture in our area.  We conduct research, develop production guides and host workshops and meetings as needed and requested by the local community.   
Don’t hesitate to reach out to Margaret with any questions about things that you are seeing or doing on your farm.
