NRCS fact sheets

Conservation System Guides for Pacific Basin Beginning and Limited Resource Farmers and Ranchers. Through consultation with Pac Basin NRCS field and technical staff, five Conservation Systems Guides (CSGs) were chosen with widespread application for underserved farmer/rancher clients in the American Pacific. Based on Field Office Technical Guide (FOTG) information, Jody Smith and Luisa Castro developed five culturally appropriate Flash presentations demonstrating commonly used Pacific Basin CSGs. To reinforce the information delivered within the narrated presentations, they also developed 15 fact sheets to describe the CSG-related conservation practices. An additional introductory erosion control fact sheet is provided. Click on a title to open a PDF of the fact sheet.
