The USDA Organic Rules require a soil-building crop rotation that controls erosion, maintains or improves soil organic matter content, manages deficient or excess plant nutrients, and provides for crop pest management. Sod, cover crops, green manure crops, catch crops, and various mulches are included in the rotation to perform these functions, which correspond to the purposes for NRCS Conservation Practices such as Conservation Crop Rotation, Cover Crop, Strip Cropping, and Nutrient Management.
Because organic producers do not use synthetic fertilizers and can use only a very limited list of pesticides or fungicides, they depend to a greater degree on crop rotation with its diverse soil biology to manage nutrients, pests, and diseases. On the other hand, exclusion of herbicides (no carry over from year to year) maximizes flexibility in designing crop rotations that enhance biodiversity, improve soil, and perform nutrient and pest-management functions, while also meeting the farmer's particular market needs.
This webinar discusses crop rotation strategies that many types and scales of organic farms can use to meet conservation objectives, market needs, and USDA Organic requirements. Specific strategies used by organic farms in different parts of the United States are given.

This webinar discusses ecologically friendly practices that support organic pest management, including crop rotations, animal rotations, perimeter trap cropping, pheromone use, and other techniques, as well as their impacts on pests and beneficial. It was broadcast July 26, 2012, by NCAT and was funded in part by the USDA Natural Resources Conservation Service. It builds on an earlier webinar, "Pest Management for Organic Production Systems, which also is available on this site. Rex Dufour, an NCAT program specialist, was the presenter for both webinars.

Florida Organic Growers (FOG)lead NRCS staff on short virtual tours of three certified organic operations in Florida and Puerto Rico. Each organic grower touches on the philosophical and practical aspects of growing organic crops in semi tropical and tropical regions -- including their main production challenges and successes. They also discuss the ways they manage their soils, water, crops, wildlife, and other resources. The growers point out the ways they conserve natural resources in their farms while also identifying areas in they need support to increase their resource conservation. The webinar is being presented by NCAT with funding through the NRCS a national conservation innovation grant project.

From a conservation perspective, biodiversity and protection of natural resources are covered in the National Organic Program's (NOP) regulations. Biodiversity conservation is part of the definition of organic farming, and the NOP requires that farmers and ranchers maintain or improve their soil, water, wetlands, woodlands, and wildlife. In addition, seven other NOP regulations relate to biodiversity and natural resource conservation. This webinar explores NRCS Conservation Practice Standards that help operators meet these NOP requirements, including those protecting resources, providing conservation buffers, and supporting wildlife habitat. It includes a discussion of the Live Earth Farm's conservation efforts near Watsonville, California. The webinar was funded by an NRCS conservation innovation grant and broadcast September 27, 2012, by the National Center for Appropriate Technology (NCAT). Participants include Jo Ann Baumgartner, Wild Farm Alliance; Jim Riddle, University of Minnesota Southwest Research and Outreach Center; Tom Broz, Live Earth Farm; and Jeff Schahczenski, NCAT.
