Seeds and planting stock practice standard. ( 205.204)
(a) The producer must use Certified Naturally Grown or organically produced seeds, annual seedlings, and planting stock: Except, That,(1) Non-CNG or non-organically produced, untreated seeds and planting stock may be used to produce an CNG crop when an equivalent naturally grown variety is not commercially available, Except, That, organically produced or Certified Naturally Grown seed must be used for the production of edible sprouts;(2) Non-CNG or non-organically produced seeds and planting stock that have been treated with a substance included on the National List of synthetic substances allowed for use in organic crop production may be used to produce a CNG crop when an equivalent organically produced, Certified Naturally Grown, or untreated variety is not commercially available;(3) Non-CNG annual seedlings may be used to produce a crop when a temporary variance has been granted in accordance with
205.290(a)(2); (these variances given primarily because of an extreme natural disaster)(4) Non-CNG or non-organically produced planting stock to be used to produce a perennial crop may be sold, labeled, or represented as Certified Naturally Grown only after the planting stock has been maintained under a system of CNG management for a period of no less than 1 year; and(5) Seeds, annual seedlings, and planting stock treated with prohibited substances may be used to produce a Certified Naturally Grown crop when the application of the materials is a requirement of Federal or State phytosanitary regulations.
(b) Genetically engineered seeds and crops are prohibited.
Crop rotation practice standard. ( 205.205)
The producer must implement a crop rotation including but not limited to sod, cover crops, green manure crops, and catch crops that provide the following functions that are applicable to the operation:
(a) Maintain or improve soil organic matter content;

(b) A wild crop must be harvested in a manner that ensures that such harvesting or gathering will not be destructive to the environment and will sustain the growth and production of the wild crop.
Additional CNG Produce Standards
In addition to the standards from the USDA National Organic Program Final Rule listed above, Naturally Grown includes the following requirements.
I. Old Apple Orchards
Land that was planted to an established Apple Orchards prior to 1965 is not eligible for Certified Naturally Grown status without a soil test for heavy metal contamination.
II. For farms that have a mix of Conventional and Certified Naturally Grown field areas
Farmers must ensure acceptable pre-use cleaning of equipment, and properly sized buffer strips to eliminate any chance of chemical contamination between Certified Naturally Grown and Conventionally grown crops. Farmers must show inspectors that facilities and methods exist to keep conventional and Certified Naturally Grown labeled crops separate.
Most importantly and most limiting, we will NOT Certify farmers who grow a mix of the SAME crop conventionally and Certified Naturally Grown in the same year. For example, while a farmer that grows conventional apples, but Certified Naturally Grown vegetables would be okay, a farmer that is growing 50 acres of conventional carrots, and 20 acres of Certified Naturally Grown carrots and the two fields are contiguous would NOT be acceptable and should not apply to be a part of this program. This situation is different than one where a farmer is using CNG methods throughout their operation, but because of the risk of drift from a neighboring conventional operation, they have agreed to keep separate and not market as CNG a portion of their crop closest to the neighboring conventional crop.
Disqualification from the Program
Farmers may have their Certified Naturally Grown status revoked and their names removed from the website if it is determined that the grower is not adhering to the standards listed here-in.
Farmers may also lose their Certified Naturally Grown status if they do not fulfill Certified Naturally Grown’s other program requirements.
