Applicant Details

Please briefly tell us why you are applying to be part of the Certified Naturally Grown program: *
We are a new diversified vegetable farm outside of Tucson, Arizona. We believe in growing with organic, regenerative, and natural practices but without the bureaucracy of Organic Certification. We love the peer to peer and grassroots elements of CNG and respect many growers in our area who have earned CNG certification.
Are you currently third party Certified for your produce operation by any other organization (Organic, Biodynamic, etc)? *
Have you ever been certified in the past? *
Have you ever been denied certification? *
How did you hear about Certified Naturally Grown? *
From farmer mentors including Rattlebox Farm and Forever Yong Farm.
How did you learn to farm, and for how long have you been farming for market? What has prepared you to farm successfully according to CNG standards? *
From my college education and working under mentor farmers in Tucson. I have been growing for market for 6 years. I have worked for many farms who are CNG certified and learned from their practices. Implementing these practices at my own farm will be seamless.

Seeds, Transplants and Buffers

How do you select your seeds? CNG standards call for growers to make a good faith effort to locate organically grown seeds by contacting at least 3 major suppliers. *
We select seeds primarily from Johnny's Selected Seeds, and always choose Organic seeds when available in the varieties we are looking for.
Do you purchase or grow using any Genetically Modified seeds? *
Do you use any chemically treated seeds in your operation? *
Do you grow your own transplants? *
Do you purchase potting soil, or do you mix your own on the farm? *
Mix our own
What ingredients does your potting mix contain? If you purchase a mix, please also indicate which product. *
ProMix mycorrhizae, Down to Earth Fertilizer - Bio Live 5-4-2, earthworm castings
Are all of your transplants grown according to CNG standards, without synthetic fertilizers or wetting agents? *

Please describe your buffer. Be as specific as possible. On all sides, how far is it from your crops to the next closest use (road, conventional crop, residential yard)? Be sure to specify what is grown on neighboring land that is in agricultural use. For example: To the north and east, a wooded area of at least 100 yards separates us from the neighbor's corn fields, to the south is a fallow field at least 100 yards deep separating us from the road, and to the west about 60 feet separates our crops from a field where conventional corn and soybeans are grown. *
To the south is a buffer zone with native vegetation at least 300 ft deep separating us from the road, to the north a fallow field of at least 500 ft separates us from the next agricultural field, to the west a private property at least 300 ft deep separates us from the next agricultural field, and to the east we but up to a wooded buffer at least 200 ft deep separating us from the next residential property.
