Farmland Management and Practices

Primary Tillage System: *
We have not tilled the vineyard at all in many years.
Do you use Cover Crops? *
If yes, please list: *
We no longer seed a cover crop, but allow the naturally growing mustard, grasses, wild oats, legumes and vetch to grow tall between the vine rows before mowing in the spring.
Do you use Compost? *
Do you use Manure? *
Please list any other brought in fertility sources that you use (specific rock powders, lime, soybean / alfalfa meal, specific purchased pre-mixes, etc)and how often it's used. If you indicate a name brand product, please also specify the ingredient/s. *
Fish emulsion, kelp (in foliar sprays)
Have any chemical fertilizers been applied to the fields you are seeking Certification for in the last three years (36 months)? *
Have any non-acceptable pesticides and/or herbicides been applied to these fields in the last 3 years? *
If yes, then please specify type and most recent application date: *
Our last application of Roundup herbicide was January 2018 And the last use of Rally (nonorganic fungicide) was August 2018 Since then we have made a commitment to no longer use ANY non organic materials
Do you use Professional Soil Testing services? *
Describe your primary weed problems AND methods of control. Do not answer "none". You MUST indicate either actual weed challenges and/or LIKELY challenges, and you must ALSO indicate how you manage (or would manage) them. If you indicate a product, also specify how often it's used. *
Weeds that grow under the vinerow cause problems by creating a habitat for voles that can girdle the vines, and get in the way of harvesting the grapes. We used to apply Roundup in a strip spray to manage these weeds, but after my father developed cancer we have made a renewed commitment as a family to create a healthy environment for this property, our hone, and every living Living organism on it. We have been experimenting with various undervine weed controls now, such as “weedslayer” (an organic herbicide that uses clove oil), undervine tractor mowers and weed whackers. The herbicide we sprayed undervine twice in the spring in January and May.
Describe your primary insect challenges AND methods of control. Do not answer "none". You MUST indicate either actual pest challenges and/or LIKELY challenges, and you must ALSO indicate how you manage (or would manage) them. If you indicate a product, also specify how often it's used. *
We spray sulphur at least once a year to control mite populations. By not tilling the soil, the lack of dust also helps keep mites at bay. We encourage a healthy natural ecosystem here, with many bird boxes, owl boxes and bat boxes. The biodiversity keeps all pests in natural balance.
Describe your primary disease challenges AND methods of control. Do not answer "none". You MUST indicate either actual disease challenges and/or LIKELY challenges, and you must ALSO indicate how you manage (or would manage) them. If you indicate a product, also specify how often it's used. *
Our primary issues in the vineyard are botrytis and powdery mildew. Canopy management to encourage airflow is our primary tool. We pull leaves around the fruiting zones on the northern side of every row to create a dry environment and dappled sunlight effect. We also keep our spray intervals short, around every 10-12 days between budbreak (or shortly thereafter depending on soil wetness for the tractor) to veraison when we stop spraying. We alternate between spraying sulphur, Stylet oil (mineral oil, organic) and Sonata (organic yeast byproduct)
Please list the water source you use for crop irrigation. If source is public river, pond or lake, please note the name: *
Natural artisan springs fed to a holding tank on property. We have very little water available, and thus irrigate very little or in some areas not at all.
Are there any known contaminants in the irrigation water? *
Are you a maple producer who seeks to certify your sugarbush? *

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. *
Whenever we need to buy seeds for cover cropping or in our personal garden on site, we buy organic seeds from Leballisters, a local seed supplier.
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 any transplants from outside sources? *
Chemical/Spray Drift and Buffers:
Is there any likelihood of Chemical/Spray drift contamination of your fields? *
Do you have an adequate buffer to protect yourself from potential contamination? *
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. *
We are located in rural Sonoma Mountain, with plenty of space between neighbors and only one nearby farm. To the East and South there are many acres of wooded wildlife corridors. To the West is a neighboring vineyard, 100 yards from us. They farm organically, but we still maintain a natural buffer of oak trees, elderberry and bay. To the north is a rural road with a Buddhist retreat center about 100 yards beyond. We maintain a buffer of oak and cedar trees between the vineyard and road.


Please indicate your agreement with the following statements by checking the boxes.
I will not label, or in any way lead consumers to believe that produce not raised in accord with CNG standards is Certified Naturally GrownTM. *
I understand that I have to complete at least one (and hopefully more) Certification Inspection(s) of another farm in my area each year, and that the inspection will NOT be of the same farmer that inspected me. *
I have reviewed the Certified Naturally Grown certification standards, I understand them, and I will abide by them. I understand that if I have any questions I may contact CNG for clarification. *
You may use this space to tell us anything else you think we should know about your farm:
My brother and I have been fighting to improve the health and vitality of this farm for years, following our father’s use of some conventional chemicals in the past. We both live on the vineyard property, along with our employees and all of our families. We work here every day, grow our food here, drink the same spring water that goes to the vineyard. I plan to raise my children here, running through the grapevines. We are passionate about a lifelong commitment to farming organically and leaving this farm healthier and improved day after day. I know it is a constant process of learning and I hope to one day be able to afford the organic certification process. But as we are in transition I believe becoming certified naturally grown would help us show our commitment to our buyers and aid us on our journey.
