Where can I find buyer? How can I let people know I have hemp for sale?

There is now a Buyer/Seller page on the Division of Extension Hemp website. Anyone can go online, fill out this form, and have their buyer or seller information posted within 5 minutes. They could also check the directory page and try contacting retailers or wholesalers directly.

*UW-Madison Division of Extension assumes no responsibility in the transaction of buying or selling the items listed on this web site. All transactions and negotiations are handled directly between buyers and sellers.

I have also seen a company that has a product listing website: Midwest Hemp Supply and Chicago Cannabis Company (not an endorsement, just an example). There may be others out there. An interested grower said they were going to look into selling online with Amazon. I searched and found over 9,000 CBD products on Amazon’s website.


Can I plant industrial hemp if pesticide (i.e. herbicide, fungicide, insecticide) was applied to the field?

It depends on the product and when it was applied. It may be illegal to plant industrial hemp for anywhere from 0-40 months! The label is law and you will need to look up the rotation restriction if there are any for “other crops” since there aren’t any products labeled specifically for hemp. The reason for the restriction is that if industrial hemp is planted too early after pesticide application, it could contain illegal residue in addition to causing possible injury to the crop. Read more about this in the article Herbicide Rotation Restrictions Before Planting Industrial Hemp or watch the 2019 Industrial Hemp Herbicide Carryover Consideration video.

How can you tell if industrial hemp contains pesticide residue?

You can test for herbicide residue concentrates in similar ways that one would test for CBD, THC, other concentrates. However, not all CBD processors or retailers do this as they are not required, its up to the individual processor. There is very little regulation on CBD retailers in general and almost none for testing for toxic chemicals, but reports out of Oregon showed that when random Cannabis samples were tested many were found to have super high levels of pesticide compounds. One of the chapters of my dissertation talked about regulation for herbicide use in Cannabis. They can get that article here (response quoted from Dr. Leah Sandler, Michael Fields Agricultural Institute)


Where can I get my soil tested?


Growers can take their samples to their local extension office for submittal to the UW Soil and Forage Lab in Marshfield. Be sure the sample is labeled Industrial Hemp. Otherwise, they could choose to submit to a private laboratory of their choosing. You can find a partial listing of laboratories here.

What are the fertilizer/nutrient recommendations for industrial hemp?

No research has been conducted on the nutritional needs of hemp grown in Wisconsin in 75 years. In order to develop nutrient application guidelines for hemp, available peer reviewed literature as well as conference abstracts/proceedings/posters, research station reports, and extension bulletins from the United States, Canada, and Europe were reviewed and evaluated by Dr. Carrie Laboski for their applicability to Wisconsin soils and climate. Read her article on Fertility Guidelines for Hemp in Wisconsin for recommendations. The UW Soil and Forage Laboratory is also giving recommendations to those who send in a soil sample for industrial hemp based off of these recommendations developed by Carrie.


Why is pollen drift an issue?

If you are growing for CBD, pollen drift is particularly an issue if neighbors are growing for grain and/or fiber as pollinated plants have a significantly lower CBD content compared with unpollinated plants. You will also want to remove any male plants to minimize pollen production and spread from your own plants.

What can I do to minimize pollen production from my fields?

Remove male plants as soon as they can be identified.

How can I prevent pollen from drifting from neighboring fields onto mine?

Have a conversation with your neighbors within a 10 mile radius of your field and try to find out who is growing what (CBD, grain, fiber) and if possible, use a different field that is the furthest away and provides the most protection, including tree lines, hills, etc. If you cannot do this or don’t know who your neighbors are, you can plant corn around the perimeter of your field as a barrier.

How can I find out who is growing industrial hemp near me?

See question below “How do I find growers, processors, retailers, etc. near me?

Can the Department of Agriculture, Trade and Consumer Protection share contact information for growers near me?

What is the market for hemp? I’ve heard you can make $10,000/ac if you grow hemp for CBD.

It is only worth what someone is willing to pay for it. Establishment costs are very high. One grower said it cost about $10,000 for seed (for 100 acres) in January and that was double what it was the previous month. There is a cost for extracting the CBD and testing for CBD content.

Also take into consideration that there is a 6-7x increase in the number of grower and processor applications this year (2019) which means more competition for processors and buyers, cropping inputs, etc. If growers had an issue last year finding processors and selling what they produced, imagine what it will be like this year with that many more people.

Lastly, growing this crop is not very easy. Last year’s growers cited a lot of issues and that this crop has a narrow margin for error. Growing hemp without a processor and buyer is very risky. If your clientele are risk averse, this would not be a good fit for them, but if they have money they can spare to invest and are OK with the risk involved, that is up to them. They should really find a market for their product first and then grow it, but if I had to guess I’d say most people are going the opposite way about this.

Can growing hemp save my dairy farm?

I am very worried for dairy farmers getting into hemp thinking it will save the farm. It is an expensive and risky venture at this point with it being so new. It is expensive to get into, has a small margin for error for growing the crop, and there is a lot of competition for finding processors and buyers in the area. This is anything but a “sure thing”.

How do I find growers, processors, retailers, etc. near me?

Ask around. Check out the Division of Extension Hemp website’s Directory listing page. County educators can help facilitate this by hosting meetings, which provide an opportunity for them to network with each other. You could also consider providing participants the opportunity to opt into a participant roster that you create and distribute to those in attendance either at the meeting or sometime after. This would allow them to continue networking even after your meeting is over, especially if they didn’t get a chance to talk with someone. If you provide a directory/roster/listing, you may want to consider including language that this is not an endorsement by extension and that they assume risk when contacting someone they don’t know, etc. You can find sample language in the link above for the directory listing page.

Can the Department of Agriculture, Trade and Consumer Protection share grower/processor information with me?

No, under the current hemp statutes, this is illegal. However, growers/processors can share the information themselves. Check out the Directory Listing page on the Division of Extension Hemp website for a partial directory (made up of those who have found the website and opted in).
