Is Your Organic “Compost Tea” Causing a Problem?

A recent article in American Fruit Grower written by Dr. Trevor Suslow – UC Davis, has been showing up in many publications and it certainly caught my eye. As we think about summer; market gardens and farms; vegetable and fruit harvests; farmers markets and roadside stands; we have to consider what might happen with our harvests once they leave the farm. Organic producers are part of the solution to healthy food but not if we are lax in how we treat and handle the food we sell!

Organic vegetable producers face an uphill battle trying to produce a fast growing vegetable crop that demands high soil fertility, especially nitrogen, and most of our natural organic sources are low in nitrogen and that nitrogen is only slowly available. If you have been growing organically for several years you may have built up your soil N reserves through good crop rotations, use of legumes and compost but there are times when we need a biofertilizer and/or a biostimulant. Especially as you near harvest when plant requirements are at their peak it is only natural to see a plant show physical signs of nutrient stress and you know you need to do something!

Fortunately, we do have some tools in organic agriculture that are approved for use in these periods but (back to that article) Dr. Suslow’s interesting article discusses the downside to applying these tools that may surprise you. On farm experimentation with the making of “compost teas” may be the closest example of a potential problem on the small to mid-sized organic vegetable farm. There is a right way and wrong way to make compost tea. In his article he talks about this formulation being a great source of nutrients for bad bacteria and fungi. Foodborne pathogens like salmonella can be introduced into these formulations very easily and then they use the nutrients in the mix to grow to very high populations. When a grower then sprays this “compost tea” on their crop there is a real danger that these pathogens are on the produce.

How do the bad bugs get into “compost teas?” Most of the organic producers I know love to harvest rainwater and then use that rainwater in a variety of ways. One of those ways is making compost tea. Certainly the rainwater has some nitrogen in it from the rainwater and it is usually a lower pH, another benefit to microbes. But, this rainwater off a roof, can have Salmonella, E. coli and Listeria from birds or other wildlife on the roof. In general they won’t grow too much without a food source but adding your compost may be that food source.

Let me stop here and give you a link to the article. His explanation is much better than mine! https://www.growingproduce.com/farm-management/a-wake-up-call-for-growers-on-biostimulants-and-biofertilizers/?e=bob.whitney@ag.tamu.edu&utm_source=omail&utm_medium=newsletter&utm_campaign=afgenews06162021

Is Organics for Everyone?

It only seems natural that the State Extension Organic Specialist would say, “of course organics is for everyone!” There is an ever increasing demand for organic food as seen in grocery reports. My wife likes to buy organic produce because it tastes fresher. I think they pick organic produce less mature so its not as tough and also they do a better job packing it! More and more farms are getting into organic production because there is a very valid reason for this – organic PRICES are really good right now! So, Is Organics for Everyone?

I think there are two parts about “organic” we need to tackle. The first part is the “principles” of organics. In principle, organic food is great, overall tasty, healthy, and is for everyone. I encourage you to try organic food and to voluntarily use organic “ways” or “practices” in your landscape, garden and home. But, organic “practice” takes on a whole other meaning when you move into a commercial farm situation. What is commercial?

USDA National Organic Program (NOP) uses $5,000 as a cutoff. If you have less then $5,000 in gross organic sales you are not required to be certified by a USDA approved certifier. This means that you are following all the practices for organic certification but you are not certified or better said you are self-certified. You probably believe in the organic “principles” and so you follow the organic “practices” and you can label and sell your product as “certified organic.”

If you gross more than $5,000 in sales then you must be certified to sell organic. This means following all the practices outlined in the law and more than likely selling to a buyer who is also certified to handle organic products. In Texas most of our certified organic producers are in the dairy, forage crops, cotton, peanut, or rice category and they sell their commodities to organic buyers. These producers may follow the “principles” of organic production (they are a believer) but for sure they follow all organic “practices” by law and they hope to make money, because organic crops sell for more money!

What about the small to medium sized farmers market/local market vegetable/fruit producer? To be honest most of these folks are generally following the “principles” and most if not all of the “practices” but do not pay to be certified organic. They generally enjoy good prices locally, they know their customers and their customers don’t demand certified organic. Knowing the farm and farmer seems to be more important than knowing that they passed an organic inspection. Because they don’t certify they are not organic in “practice” but are certainly organic in “principle.”

I know this first-hand! My wife and I have a farm – Dry Creek Farm, and we sell locally at area farmers markets, restaurants and occasionally grocery stores. I am not certified organic but follow organic principles. Trying to sell direct to consumer means that I really can’t use either an organic or conventional chemical when I may have someone eating it in a few hours. I try to ensure that my customers trust me and the way to gain trust is just do the right thing!

So, IS ORGANICS FOR EVERYONE? Sure, but the real question is, do growers who follow organic “principles” only, need to be certified? In “practice,” only if you can realize an added value from a verified organic certification certificate!

Where are Texas’ Organic Producers and What Do They Grow

This map below shows each county that has organic producers. This helps you see where we have major organic growing areas and the legend tells you how many are in those areas. The South Plains is a huge organic cotton and peanut area, the Northwest has organic dairies with lots of organic fields and pastures, and the Southeast is home to the US organic rice production. Organic pecans ( personal favorite) are located in the Southwest along with major organic spinach production.

This image (below) may be a little confusing but basically every producer on the map above lists what they plan to produce on their certification application. I took that information and then added up based on fairly common crops. This doesn’t include dairy, beef or poultry but there are not that many even though they make up a large $ amount of organic production. So, there are 360 farmers and of that number 79 list peanuts as a crop. Now, the vegetable one is a little strange because some growers list many vegetable crops and I put them together. Overall, vegetables is a category that needs more producers in Texas!

AgriLife Organic Workshop on YouTube

You know it is pretty sad that as the Texas A&M AgriLife Extension Specialist for Organic Programs I had to get “schooled” about some resources I should have known about!

In the first picture you can see a screenshot of YouTube where Dr. Emi Kimura, Extension Agronomist in Vernon (pictured) has posted the best organic production videos around for Texas organic producers. I have been working my way through them and they are great and useful. Lots and lots of practical advice, put into practice type advice, and I recommend you take a look. Some are long so get ready to watch on one of those rainy days but it will be time well spent.

Here is the link https://www.youtube.com/playlist?list=PLQeRtwVwL1DNmiHH8jsVgOfHgACk0JVzL

If you click on it you will go right to YouTube and then can choose from the list. Let me know you thoughts.

State of Organics in Texas

Did you know that there are estimated to be around 245,000 farms in Texas – that’s a lot, more than any other state.   Of this 245,000 we have around 360 organic farms in Texas or 0.15% – that’s not a lot, especially when you consider there are over 29 million people in Texas.  Just consider this fact, there are 24,719 fast food restaurants in Texas with $25 billion in sales.  Currently we have 398 organic certified entities in Texas buying and selling organic foods and hopefully some of that food is coming from our Texas organic farm families.  

As we look at Texas with its wonderful climate, growing population, abundant resources and outstanding people, Organic Agriculture has only one way to go – UP!

Potential Pesticide Drift on Organic Fields

The Texas Boll Weevil Eradication Foundation (TBWEF) needs your help, and it will be a big help to you!  They want all organic farmers close to any Texas cotton field, to let the TBWEF know where they are located so there are no accidental drifts onto your certified organic fields.  They will GPS locate and mark your fields so that they can protect them.  You can contact TBWEF at 800-687-1212 or email at communications@txbollweevil.org or contact me at bob.whitney@ag.tamu.edu and I will get them your information.
