The Texas Dairy Industry’s Composting Program
Composting turns manure and bedding into a soil amendment, and it is a great topic for a festival or fair booth. Here is how it works in general and what to check before you start.

What is composting on a dairy?
It is the controlled breakdown of manure, bedding and other organic matter by microbes. Done well, composting produces a stable, earthy material that can improve soil. Done badly, it produces smell and runoff.
The program named in the headline belongs to the Texas dairy industry and should be verified with its sponsor. This independent site cannot say what it offers.
Dairy bedding varies. Sand, sawdust, straw and recycled manure solids each compost differently, and sand in particular is hard on equipment and slow to break down. Know what you are working with before planning a pile.
What makes a pile work?
Four things matter most: carbon-rich material such as bedding or straw, nitrogen-rich material such as manure, moisture and air. Piles are turned or aerated so microbes stay active. Producers watch temperature to know whether the process is working.
Specifics differ by climate. A pile near Stephenville faces hot summers and heavy rain events that can wash nutrients away. Site selection and drainage matter. Ask Texas A&M AgriLife Extension for guidance suited to your area.
Finally, be patient. Good compost takes weeks to months depending on the method, and rushing it gives a poor product. Plan your calendar so the pile has time to finish before you need it in the field.
- Balance carbon and nitrogen sources
- Keep moisture even
- Turn or aerate the pile
- Place it away from waterways with good drainage
What rules apply?
Composting operations can fall under state environmental rules depending on size and what is composted. The TCEQ can tell you what applies. If you plan to sell compost, labeling and product rules may apply, so check with the Texas Department of Agriculture.
Keep records of what goes in and where it goes out. Good notes protect you if a question arises.
Neighbors matter here too. A pile that smells or leaches near a property line can cause friction, so locate it thoughtfully and be ready to explain what you are doing. A visit before you start can head off complaints.
How is finished compost used?
Producers spread it on pastures and crop fields, use it for bedding in some systems, or share it with gardeners. Test the compost for nutrients so you can apply it with care. The NRCS offers conservation planning that may include nutrient management.
For gardeners, plain-language resources from eXtension explain how to use compost. For a bigger picture on soil care, see the crop calendar guide.
Compost is not a fertilizer replacement in every case. Nutrient levels vary, and some of the nitrogen is released slowly. Work with an agronomist or Extension agent to decide how it fits your crop plan.
How can a festival or fair booth show this?
Bring a small demonstration: jars showing stages of compost, a thermometer, and a handout that explains the steps. Staff it with a producer who can talk plainly. Kids love hands-on displays and often ask the best questions.
For booth setup and volunteer tips, the fair and rodeo planning guide covers the basics. Put a clear sign on the table that says what is and is not for sale.
At a fair, a short demonstration beats a long speech. Let a child feel the temperature of a warm pile through a probe and watch their face. They will tell their parents about it all the way home.
Health and safety at the pile
Wear gloves, wash hands and keep food away from the pile. Compost can contain dust and microbes that bother people with breathing problems. The CDC offers general guidance on farm health, and this farm safety guide covers basics.
Fires can occur in large, dry piles that overheat. Monitor temperature and keep piles to a manageable size.
More dairy stories
Over at farm.FM they cover manure and farm life with good humor. Try a farm.FM story on manure and gardens. The dairy section and the food stories are good next stops. If a visitor asks where to learn more, point them to the county Extension office, where an agent can explain composting methods for home gardens and farm fields alike.
