The Problem With Wheat Bales

Wheat Field HarvestFor years you have heard me say that there is no “perfect bale,” rather only bales that meet the criteria for construction: tight, uniform in shape, dry, good color, long straw, etc. I have always said that if you had wheat bales easily accessible then go for it and the same was true for rice, rye, barley, and many other bales. Unfortunately, there is a “new” problem with wheat bales and they are more and more becoming useless when it comes to construction (or at least harder to work with). The reason is all in the size of the crop being grown these days.

Short StrawUnlike crops of old, or even crops grown from heritage seeds in different parts of the world, the average crop grown on commercial grade farms in the United States is now very short, intentionally. The crops have been specifically bred to yield shorter and shorter stalks while maintaining the grain output. This makes sense in terms of minimizing waste (the straw) for the farmer, but it means that the bales that we see on the market these days are full of tiny scraps of straw that don’t hold together well during construction.

Ideally, you would be able to find a source for long straw bales in your area. This means straw stalks that are roughly 2′ long or longer within the bale. In order for this to be possible, your farmer would need to be growing from heritage seeds, not the more modern, “domesticated” crops, and they would need to harvest with a low-cut sickle mower rather than a rotary combine harvester. This really narrows down the source to a few, small-scale farmers in most areas. If you can’t find that farmer, then be sure to find the bales containing the longest straw within them that you can find in your area. The impact of the longer straw is worth the effort of searching as your walls will be tighter, easier to get straight, more energy efficient, and stronger over all.

    Could we also facing problems with genetic modification and the use of herbicides and pesticides, that is sprayed on the wheat during it’s growth, Therefor bringing toxins into the home.

    Thanks for the information. I thought I noticed that wheat seemed shorter than I remembered as a child. I thought it was because I had grown, but you cleared that up substantially.

    The pesticides can certainly be an issue. I have not seen any research on what residue is left over after the straw is baled, but I imagine there is a chance it would be contaminated. That said, once plastered, I don’t see it being an issue as the walls are sealed tightly against any movement of solids like pesticide residue.

    What is the best type of bale to use? How is flax straw? Or maybe oat straw?

    I have not used flax straw, personally. I can say that any straw that is local to you that fits the details of dry, uniform in shape, LONG individual stalks within the bale, tight, and free of water damage is a good option. It’s more about the quality of the bale than the type of grain it comes from.

    We are looking to buy straw bales for our house soon and we have two offers on the table. The first offer is very local (within 5 miles) with tight metal wire, wheat straw bales. The bales look good in all ways except that the straw we pulled out was in the 4-6″ range. The second offer is from 30 miles away, it is oat straw with tight poly twine, and 12-14″ stalks. These bales look good as well. Price is the same. Which would you go with? Exactly what issues do you run into with shorter stalks? Does it make re-tying bales a lot more difficult?

    Without question I would go with the oat bales. Longer stalks make notching, retying, and over all wall strength better and make stuffing the window and door shapes as well as plastering easier too. Further, wire ties are a pain to work with and are dangerous when hit with a chainsaw by accident. Happy baling!
