- Drought creates largest-ever natural disaster area
- Crops may never mature
- The impact of the Midwest’s drought has spawned U.S. Department of Agriculture reports and generated announcements such as this: Widespread drought has created the largest ever natural-disaster area. That area encompasses more than 1,000 counties in 26 states.
My generation remembers hearing about the Dirty ’30s from our elders, and now I tell my young colleagues about the Dirty ’80s. Are we heading into another major drought period?
Looking at the updated U.S. Drought Monitor website, drought has its grip on the upper Midwest and is creeping ever closer to us.
North Dakota farmers know that we are on the cusp of some significant weather-related challenges. The impact of the Midwest’s drought has spawned U.S. Department of Agriculture reports and generated announcements such as this: Widespread drought has created the largest ever natural-disaster area. That area encompasses more than 1,000 counties in 26 states.
Combine that with the World Agricultural Supply and Demand Estimates for U.S. feed grain supplies, which projects sharply lower corn production, and producers likely will see feed shortages and already are seeing skyrocketing grain prices.
Drought issues conjure up many concerns, from feed safety to harvest challenges. While most of this region is far better off than the Corn Belt and other drought-stricken regions, we have isolated cases in our backyard, such as land broken out of the Conservation Reserve Program or a forage crop that had no moisture reserves, that never will make a crop.
Agronomists earlier reported that with the early planting, we had the potential for the best corn crop ever. Now, in the middle of July and without rain, crop losses will occur. Moreover, this area sells much of its feed and forage to more concentrated livestock-producing areas. That draw, fueled by drought, likely will cause feed issues for area producers as well.
The logical questions, given the likelihood of high-cost feed and feed shortages in areas surrounding this region, are: “What are the risks of harvesting these feeds?” or “If I receive feed from the drought areas, what should I be testing for?” Because the state already is dealing with water quality issues, my best recommendation is to stay tuned for updates and be proactive. In other words: Don’t guess. Test.
The security of testing the safety of certain feeds allows the users to make best management decisions before problems develop. But when feed is expensive and in short supply, the temptation is to overuse marginal-quality feed.
Because mycotoxins are species specific, we have no rule of thumb about how much you can feed. For some animals, mycotoxins in feed may create reduced gains. For example, lactating dairy animals already are working hard to produce milk. Reducing their intake would cut into milk production and compromise cow health.
Recommendations on feeding feed containing mycotoxins are not the same for all animals. Hogs have little or no tolerance for most mycotoxins, and horses cannot tolerate even low levels of fumonisin, a mycotoxin derived from Fusarium, which are fungi that can produce mycotoxins in cereal grains.
So what should you test for? In the case of corn shipped into our area, that is a difficult question to answer because much of the feed crop isn’t harvested yet. When receiving corn, the worrisome mycotoxins are aflatoxins, especially for dairy producers, because aflatoxins can be transmitted into the milk.
Granted, the interstate transportation of aflatoxin is regulated, but the purchasers of feeds and related byproducts need to be aware of where the feeds came from, when the feed was harvested and whether weather conditions had any impact on the crop.
Aflatoxins are not considered common to corn in the northern states, but cases have been found in South Dakota and Minnesota, and that’s not far away. So be mindful of the origin of your feed shipments. Besides, if we would experience seven to 10 days of 90 to 100 F heat in our area, our corn could become susceptible to aflatoxins, too.
