Agronomic concerns when managing tight planting/field work windows
Pioneering agronomist Dan Emmert says planting in far southwest Indiana is about 10 to 15 percent complete. A few nice dry days after 0.4 to 3 inches of rain last week in this area allowed some to get in the field and get the job done.
Emmert says there’s still a lot of work to do before some even start planting. The weather forecast appears to remain uncooperative and will provide narrow windows to do this work. Emmert hopes you will keep this in mind when planting corn after applying anhydrous ammonia.
“Ideally we would like to see 7-10 days, or at least 5 days, between this ammonia application and planting just to give it time to dissipate a bit. If we track faster than that, we really increase the risk of the seedlings burning from that ammonia. We can try to mitigate this a bit by consolidating this ammonia deeper in the soil or if we apply lower rates the risk of burning also decreases.
The same goes for your burndown app. Emmert encourages growers to pay close attention to labels. In a year when herbicide supplies are tight, “people may think of making burn recipes that they haven’t done in the past.”
Emmert went on to say, “It’s just a matter of being aware of the plant return restrictions with these products. So, for example, 2,4-D products vary from label to label, but many of them have a 7-day delay between this application and planting the corn. Now, if you opt for Enlist soy, that’s okay. You can go ahead and replant in there, but another one is with different PPOs. If you are combining two group 14 herbicides, often the labels will put a 14-day restriction before you can switch to soybeans.
Another Emmert concern is that farmers enter the field when the soils are unsuitable, leading to compaction. How do you know if your soils are good? Learn more about pioneering agronomist Dan Emmert in the full HAT interview below.
