Two crops in one year may sound tempting, and for some crop species is possible, but before doing so, producers should consider possible crops and compare the potential benefits with the drawbacks.
As a challenging 2019 row crop planting season wraps up in South Dakota, many producers are looking to plant cover crops on unplanted acres. One popular cool-season grass cover crop is oats. Most oats in South Dakota are grown as certified varieties, and it is important to be aware of the legal ramifications behind purchasing oat seed for use as a cover crop.
After oats have been harvested, options exist to keep a living root in the soil. This can be done through growing cover crops. In 2018 an on-farm trial was preformed near Salem, South Dakota to observe how cover crops grown after oats would germinate after common herbicides had been applied.
Proper identification of animals helps create an honest record keeping system. With current DNA blood typing procedures animals can be identified through parentage, but when it comes to everyday practices on the farm or ranch a good tattoo can be a huge time saver in the event of a lost ear tag.
Producers across South Dakota are harvesting small grains. These crops provide an excellent window for adding a cover crop into your rotation.
Spring green-up is the time to be watching for black grass bug activity. Large populations of this early-season pest can cause severe damage to pasture (up to 90% forage reduction) and infest the edges of wheat fields.
In last few years, interest in using cover crops has been increasing tremendously among crop and livestock producers in South Dakota. Growing cover crops following small grain is gaining more attention due to feasibility in cover crops species selection and also the time of the year where cover crops receive longer growing and establishing time than following row crops.
Given the widespread wet conditions present this spring, there are many areas in winter wheat fields with both ponding and saturated (or waterlogged) soils. Producers may want to consider soil conditions and evaluate extended weather forecasts when deciding whether or not to retain a winter wheat this spring.
It’s time to begin scouting pasture and wheat for the presence of black grass bugs. Last year, we saw the highest populations in areas of Central and Southwestern South Dakota. If left untreated, black grass bug populations tend to increase year after year.
Crop insurance late plant dates are fast approaching for planting small grains in South Dakota. Late plant dates for corn, soybean, and sunflower are nearing as well. Producers will want to work with their crop insurance agent to explore planting options and reporting of prevent plant areas.
