Herbicide Carryover Concerns for 2024

Herbicides with residual activity have great utility for weed management. However, due to environmental conditions, some herbicides can persist so that the crop grown next year can be injured.

Risks of Early Soybean Planting in South Dakota

Early soybean planting offers potential yield benefits, but it also poses some risks. Learn some expert tips and considerations for early soybean planting this growing season.

Using Data for Better Seed Selection

As harvest wraps up across the region, winter preparation and planning for next year begins. Yield trial results are a key component when making sound seed selection decisions.

How Early Is Too Early to Plant Row Crops?

Although it can be tempting to get a head start with row crops, it is important to be mindful of soil temperatures and the associated risks with planting early.

Delayed Planting Due to Soil Temperatures?

Although it can be tempting to get a head start with row crops, it's important to be mindful of soil temperatures and the risks associated with planting early.

Soil Temperature for Planting Spring Crops

Soil temperature is an important consideration for deciding when to begin planting spring crops. If producers in South Dakota would like a quick reference for soil temperatures in their area, the SD Mesonet network measures soil temperature at several weather stations throughout the state.

Low Temperature Damage to Corn and Soybean

Temperatures are forecast to reach 32°F or lower in large areas of South Dakota for several nights beginning on May 7, 2020. While a relatively low percentage of planted crops are likely to be emerged at this point in time, producers may still want to evaluate individual fields for crop damage.

Soybean Rolling: Yield Effects

Land rolling soybeans has become a common management practice in many areas of South Dakota. The main reason for using a land roller on soybean fields is to push down rocks and level the soil surface for harvest, in theory reducing the amount of rocks and other debris that can potentially damage a combine header.

Late Soybean Planting: Management Considerations

While saturated soil conditions are prevalent in many areas of the state, extended weather outlooks suggest that producers may be able to return to the fields and resume soybean plantings in the near future. Should management practices change due to the late planting season?
