Month: April 2024

As of April 11, 2024, the Nebraska Drought Monitor shows 55% of Nebraska in moderate to exceptional drought (D1-D4), compared to 98% a year ago. Planting is critical for everything else that happens during the growing season. This article shares our UNL planting considerations and provides additional considerations when planting in dry conditions.

Agronomic Considerations

Soil Conditions
This is perhaps the most critical component to planting because soil conditions set the stage for the decisions we make regarding planter adjustments, which crop is planted, and planting depth. Some areas of the state received some fall/winter/spring precipitation to help with replenishing soil moisture, while other areas continue to have a lack of subsoil moisture due to a lack of precipitation events. When planting into drier conditions, increased down pressure is most likely necessary; however, be careful of causing any sidewall compaction.

Soil Moisture, Temperature and Planting Depth
Corn needs to absorb 35% of its weight in moisture to complete the imbibition (water uptake) phase of germination. When adequate soil moisture is available, this typically occurs within 48 hours. Soybean needs to absorb 50% of its weight in moisture to complete the imbibition process. When adequate soil moisture is available, recent research has shown imbibition can occur anywhere from eight to 24 hours. Once imbibition has occurred, soybean seeds enter an osmotic phase and are quite tolerant of soil temps as low as 35-40°F, although extended low soil temperatures can be expected to lengthen the germination to the emergence timeframe.

In general, we’d recommend planting…
