Fall Frost and September Climate Outlook for 2019

September 2019 has been pleasantly warmer than usual, and our crops need every bit of that warmth to reach maturity before our first frost arrives. Fortunately, temperatures have cooled slightly this week but just to near average for this time of year.

Fall Frost and September Climate Outlook for 2019

This year’s struggles with weather and climate are continuing this fall. Late planting of corn and soybeans in the spring have now combined with near average or cooler than average summertime temperatures. This combination has led to slow crop growth and the need for an extended frost-free season to ensure these crops reach maturity.

May 2019 Climate Outlook: April Showers Bring May Showers?

The precipitation outlook for May does not show much promise of relief from moisture, as wetter than average conditions are slightly more favored than drier conditions. In addition, cooler than average temperatures are more likely for the first half of May and could continue for much of the month.

Planting Into Wet Soils

It is evident that there are high chances of planting into wet soils this spring. This is not a good decision when normal soil conditions appear to be attainable, but this year we may not have a choice.

Floods Continue With a Wet Outlook

As April unfolds, major flooding continues along the Eastern rivers. The James River is at crest in Brown county the first week of April and will slowly recede while maintaining flood level for much of April.

South Dakota Land Use Trends (2012-2017)

Significant education efforts for natural resource conservation have occurred in South Dakota during the last five years. Many stakeholder groups have brought awareness for soil health and water quality to the forefront.

Managing Soil and Soil Fertility After Flooding

During floods, your fields will experience different amounts of erosion, sediment deposition, and crop residue accumulation. To avoid compaction of these soils it is crucial to let soils drain and dry out sufficiently before removing any large debris from fields or working the soil.

Late Plant Crop Insurance Dates

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.

Stored Grains and Flooding

According to the Food and Drug Administration, grain inundated by watercourses is considered adulterated and must be destroyed. The portion of the grain that is not affected by the water can still be salvaged for its use.
