August 2019 Climate Outlook: Cool and Wet

According to the latest climate outlook update, odds are favoring that August 2019 will be cooler than average. The update was released by NOAA’s Climate Prediction Center on July 31, 2019.

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.

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.

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.

Winter Survival and Spring Stand Counts in Winter Wheat

Every winter, growers are curious if their wheat field will survive the winter. Not enough snow cover during the coldest days, spring flooding, and ice injury are the main reasons for plants to die. The only way to get a true assessment of winter survival is to scout the field in the spring.

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.

Standing Corn Considerations

The January 2020 South Dakota Crop Progress Report indicated four percent of S.D. corn acres remain in the field. Given the record rainfall of 2019, current snow pack levels and the 3-to-6-month precipitation forecasts, farmers will likely be dealing with a wet spring in 2020, thus making the removal of those acres important but hard to accomplish.
