2019 Corn Growing Degree Day Update

Growth and development in crops are a direct response to accumulated heat units or growing degree days (GDD). The Corn GDD Tool at the High Plains Regional Climate Center can be a useful resource for not only estimating crop growth stage, but also for selecting hybrids within the appropriate maturity group.

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.

2019 South Dakota Grasshopper Forecast

The USDA Animal Plant Health Inspection Service conducts an annual survey to monitor grasshopper populations in Western South Dakota. In 2018, SDSU conducted a survey to monitor populations in Eastern South Dakota. These previous-year surveys can be used as a prediction tool for where grasshoppers may be an issue during the upcoming season.

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.

Why Precision Agriculture?

When precision agriculture comes into a conversation a few questions arise. Three of those questions might be: What is precision agriculture? How does precision agriculture make our farm more profitable? What do I do with all this data?

Seeing Dead Soybean Plants in a Circular Pattern? Could Be Due to Lightning

While quite uncommon for lightning to damage row crops, it does happen. Thunderstorms can have lightning that can burn soybeans plants leading to their death.

Drought Stress Symptoms in Soybean

Soybeans in South Dakota are in their moisture-critical reproductive stage. Drought stress during this growth stage can significantly impact yield, so here are some things to look for.
