29 Aug 2018 05:34 AM
The featured chart displays weekly USDA NASS corn crop condition reports. The values plotted are the combined crop acres estimated to be in either Poor or Very Poor condition. The individual charts show each year's time series since 1986, with this year and two recent years highlighted. Of course, 2012 was the major drought year. This year compares favorably for each state plotted except Missouri. Of those plotted, Missouri has seen the most intense drought conditions this year.

Early Corn Silking

11 Jul 2018 05:36 AM
The most recent update from the USDA NASS Crop Statistics show a rapidly maturing corn crop over much of the midwestern US. The map displays the statewide estimates of percentage of the corn crop in silking stage with the bottom labelled number and colors representing the departure from the previous ten year average. This is an important time of year for the development of corn as hot and humid conditions tend to be a negative for yield potential. Some of these areas are also in drought, which is a negative as well.

Weekly Corn Planting Progress

03 May 2018 05:33 AM
The spring planting season in Iowa has been a struggle. The epic cold and snow of April delayed the onset and widespread rains this week will further delay activity. There was a window of about seven days last week into early this week that allowed for some progress to me made. The featured chart looks at USDA NASS reported weekly crop progress reports since 1979 for Iowa. The estimates are updated by the USDA weekly and the chart shows the yearly progress by day of the year with the top panel and the maximum weekly change each year with the bottom panel. The bottom panel casts some doubt on the perception that farmers are getting the corn crop in faster thanks to bigger and faster equipment. While certainly the size and speed of corn planters has increased since 1979, the number of acres planted per planter has dramatically increased as well.

Corn Denting Progress

07 Sep 2017 05:34 AM
The fall harvest season is soon to get in full swing. The corn crop is running somewhat behind this year. The featured chart displays yearly USDA NASS estimates of the percentage of the corn crop that is in 'dented' stage. This is one of the last development stages before harvest. The most recent analysis places 60% of Iowa's crop in this dented status and the 'x's on the plot denote the date during previous years that were at 60% as well. So we are a bit behind of 2016, but in line with the previous two years to that. It is kind of interesting to see how far 2012 sticks out. Of course, 2012 featured a drought and epic warmth, which got the crop quickly to maturity.

26 Jul 2017 05:36 AM
The featured chart displays weekly USDA NASS crop condition reports by state. Each tan line represents the weekly progression of the statewide coverage of corn crop reported to be in either bad or very bad condition. Three years are highlighted for this presentation, which are the years of 2012, 2016 and 2017. For this year, Iowa is shown to be in about as good of shape as any of the others highlighted here. The worst conditions are shown in Indiana, who has seen flooding rains this season.
