2011 Corn Yield by County
Recently the USDA released their 2011 corn yield estimates. This communication serves to not only provide the raw data in the table that is attached, but will allow to visibly compare how each county performed in recent years. The first map highlights the results from the most recent 2011 crop year. The second map shows the current 5-year average (2006-2010). And finally, the third map contrasts how 2011 compared to the previous 5-year average (2006-2010) in terms of percent yield obtained.
These maps, along with the raw data, will hopefully put the 2011 crop year in perspective. It also sheds some light on how your county and surrounding areas have been performing in regards to corn production over time. This data, gleaned from the USDA/NASS web database, allows you to compare your yields to others in your county and across the whole state.
Map 1. 2011 corn yields by county. This map really illustrates all of the challenges that 2011 presented growers in our area. As you can see some counties received timely beneficial rainfall throughout much of the season. Others encountered significant rainfall early reducing root development and increasing denitrification. The lack of measurable rainfall and intense heat after pollination significantly affected final yields the further south you went. Counties in white had no data reported for 2011.
Map 2. 5-year (2006-2010) corn yield average by county. This map shows where the highest yielding corn producing counties have typically been over the last 5 years. Counties in white had insufficient data.
Map 3. Percent yield for 2011 vs. previous 5-year average (2006-2010). Counties with a percentage less than 100% failed to meet their 5-year average yield. Counties above 100% exceeded their 5-year average. Extreme weather variables in 2011 significantly affected yield potential across much of the states. Counties in white had insufficient data.
