The 2015 Iowa Cover Crops Conference will be held in West Des Moines on February 17 and 18.
The annual event is hosted by the Soil and Water Conservation Society, Conservation Districts of Iowa , and the Midwest Cover Crops Council. This year’s event will include a presentation from Iowa Secretary of Agriculture Bill Northey as well as farmers and other agribusiness professionals.
Cover crop usage in Iowa has gained momentum in recent years with just 10,000 acres planted in 2009 and more than 300,000 acres by 2013. Cover crops are one of the techniques outlined in the Iowa Nutrient Reduction Strategy as a way of minimizing fertilizer runoff which pollutes waterways. Approximately 70 percent of the nitrogen and phosphorus in the Gulf of Mexico dead zone came from the Mississippi River.
A report by the international consulting firm Datu Research last year found that 23 percent of Iowa farmers reported utilizing cover crops. The report found that Iowa farmers are also practicing no-till and minimum tillage techniques as well as crop rotation, all of which can reduce runoff and improve soil health.
An ongoing study by researchers at the University of Illinois suggests that the use of cover crops does not increase yields but it does “increase the amount of sequestered soil organic carbon.” However, research by scientists at Purdue University has found that cover crops can improve corn stover yields which can be used as a biofuel.
The cost of next month’s event is $99 for those who register before February 16 and $125 for those who register onsite.
