With much of the U.S. facing conditions similar to those of the 2012 drought, a look back at lessons learned suggests adjusting management plans may help protect strip-till yields and increase resilience.

Land use changes, nutrient depletion, and drought can make plant roots grow deeper into the soil. But scientists question how that growth affects carbon in the soil.

During extreme soil drying, shrinking clay layers trap soil cations such as potassium, which become unavailable for the plant roots to take up.

A team of researchers led by Carnegie Institution for Science's Anna Michalak and Yuntao Zhou has shown that the widespread drought in 2012 was associated with Lake Erie's largest dead zone since the mid-1980s.

As early corn comes to market in July, growers are reminded that timing counts for a lot when it comes to planting corn. That's why Mississippi State University scientists are researching the effects of planting date, plant population and hybrid selection on field corn yields.

The 2014 corn planting season is certainly off to a slow start in Indiana and elsewhere across the Midwest, primarily due to delayed drying and warming of soils. The April 21 USDA-NASS crop report estimated that 1% of Indiana's corn crop had been planted as of April 20, compared to the 5-year average planting progress of 14%.

Changes in the economics of grain production after drought led to record-high farm incomes in 2012 could mean a shift in the demand for and prices of agricultural inputs for the 2014 crop, a Purdue Extension agricultural economist says.
