Boost Fall Tillering with Ammonium Sulfate
August 10, 2017
- More fall tillers. Research at North Carolina State University recorded 13% higher winter wheat yields as a result of better fall tillering following ammonium sulfate applications.
- Greater yield potential. Those tillers are vital: 80 percent of yield comes from tillers that produce 30 kernels or more per spike, which are formed in late fall and early winter.
- Better roots. Ammonium nitrogen the form in ammonium sulfate also improved root growth and reduced damage from take-all in research at Purdue University.
- Less nitrogen loss. Ammonium nitrogen resists loss from volatilization roughly five to ten times less volatilization loss than urea according to research at the University of Arkansas.
- Immediately-available sulfur. The sulfate form of sulfur is immediately available for root uptake. That's helpful as the crop gets established in the fall, and vital in early spring before soil temperatures warm up enough to allow the mineralization of organic matter the main sulfur pool in soils.
