John Deere has introduced the ExactRate factory-installed option for precise monitoring and controlling liquid fertilizer application during planting. ExactRate gives operators row-by-row section control to help reduce fertilizer costs and the amount of chemicals applied by shutting off application in areas of overlap or non-application.

How does placement of phosphorus (P) in strip-till compare to other tillage systems and application practices? David Mengel, who currently operates a farm in Randolph, Kan., shares and analyzes results of recent research on P application to corn and soybeans in different tillage systems and offers agronomic considerations for how strip-tillers can be more efficient with P applications.
