The utilization of no-till planting on dairy farms in the northeastern US has been slow in gaining popularity.  Since most corn fields on these farm receive manure applications, farmers generally till to incorporate the manure and reduce nitrogen volatilization.  Manure injection provides a means to incorporate applied manure without tillage.  Ammonia emissions were quantified for a four day period in the spring of 2006 immediately after manure application with a disk injection, a spike injection, a direct ground pressure injector, broadcast application, broadcast application followed by tillage incorporation, or with no manure application.   A dynamic chamber method and ammonia was trapped on acidified filter disks.
