Description: A combined tillage and liquid manure injection system was developed in an effort to curb contamination of subsurface drainage effluent following liquid manure application. The system is a modification of an existing liquid manure injection system and includes a coulter and cultivator tooth in front of each injector to provide a small amount of tillage prior to manure injection. Previous research showed a trend toward reduction in subsurface drainage effluent contamination with the new system. but the differences were not significant due to the high variability. This paper describes a field experiment to measure the draft and energy inputs for the modified injection system as compared to two different conventional injector designs and two surface spread systems. Results showed that the pretillage equipment on the modified injection system increased injector draft by 28 to 36% over that for the conventional injection system with narrow (50 mm) injectors. However, the draft of the modified injection system was only 66 to 77% of that for 570 mm wide conventional injectors. It was concluded that adding the tillage tools in front of the injector is practical from a draft and energy perspective.
