PAMI developed a cultivator-based high-volume injection system which:
-maximizes the fertilizer value of liquid swine manure;
-reduces odor during application process;
-reduces the potential of nitrate pollution due to over-application;
-provides will distributed nutrients for efficient crop use;
– can handle slurry trash such as straw, hair, and other foreign material;
– can operate in fields with very heavy surfaces and long stubble.
The key element of the system is a hydraulically powered rotary cutting/distribution system designed specially for the distribution manifold. This manifold is fed by a 500 gal / min (2,202 L / min) umbilical or tanker delivery system and is mounted on a Flexi-Coil 820 chisel of 16 openers placed at 12 inch (300 mm) row spacing. The manifold has been tested in laboratory to assure the uniformity of the application and the whole machine was successfully field tested on 210 acres (85 ha) in 10 inch (250 mm) high barly stubble.
