Description
The majority manure is spread on the field in a thin layar. This deposition technique leads to problems from runoff, undesirable order and most importantly a serious loss of the nitrogen content of manure because of exposure to the air. To avoid these problems, injection device of manure was tried to develop.
In this paper, the furrow opener and the injection device of manure were made on an experimental basis and their test results were reported.
The furrow opener cut a furrow appoximately 17.3-18.2cm wide and 7.3-10.1cm deep and pushed the soil to both side. The spread of pushed soil was about 6 times as wide as a furrow. The soil which fell back into the furrow behind the shovel was 15-45% of pushed soil in volume.
The injection device of manure is auger uint and easily can arrenge the injection volume of manure by changing the revolution speed of auger shaft. The manure which was tested in auger was bark. Within the limits of this test, this auger unit would be applied with less required torque of auger shaft by using 60℃ in the angle of auger shaft, 100-400rpm in its revolution speed and above 76.5<cm>^^^2 in the area of feed inlet port.
