Abstract

Liquid livestock manure injection equipment was developed based on the design criteria: easy adaptation,
low draught force and suitability for different soil and crop residue conditions. The equipment featured
two sweeps having a flat shape coulter and two shanks, coupled to 2 m wide implement frame. A 350
liters tank full of liquid manure was mounted on the frame during the experiment. The experiment was
conducted with the equipment in sandy loam soil (11.52% clay, 24% silt and 64.48% sand) using convex
sweeps with a forward speed of 3.49 km/h, depths of soil cut (50, 100 and 150 mm) and rake-angle
of 30O. The soil dry bulk density (1.79 Mg/m3), moisture content (25% wb) and soil strength (10.6 kPa)
were also measured during the experiment. The soil disturbance profiles increase significantly with the
depth of soil cut. The draught forces were also significantly increased with injection depth. The specific
draught of the convex sweep was in the range of 2.68 to 9.87 kN per tool.
