Abstract

Soil compaction due to traffic of agricultural machinery and tillage implements that affect soil physical properties and agricultural yeilds is accentuated with increasing mechanization of agriculture using higher power tractors. Compaction of soil under tractor tires has been studied by many researchers, but reports on soil compaction due to tillage implements are few.In this investigation, soil compaction caused by plow bottoms is studied. The effect of parameters such as forward speed, soil moisture contect and texture, and type of tillage implement on soil compaction at bottom of the furrow and the layer 4 cm below it was invesigated.A Complete randomized block design was used and soil bulk density was measured as index of compaction.Results of statistical analysis indicated that bulk density increased significantly with soil moisture content. Both soil and implement types significantly affected soil compaction of the). furrow bottom (and at constant moisture content Mean compaction at the highest moisture level lowest speed for the moldboard plow was 14.18%.Increasing forward speed resulted in decreasing compaction. Soil moisture being constant, compaction for the soil with lighter texture at equal velocity was lower for disk plow than moldboard plow. This compaction at 18.25%moisture content in the silty-Ioam soil was 5.3% . In all treatments no significant compaction was observed in the soil layer below the furrow bottom.Although weight of moldboard plow was lower than that of the disk plow, because of the nature of soil loading by moldboard plow bottoms, they caused more compaction than the disk plow bottoms.
