Objective
The student knows the effects of machinery weight, tire pressure and different tire types on soil compaction risk. The student also knows the effects of soil type and moisture on soil compaction risk. The student is able to determine tire loads and soil compaction risks on different tire loads and tire pressures using “Compaction Calculator” and “Balance Calculator”. The student is able to utilise tire markings, the information on tire manuals on agricultural wheels and Terranimo on comparing tires and planning of soil compaction risk reducement. The student is able to determine the soil compaction risks of a farm’s machinery and can develop a plan to reduce soil compaction risks.
