“One of the most important tools a farmer can have as he manages compaction is a tire air pressure gauge,” McDonald said.
In Ohio State University research conducted in a corn crop, a 10-ton axle load showed minimum yield loss under normal soil moisture conditions, however it caused a nearly 10% yield loss in wet conditions. When the axle weight was increased to 20 tons, the results were more dramatic. At 20 tons, under normal soil moisture conditions a 10% yield loss was calculated, and in wet conditions the yield losses increased to as much as 20% from compacted soils.
Equipment weight has increased faster than tire footprint and wetter fields make for tougher access and higher compaction.
ATD’s system reduces axle weights by removing the water.
