Measurements of soil compaction
With the penetrometer, the soil can quickly be examined for soles and compact soil layers. The most stressed areas can be located, whether it is a general problem, or only a problem in, for example, tramlines. It makes it possible to work with the areas and depths where there are problems. It can easily be checked whether the work succeeded.
Soles and compactions in the soil arise as a result of traffic, processing, rainwater, etc., and will affect both crops and the work with the soil. If there are compact soil layers, the roots will not be able to penetrate deep down, but will instead bend off at the compactions and move across the soil instead. This limits the amount of land used, as no nutrients are obtained in depth.
Water will have difficulty penetrating the soil, and the risk of drainage will be great. If the water does not penetrate into the soil, there will also be a tendency for wet areas to form, which reduces the cultivable area and complicates the work with machines.
The soils microbiology is considerably weakened by compactions in the soil layers, as it will force the air out of the soil and air is needed for a living microbiology.
The penetrometer measurs resistance in PSI by applying an even pressure to the handles and at the same time read the disply. In addition, there is a color scale that clarifies the level of resistance in the ground.
