Soil compaction is a serious and expensive problem. Severely compacted soil is difficult to work and can lead to poor root and plant development. Compaction restricts efficient water management by limiting the ability of plants to take up water and nutrients from the soil. A compacted zone can also make fertilizers and pesticides difficult to utilize. If not absorbed, they can easily wash away. If trapped near the surface, they can concentrate and damage crops.
Soil Compaction Meter is used in testing the hard of soil, too solid soil may prevent the moisture content permeating, reduces the factor of the chemical fertilizer use. Influence plant root system's growth. That will cause the crops' production reduced.
