Soil compaction can become a problem on land farmed intensively with row crops.  Crop symptoms indicating compactions include poor stand and stunted plants showing nutrient deficiency.

Unusual root growth patterns such as shallow roots, poor secondary root growth, or a few enlarged roots are also typical of plants growing in compacted soil.

Soil compaction is often a result of poor surface structure created by working wet soil.  Soils that are poorly drained or low in organic matter are most susceptible to compaction.

Plant symptoms indicating compaction are similar to symptoms caused by soil insects or nematodes.  Like damage caused by soil pests, compaction can occur in isolated spots of fields.

Proper identification of the problem is important.  Insecticides and nematicides will not correct soil compaction problems.
