Symptoms of Sick Soil: As Indicated by the Lawn
Bare Patches – it is really serious if nothing will grow
Shallow Root System – anything less than 6 inches.
Compacted Soil – soil probe penetration less than 6 inches.
Puddling – water quickly runs off or pools in low areas rather than soaking into the soil.
Disease Prone – annual outbreaks of diseases either the same disease during the same time period each year or different diseases through the season. Also related to problems with thatch accumulation.
Insect Infestations – like diseases, insect problems are often related to thatch, but can also indicate low availability of secondary nutrients in the soil.
Thatch – dead grass stems, blades, and roots that are not being reduced (decomposed) into organic matter, but accumulating on top of the soil and creating conditions that favor disease and insect problems, as well as restricting moisture from getting into the soil.
Weeds – particularly if there is a wide variety of weed types.
