Question:"A caller from the local Community College asked why a 3- to 4-ft area in one of the tall fescue lawns was dying. He said it looked like it was caused by lack of water, yet the soil was moist and had been irrigated just like the surrounding tall fescue turf."
Answer/Response:"An on-site visit with a soil probe showed a 'grayish' color to the soil about a foot under the dead spot. Soil from surrounding healthy turf looked normally 'dark brown' in color. Both areas had adequate soil moisture, but were not saturated. Sniffing the cores revealed the likely cause as natural gas in the soil. The gray cores had a distinctly musty smell; almost sulfur-like, which is usually indicative of a lack of oxygen. The gas replaced all the oxygen in the soil, leaving it anaerobic. The Gas Company was alerted and responded quickly confirming that a line was leaking and repaired the pipe. By leaving the hole open for a period of days the gas dissipated from the soil pore spaces, so a successful replanting of the lawn could take place."
