Muck fires result when the loose, organic material found below the top layer of soil ignites and produces a sub-surface fire that can burn for weeks and reach temperatures of more than 500 degrees Fahrenheit. In addition to being difficult to extinguish, muck fires can produce noxious fumes and spread destructive heat to tree roots, causing trees to topple. The heat generated by a muck fire can also transfer underground horizontally to neighboring areas and ignite forest fires yards away from the original subsurface fire.Continue Reading
The organic material that feeds a muck fire, also known as peat, is used as fuel for cooking and heating in many places across the world. Ireland, Finland and Russia use their peat deposits to generate electricity in power plants.
Comprised of decaying subsurface vegetable matter and containing a high concentration of carbon, peat burns with a higher carbon dioxide emission than natural gas or coal. It also burns easily in low moisture conditions and, while still below the surface, can be ignited by a spark from an above-surface fire or through a lightning strike.
Once ignited, smoldering peat fires can burn for weeks or months before they are detected. In the United States, muck fires, as they are commonly called, can occur during periods of drought. They can grow into significant threats to health and property in areas of high peat concentration, such as those found in the subtropical regions of Florida.Learn more about Earth Science
Plant okra when soil temperatures reach 65 to 70 degrees Fahrenheit. Space the seeds about 18 inches apart and 1-inch deep in a location that provides full sun. For a short growing season, consider planting the seed in peat pots three to four weeks before the final frost.Full Answer >
Bermuda grass can be planted when soil temperatures reach 65 degrees Fahrenheit. Bermuda grass can be planted in the autumn, spring or winter if temperatures are high.Full Answer >
To store canna lilies during winter, wait until the foliage dies after a hard freeze, cut the foliage off 2 inches above ground level, use a shovel to dig the clump of rhizomes out of the ground, rinse the excess soil away, and allow the rhizomes to dry in a location with temperatures of 70 to 80 degrees Fahrenheit. After one week, transfer the rhizomes to a cool, dark location with relatively high humidity and good ventilation.Full Answer >
The best time to plant seedling pine trees is late summer or early fall, when soil temperatures are between 60 and 70 degrees Fahrenheit. Exact planting times vary according to local climate, with warmer southern climates requiring a later start.Full Answer >
