Muck soils which are very high in organic matter have been attractive to specialty crop growers for many years. The high organic matter content creates a loose medium allowing root penetration to progress much more quickly than in mineral soils. This loose particle structure is also superior in water holding capacity to mineral soils. When drained and preserved properly it is an excellent growing medium for specialty crops such as carrots, lettuces, mint, onions, potatoes, radishes, and sod. One of the limitations is that the organic matter oxidizes when open and exposed to the elements. Of all the crops attracted to muck soils, onions may be the greatest beneficiary. The high sulfur content improves flavor cooking quality and storability.
