Gumbo (soil)

Gumbo soil is typically defined by the overwhelming presence of very fine particles of clay, but often has small amounts of sand and/or organic material.^[1]

Although gumbo soils are exceptional at water retention, they can be difficult to farm, as precipitation will turn gumbo into a unique muddy mess that is challenging to work using large commercial farming equipment. Avoiding tillage of this type of soil through no-till farming appears strongly correlated with higher yields, as compared to more traditional tilling practices.^[2]
