Gumbo (soil)
Gumbo soil is a mixture which often has some small amounts of sand and/or organic material, but is typically defined by the overwhelming presence of very fine particles of clay [1]
Although gumbo soils are exceptional at water retention, they can be difficult to farm, as precipitation will turn gumbo into a unique muddy fiasco that is challenging to work using large commercial farming equipment. Avoiding tillage of this type of soil, thru "no-till" farming, appears strongly correlated to higher yields versus more traditional tilling practices.[2]
