As others said, it is very fertile. I know 2 people who put it around new homes and it wouldn't even grow grass until it set about 2 years to leach out some of the nutrients. Occasionally I'll see where some farmer has just dozed some dirt over an old pond that had silted till it was very shallow. Usually grows the best looking crops in the field. A guy at a local restaurant told me his neighbor sold the silt out of his pond to a farmer for $12.00 a ton to use as fertilizer. Probably work if it was thinly broadcast like they do the turkey manure out of turkey farms around here.
