This soil comes out of the Willamette River, all of our soil in this area is from the River. It Is very much a silt clay that runs off the farmers’ fields in the winter. We use this as the base for all of our soils, it is clean and has no weeds. I do not recommend using It for anything but filling holes or adding base to a project. It will not grow plants or grass very well using it just as it is you must amend it with organics. 2000 pounds per yard.
