dc.description.abstractDuring 1979 and 1980, soil fertility research was conducted at two locations in the Delta Clearwater area. One of the test sites, Lee F ett’s Farm, was cleared in the mid-1950s and has been in production for about 25 years. The other test site is situated on a tract of newly cleared land owned by Dennis Green. The new lands site was cleared by the traditional berm-pile method during the winter of 1978-79. This method removes much of the moss layer, and in some cases, part o f the topsoil. Land cleared by this procedure is lower in natural fertility, but has the advantage of enabling the farmer to plant a crop the first summer after clearing. In this publication, progress reports are given for several research projects involving fertilizer use and rates of application.en_US
