Resumo:
In 2005, the Iowa NRCS and Iowa DNR agreed to create new groupings of soils and revise the recommendations for tree and shrub species for those soil groups in Iowa. There were several reasons for this revision: there were errors in the previous recommendations; there were new soils identified and mapped; and both agencies wanted a user-friendly system for employees and the public to use.
