| Abstract/Contents: | "In an effort to reduce the amount of phosphorus (P) runoff into lakes and rivers, Minnesota became the first state in the U.S. to restrict the application for P fertilizer to turfgrass. Attempts to restrict or ban P fertilizer application to turfgrass were initiated over 20 years ago and were primarily based on soil test surveys showing that 70 to 80% of home lawns in the Twin Cities Metropoliton Area had soil P levels in the very high range (greater than 25 mg kg-1 Bray P). The implication of these surveys was that P runoff potential is higher as soil test P increases. Prior to the recent state legislation, numerous city ordinances were passed that varied in their restrictions on P fertilizer use and led to confusion among lawn care professionals, garden center personnel, state agencies, lake associations, and homeowners. The state legislation preempts local ordinances and has provision for application of P without a soil test during the first year following seeding or sodding, and in subsequent years when soil testing shows a soil P deficiency. In addition, P fertilizer can be used on a golf course under the direction of a person that participated in a certified training program. The legislation had led to an increase in the availability of zero P containing lawn fertilizers ar retail stores and an increased awareness by many homeowners of P impacts on water quality." |
