How much fertilizer do my crops need?

Profitable crop production — including the efficient use of fertilizer and other best management practices — and environmental protection should go hand in hand. Soil and plant fertility accounts for about one-third or more of total crop yield. On many high yielding or highly managed fields, increased production from fertilizer could be as high as 60 percent.

Lake Erie phosphorus-reduction targets challenging but achievable

ANN ARBOR—Large-scale changes to agricultural practices will be required to meet the goal of reducing levels of algae-promoting phosphorus in Lake Erie by 40 percent, a new University of Michigan-led, multi-institution computer modeling study concludes.

Last month, the U.S. and Canadian governments called for a 40-percent reduction, from 2008 levels, in phosphorus runoff from farms and other sources into Lake Erie. The nutrient feeds an oxygen-depleted “dead zone” in the lake and toxin-producing algal blooms, including a 2014 event that contaminated the drinking water of more than 400,000 people near Toledo for two days.
