Larsen, Schulte & Tyndall

2% Perennial cover


4% Perennial cover

Small targeted changes can have big benefits for water quality


8% Perennial cover

As perennial cover reaches 10%, reductions in erosion and water pollution can exceed 80%


16% Perennial cover

Opportunities for new uses grow as biomass production scales up

32% Perennial cover


Almost half of Iowa’s corn is used for ethanol, replacing it with perennials has many benefits
