Loss of fertilizer nutrients out of row-crop agricultural fields, particularly bioavailable phosphates, is known to be the primary cause of harmful algal blooms (HABs) in Lake Erie. The phosphates cause harmful algae to proliferate, degrading water quality and releasing toxins. Keep the phosphates on agricultural lands, and the problem is solved.
The Iowa State University STRIPS Project has investigated the placement of native tallgrass prairie strips along the borders and at intervals in row-crop fields. These prairie plantings were able to reduce nitrate runoff by 88%, and phosphates by 90%. Similar or equivalent reductions are possible in Ohio watersheds.
To see how this technology might be applied to Ohio watersheds, to virtually eliminate HABs, download this PDF:

Learn from Ohio prairie experts. Everyone invited.
A Friday evening social (21 July) will be held at the High Plains Shelter in the midst of beautiful Miami Whitewater Forest’s nearly 5,000 acres. At 6:30PM we will enjoy a barbeque dinner. We will have an up-close visit from an owl and great conversation until 9PM. From 9 till to we’ll go for a night walk through a mature forest to wrap up the festivities.
On Saturday we will start the day with coffee, tea and a snack, a welcome and introduction to the ecology of Southwest Ohio; then a fascinating presentation by Dr. David Lenz about the Ethnobotany of Ohio Prairie Plants.
Around mid-morning we will car pool 6 miles to Fernald Preserve for a presentation and easy walk to learn about this 1,000 acre restored and created prairie and wetland site. Once a U.S. Department of Energy industrial complex, it is now a bird watching hot spot and important wildlife habitat.
We will return to Miami Whitewater Forest for lunch, followed by a hayride into the prairie. We’ll load into hay wagons or a van for an 8 mile trip though the 500-acre Shaker Trace prairie and wetland complex. We will stop several times for short walks to view blooming beauties and learn more about the botany and innovative management of prairies, told by several experts. Topics will include rare species, controlling invasive plants, burning and a tour of a 40 acre prairie nursery.
