Bio-Dome at Reiman Gardens

May 2014

Imagine the kind of planting you might find in a space station on an intergalactic outpost. The Bio-Dome display in the Hughes Conservatory at Reiman Gardens explores the fascinating world of aquaponics—growing plants in water along with fish. ISU Extension fisheries specialist Allen Pattillo  helped design the exhibit and his research is supported by the Leopold Center. More about his work   More about this exhibit


Field notes from the STRIPS team: Northeast Iowa

December 2013

In October, the STRIPS team visited Adam Rodenberg at the farm property his family manages near Elkader. The Rodenbergs established strips of perennial prairie between their annual crops to create wildlife and pollinator habitat, as well as to prevent erosion and runoff. The STRIPS team is documenting the practical application of this exciting new conservation practice, which in experimental studies has been shown to reduce sediment loss off a field by 95 percent, even when implemented on just 10 percent of the land.


Tour of the Loess Hills

The Leopold Center Advisory Board and staff toured the Loess Hills in June, where the area forester and natural resource technicians work to maintain and improve a diverse array of farmland, pastures, woodlands, prairies and lakes in one of the Midwest's most unique geologic landforms. 


Aquaponics Grows High-Value Crops

January 2013

A Leopold Center special grant project, led by ISU fisheries specialist Dr. Allen Pattillo, is evaluating the potential of aquaponics as a sustainable form of agriculture. Basil and lettuce, grown without soil, benefit from nutrient-rich waste when partnered with seafood production. See project description

High Tunnel Build

May 2012

It takes team work to construct a high tunnel, which can add at least three months to the market season in Iowa. About 30 volunteers helped with this High-Tunnel Build in April at TableTop Farm southeast of Nevada. The owners qualified for a federal grant to cover part of the cost of the tunnel. The Leopold Center supported part of the cost of this event, organized by Practical Farmers of Iowa.


An Early Iowa Spring

April 2012

"No man can heed all of these anniversaries; no man can ignore all of them," Aldo Leopold wrote about the first wildflower bloom of the year. Unusually warm temperatures across the Midwest brought an early spring to Iowa - along with blossoms, tulips, mushrooms, insects and baby animals. Keep up to date on ISU horticulture at www.iowavegetables.blogspot.com. Learn about the USA National Phenology Network or the Aldo Leopold Foundation's Phenology Project.
