The Answer is to Imitate Native Range

Diversity in the Cropping System

Diversity Above & Below Ground

Never a Monoculture

2 – Way CombinationsWinter Triticale & Hairy Vetch

Plants Interacting with Mycorrhizal Fungi

►Assists with P uptake from the soil

►Moves P from the non-legume plant to the legume plant

►Moves N from the legume plant to the non-legume plant

Does harvest method affect crop response?

Harvesting Cover Crops

Grazing 2007 91 bu/ac Corn (’08) 1 Herbicide Application Value of additional

nutrients from manure?

Chopping 2007 68 bu/ac Corn (’08) 2 Herbicide Applications Value of nutrients

hauled away?
