Two management directives led us to a bio-extensive design. First, because our staff is small, we required a system that would provide inherently good weed control. Bermuda grass was a particular concern. Our second directive demanded a reduced dependence on outside fertility inputs, particularly industrial poultry litter. Many, if not most, of the organic market farms in our region depend on broiler or layer litter for annual supplies of nitrogen and organic matter. We wanted an alternative that would be more independent and sustainable.
