Living Field Laboratory

Objective
The Living Field Lab (LFL) Study was initiated in 1993 to extend basic findings from the LTER Main Cropping System Experiment to a more prescriptive setting that could better inform farmers and extension educators. Two integrated systems that include legume cover crops and composted dairy manure are compared to conventional and organic systems

Description
A unique aspect of this rain-fed field crop experiment is the factorial nature allows elucidation of winter cover vs organic vs inorganic inputs
