Living Field Lab (LFL)
Initiated in 1993, the LFL is designed to investigate the benefits of leguminous cover crops (as green manure) and the addition of composted dairy manure in two integrated systems compared to conventional and organic systems. The term “integrated” in this case refers to targeted, banded application of herbicide, reduced tillage, and stringent accounting of N inputs using either the pre-sidedress nitrate test (PSNT) or N analysis of composted dairy manure. Since 1993 a crop rotation of corn-corn-soybean-wheat has been compared to continuous corn where every entry point (phase) of the rotation is present every year.
