WQFS Plot Management
The 48 drainage lysimeter plots are divided up into 4 replications of the cropping systems listed. Click here for a more detailed listing and layout of the treatments and replications.
The tile spacing plots are planted under continuous corn with starter N and P and 160 pounds preplant N.
Tillage operations consist of fall chisel-plow on corn plots and then spring disk and field cultivated. Soybean plots are spring disked and field cultivated. Herbicides are used to keep down the weeds during the growing season and no cultivation occurs after crops are put in the ground.
