Project Timeline

April 2017

Lettuce in outdoor raised beds was harvested on April 19, 2017.

Lettuce transplants will be harvested in two weeks.

February 2017

Lettuce seedlings were transplanted into outdoor raised beds.

Lettuce seedlings are nearly ready to be transplanted.

December 2016

Lettuce transplants were planted in the newly prepared beds and microbial bioproduct is watered in.

Beds were raked in preparation for the next planting.

November 2016

Beds were prepared for harvest on November 15.

October and November 2016

Either low tunnels or low tunnels plus mid-tunnels were used to protect young plants from cold weather.

October 2016 – Seeding at the OARDC in Wooster, Ohio

Step 1. Beds were direct-seeded using ‘Paris Island’ lettuce. Step 2. The beds were rolled to insure adequate seed-soil contact. Step 3. The microbial bioproduct was applied with overhead watering.

Lettuce was direct-seeded using ‘Paris Island’ lettuce in April and covered only with low tunnels due to warm Spring temperatures.

January 2016

Lettuce seedlings were transplanted to the outdoor raised beds at the OARDC in Wooster.

December 2015

Lettuce beds were covered with both low and mid-tunnels. Lettuce was harvested by members of Matt Kleinhenz’s lab.

November 2015

Lettuce was directed-seeded and covered with low tunnels at the OARDC in Wooster. Lettuce was drenched at different frequencies with the microbial brioproduct, BioGenesis ITM beginning with seeding.
