Given the longer season and higher yields of tunnel tomatoes, a nitrogen fertilizer to inject or side-dress will help prevent mid-season deficiencies.
Our recommendations and pre-plant and in-season organic nitrogen sources are provided in the PDF below.
This work is part of a 2-year project between CCE Cornell Vegetable Program and NOFA-NY with support from the New York Farm Viability Institute.

Upcoming Events
Niagara Region Vegetable Meeting

August 14, 2024
Clarence Center, NY
We'll start this meeting off at Root Down Farm to hear late season disease management updates in peppers and cole crops, plus current best management practices to limit fungicide resistance. Potato variety recommendations and disease control questions in potatoes will be addressed.
Then we'll head to Kreher's beet field to view and discuss alternative weed control technologies. The beet field is an on-farm demonstration of various flame weeding protocols in comparison with stacked tool cultivation equipment. One or two weeding robots will be on-hand for live demonstrations and discussion of the technology's current abilities and future potential. We'll also cover industry updates and a review of late summer disease management in squash.
2.0 DEC credits will be available in categories 23, 1a, and 10.
