View Power Point of Plasticulture Cultivars

 

 

Plugs are made from the end of June to 4 July, and planted the first half of August. The field is fertigated with ~12lbs/A of nitrogen (ammonium-nitrate) after one week, every week to 3rd week of September, to a total of ~75 lbs/A. The beds are covered with straw mid-December to mid-March. Frost protection is a combination of misters at 34F and Rainbirds at 32.1F. The field is fertigated with ~5lbs/A of nitrogen per week in April, to between 20-30 lbs/A. Plots are harvested twice weekly from mid-May through mid-June. Rotation is ‘Essex’ rape - strawberry – corn or sudex – soybeans, with rye-vetch winter covers.
