The Cornell Vegetable Program website offers these timely resources:
“As irrigation water is often high in pH and bicarbonate, high tunnel soils generally climb the pH scale without precipitation to leach through the profile,” Jud Reid, Cornell Vegetable Program, told Vegetable Grower News. “The result of is lower nutrient levels in the plant foliage, ultimately decreasing vigor and yield. Manganese (Mn) deficiency is often the first sign of this problem.”
Solutions include measuring and adjusting pH of irrigation water and using sulfur to reduce soil pH prior to planting.
The six-week course runs from March 1 to April 3 under the tutelage of co-instructors:
- Jud Reid, regional vegetable specialist with the CCE Cornell Vegetable Program.
- Crystal Stewart, regional vegetable specialist with the CCE Eastern New York Commercial Horticulture Program.
By the end of the course, you’ll have the knowledge you need to:
- Complete a basic site assessment and know when to bring in experts to discuss site limitations
- Make decisions to improve or maintain their soil health and fertility in the tunnel
- Select an appropriate high tunnel structure for their site, climate, and production needs
- Select and grow appropriate cold and/or warm season crops for the tunnel
- Employ pest control and trouble-shooting strategies for high tunnels
- Decide if high tunnels make economic, environmental, and social sense on the farm
Fee for this course is $250. Sign up a month or more in advance of the start date and receive $25 off. Sign up for three or more courses and received $50 off your total.
From Betsy Lamb, NYS Integrated Pest Management Program:
Save the Dates! We want to be on your calendars for the New Year!
We will be holding a series of short webinars on Greenhouse/High Tunnel Vegetable IPM on Thursdays from 12-1 in February and March. The intent is for each topic to be briefly covered and then followed by discussion:
- Feb 2: Introduction to the project
- Feb 9 and Feb 16: Basics of light, water fertility, media as they relate to pest management
- Feb 23: Vegetable crop production in greenhouses and high tunnels
- Mar 2: Disease management in greenhouses and high tunnels
- Mar 9: Insect management in greenhouses and high tunnels
- Mar 16: Weed management in greenhouses and high tunnels, especially in winter production
- Mar 23: How to write/use an IPM plan
Zoom information for each webinar will be coming soon. All webinars will be recorded in case you can’t attend in person.
During the week of April 24 we will hold a training session in Geneva to follow up on these webinars. More information to follow on that, too.
We will advertise these programs broadly but if you want to be sure to be included in any future emails, please let me know: email@example.com
This high tunnel at Cornell University’s Dilmun Hill Student Farm was built on rails to allow easy movement between two growing areas.
