BLOCK 1 (9:00 AM - 10:00 AM)

Controlled-environment agriculture gives us the opportunity to precisely control the growing environment to elicit our desired plant responses including enhancing phytonutrients. The problem is, what exact strategies should we use to enhance phytonutrients? In this session, we will share insights regarding how phytonutrients change with altered environmental conditions. Additionally, we will share some new data on consumer preference and willingness to pay for these enhancements.

Biostimulants are products that can stimulate natural plant processes that increase nutrient uptake, nutrient efficiency, tolerance to environmental stress, and crop quality. Active ingredients in these products may include beneficial microorganisms, seaweed extracts, humic acids, protein hydrolysates, and many other substances. How do you choose from all the available products and how do you incorporate them into your production system? How is the efficacy of biostimulants affected by the greenhouse environment and other inputs? This session will address these questions and share current research results on different biostimulant products for both greenhouse ornamentals and vegetables.

Roots can begin to decay long before being noticed. Soil-loving pathogens may instigate root invasion at any time during the crop’s development and if uncontrolled for too long, the damage is irreversible. A combination of new and established tools are the best defense and will be discussed in this program.
LOCATION: Piscataquog and Merrimack

Timing irrigation applications to optimize plant-available water -- and yet minimize leaching and loss of nutrients from the rootzone is the “holy grail” of irrigation management. Irrigation systems that apply water on a timed schedule typically rely on active (human) management which is labor intensive and usually not very precise. However, recent advances in sensor-based techniques and especially software capabilities now allow us to cost-effectively achieve highly precise water and nutrient applications, based on real-time substrate and environmental measurements. This presentation will cover the basics of how this is achieved, and demonstrate the impacts of better irrigation on crop yield, disease incidence, and nutrient management.
