Southern New England Vegetable Growers Meeting Series

Greenhouse Seedling Production: compost-based potting mix, nutrient management, chlorination, and tray selection

Adequate nutrient levels in substrates are achieved by providing the right amount and type of the fertilizers and maintaining an optimum pH. Rosa Raudales will discuss how to: use water quality to develop nutrient programs with conventional fertilizers, safely and effectively inject chlorine in irrigation systems, and choose the plug-trays sizes for seedling. Additionally, there are many commercially available compost-based mixes on the market, and many growers also create their own. Sometimes they work better than others (both commercial and farm-made). Why? Andy Radin will discuss factors to consider if you use these types of mixes.
