> A sort of average of the 5 elements keeping the soil between 6.5 and > 7.0 will yeild maximum absorpstion of all needed elements. I have the same charts from several courses and agree re: the acidity/alkilinity of the soil. The other big deals are soil composition-clay to sandy which determines how often to add water and temperature. If your temperatures are less than 50F or more than 90F it doesn't matter how great your macro/micro nutrients or what your soil composition is. Your chiles aren't going to do well. Bottom line: Get your soil tested!!! Dave TLCC http://www.tough-love.com
