In our training seminars, every student gets a bottle of EME. We teach them by making it in class. They also are trained on how to use their bag of five different soil amendments. This encourages students to use them in the project that they have already started. Some students are just starting
out with a new plot. They really appreciate the fertilizers and are encouraged by the results once their plants start to grow. They can see what is succeeding as they learn how each item performs for their soil.
