A few years after we developed the original Medina Soil Activator, our customers suggested we add other ingredients to the old formula. We never gave up the original product, but we did introduce Medina Plus. It's fortified with essential micronutrients and growth hormones from seaweed extract. You still get all of the natural soil building advantages, while extra ingredients make it an excellent foliar feed to care for plants, trees, shrubs and lawns. We also recommend it for transplanting and compost piles. A combination of Medina Soil Activator plus over 40 trace elements, cytokinin (natural growth hormones from seaweed extract), magnesium, iron, zinc, PABA (para-aminobenzoic) acid, riboflavin, thiamin, biotin, nicotinic acid and all essential trace elements. It is ideal for foliar application to fruit trees and vegetables.
