Lawrence Mayhew is generally recognized as one of the world’s premier experts in humic acids. He is a chemist and one of the founding members of the Humic Products Trade Association (HPTA) a not for profit organization set up by chemists. HPTA builds accepted standards for testing humic acids to protect all consumers. In addition they fight the over the top claims that gave humic substances a bad name and promote the value they provide to a turf soils program. Lawrence answers questions on humic acids and helps us debunk the myths and mysteries of what this powerful substance can do for any turf manager.
