I've been working with David Marquardt from Dirt~n~Turf Consulting, Inc. for a couple seasons and have been able to fine-tune my management programs as a result. Dave has enhanced my knowledge of soil physical and chemical properties, which has allowed to me reduce my overall costs. General turf quality has also been improved because of Dave's input. What I find especially valuable is Dave's commitment to responding to my needs on a timely basis.
