Welcome to Certified International Trading Company, the exclusive distributor of PHS-10 and Nature's Wonder products. PHS-10 is a peat humic substance formulated from highly humified peat and was first developed by professional engineer H.A. Hartung.

PHS-10 has now been tested at many of the world's leading research institutions and universities, and reviewed by the Organic Material Review Institute (OMRI) and approved for organic crop production.

Testing has shown wheat harvest increases of 63%, with increases of total green mass of corn shown to be as high as 209%. Applications to sports turf can result in less fertilizer, less fungicide, and less water, with increased growth and greater recovery from stress.

PHS-10 is now marketed under the trade name of Nature's Wonder in the agricultural, home and sports turf industries, and is still marketed to the water environment industry under its original trade name, PHS-10.
