What is the difference between RICH EARTHtm and Greensand?
Humic acids and Greensand are quite different as soil amendments because they differ significantly in composition. They both provide trace minerals, but they should not be recommended interchangeably solely on the mineral content. The major components of these are quite different. Please see our web site for more information (www.richearth.net) In summary Greensand is a mineral deposit of variouscations in the oxide form (which is considered to be the least available form of most of those nutrients). Also contains high silicon (sand). Use this product for the potassium content and the small amounts of trace minerals. Comparatively, humic acids are the end result of decomposition and a core component of soil organic matter. Primarily humates consist of approximately 70% organic acids that have MANY benefits to the soil. Use this to help increase the availability of micronutrients, mitigate salts in addition to increasing water retention and germination.
