Patent ID: 8822379

Claim:
A plant nutrient concentrate composition consisting of, in aqueous solution or dried or lyophilized in a form suitable for reconstitution with an aqueous solution, a first component comprising an agriculturally acceptable concentrated complex mixture of dissolved organic material such that the concentration of dissolved organic material is between about 1000 ppm to about 500,000 ppm, the dissolved organic material comprising: condensed hydrocarbons, lignins, and tannins and/or condensed tannins; an oxygen-to-carbon ratio for the dissolved organic matter of greater than about 0.5; a total number of tannin compounds greater than about 200, the tannin compounds having a hydrogen to carbon ratio of about 0.5 to about 1.4, and an aromaticity index of less than about 0.7 as measured by mass spectroscopy; and a mass distribution of about 47-56% lignin compounds, 33-42% tannin compounds, and about 8-11% condensed hydrocarbon as measured by mass spectroscopy.
