Plant nutrient concentrate composition
A seed composition comprising a seed and a first component comprising an agriculturally acceptable complex mixture of dissolved organic material characterized by natural organic matter that is partially humified and methods of seed treating. A method comprising contacting a seed with a first component comprising an agriculturally acceptable complex mixture of dissolved organic material characterized by natural organic matter that is partially humified, where the first component enhances at least one of germination, emergence, root development, seedling vigor, seedling growth, mortality resistance, chlorophyll production, cold resistance, water log resistance, and nutrient uptake compared to similar seed not contacted with the first component.
1. 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.
2. The plant nutrient composition of claim 1 , wherein the first component is characterized by comprising a mixture of condensed hydrocarbons, lignins, and tannins and/or condensed tannins, characterized in that at least 10% of the total % of compounds of the composition are tannins and/or condensed tannins.
3. The plant nutrient composition of claim 1 , wherein the first component is characterized by comprising a mixture of condensed hydrocarbons, lignins, and tannins and/or condensed tannins, characterized in that at least 20% of the total % of compounds of the composition are tannins and/or condensed tannins.
