<p>A method of improving agricultural and horticultural crop yields utilizing a mixture comprising a water-soluble alkali metal salt of humic acid and a plant nutrient component including plant nutrients such as nitrogen and/or phosphorus and/or potassium and/or either calcium phosphate or ascorbic acid. The addition of a liquid mixture comprising the plant nutrient component and a water-soluble alkali metal salt of humic acid to the growth medium or seed germination medium of agricultural or horticultural crops has demonstrated improved crop yields both in the size of the individual fruit and in the number of the fruit per plant.</p> |
