Abstract
A combined organomineral NPK—Si-humate fertilizer having at least one particulate mineral NPK fertilizer is provided, which has at least one nutrient compound of nitrogen, phosphorous or potassium; and a particulate humic substance based silicon fertilizer, having chelates of monosilicic acid-humate compounds. The application also relates to a method of production of the combined organomineral NPK—Si-humate fertilizer.
Claims25
A combined organomineral NPK—Si-humate fertilizer comprising at least one particulate mineral NPK fertilizer, which comprises at least one nutrient compound of nitrogen, phosphorous or potassium;
- and a particulate humic substance based silicon fertilizer, comprising chelates of monosilicic acid-humate compounds, wherein the ratio of the at least one particulate mineral NPK fertilizer to the particulate humic substance based silicon fertilizer is from 10:90 to 90:10, based on a total dry weight of the at least one nutrient compound of nitrogen, phosphorous or potassium contained in the at least one NPK fertilizer, and the humic substance based silicon fertilizer.
