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.
Claims29

- and a particulate humic substance based silicon fertilizer, comprising chelates of monosilicic acid-humate compounds.
A combined organomineral NPK—Si-humate fertilizer product according any of the preceding claims, wherein the particulate mineral NPK fertilizer is in the form of a compound fertilizer containing nutrient compounds of N, P and K;
- N and P;
- P and K;
- and/or N and K;
- and/or
- in the form of single nutrient fertilizer containing compounds of N, P and/or K.
A combined organomineral NPK—Si-humate fertilizer product according to any of the preceding claims, wherein the at least one mineral NPK fertilizer is in the form of granules, prills, extrudates, pellets or agglomerates.
