摘要:
Methods and related systems for conditioning of granular fertilizers post-manufacture to reduce the generation of dust during handling, transport, and storage of the fertilizers, and/or to increase the agricultural benefits of the fertilizer. The method includes introducing a quantity of an aqueous conditioning agent, such as by spraying, to a plurality of fertilizer granules. The aqueous conditioning agent can include one or more beneficial agricultural and/or dedusting additives including one or more acidifying agents, one or more drying agents, one or more herbicides and/or pesticides, one or more chelating agents, one or more biological agents, and combinations thereof.
摘要:
A method for conditioning fertilizer granules for improved dust control, agricultural benefits, or both, the method comprising: providing a plurality of fertilizer granules into a conditioning vessel, the fertilizer granules having a surface temperature of 10°C (50°F) to 121.111°C (250°F); introducing an aqueous conditioning agent comprising water to an outer surface of the plurality of fertilizer granules in the conditioning vessel in an amount of 0.1 wt% to 10 wt% of the total weight of the fertilizer granules, the aqueous conditioning agent being in the form of liquid, steam, or superheated steam; subjecting the plurality of fertilizer granules with the aqueous conditioning agent thereon to a mechanical energy exposure in the form of tumbling or mixing the plurality of fertilizer granules in the conditioning vessel to condition the outer surface of the fertilizer granules; and drying the plurality of fertilizer granules to remove moisture added from the aqueous conditioning agent until a final moisture content of the fertilizer granules is between 0 wt% to 6.5 wt% of the granules.
摘要:
A biological-laden dry fertilizer includes a dry fertilizer granule and a coating inoculated with a biological agent and applied to the dry fertilizer granule. The biological coating is a solution or suspension comprising water or oil and at least one biological agent, or an emulsion of an oil and a solution or suspension comprising water and at least one biological agent. The at least one biological agent is a biological chemical, plant extract, microbial agent, and/or a living organism.
