Fertilizer Granulation Additive manufactured by formal suppliers has core characteristics of odorlessness, inertness and high stability. When used under standard production processes and mixing ratios, it will never change the original inherent smell of fertilizer, nor add peculiar or pungent odors to finished products. It does not affect fertilizer odor properties at all. Fertilizer smell is determined by raw materials themselves. For example, nitrogen fertilizers such as urea and ammonium chloride carry a slight ammonia odor. Organic fertilizer and humic acid fertilizer have an earthy smell and fermented humus odor, while most phosphorus and potassium fertilizers are odorless. These original smells are physical and chemical properties of raw materials. Qualified Fertilizer Granulation Additive participates in production merely as a physical auxiliary material and does not change core components and properties of fertilizer.
Fertilizer Granulation Additive works through physical coating, lubrication and dispersion without chemical reactions. Its molecular structure is stable and contains no volatile aromatic agents, pungent solvents or odor additives. It will not volatilize or decompose to produce smell under normal temperature and medium-low temperature during fertilizer production. Neither will it chemically react with nitrogen, phosphorus, potassium, organic matter, medium and trace elements or other core fertilizer raw materials. Therefore, it cannot change the original odor characteristics of fertilizer. Whether producing inorganic compound fertilizer, single-element fertilizer, bio-organic fertilizer or water-soluble fertilizer, finished fertilizer made with matched compliant additive maintains the same odor as fertilizer produced without additive addition and has no abnormal changes.
Abnormal strange smells detected in some fertilizer production cases are results of non-standard production rather than inherent properties of the additive. First, low-grade non-standard additives are adopted. Some low-cost additives are mixed with industrial waste, inferior grease and pungent chemical auxiliary materials. Their inherent sour and fetid smell may cover or replace the original smell of fertilizer. Second, excessive production temperature causes slight decomposition of additives or accelerates volatilization and deterioration of fertilizer raw materials, generating abnormal odor. Third, unbalanced raw material combination. Slight reactions between highly active nitrogen fertilizer and impurities in additives may intensify ammonia odor or create minor strange smells.
In addition, compliant additives can slightly optimize the odor experience of fertilizer. Their moisture locking and moisture-proof performance reduce ammonia volatilization caused by moisture absorption of nitrogen fertilizer and weaken pungent ammonia smell, making fertilizer odor milder. This does not mean the essential smell of fertilizer is altered. Odorless special Fertilizer Granulation Additive is fully applicable to bio-fertilizer, green plant special fertilizer and household gardening fertilizer sensitive to odor. It will not affect fertilizer quality or create odor pollution while guaranteeing granulation effect. Overall, as long as compliant additives are selected and production processes are followed, fertilizer smell remains unchanged for safe manufacturing and application.
