Based on its use are distinguished:

    Foliar fertilizer means a fertilizer is fertilizer dissolved in water and sprayed on the leaf surface.
    Aksr fertilizer or soil fertilizer is fertilizer applied to the soil around the roots to be absorbed by plant roots.

Based on physiological reactions are distinguished:

    Fertilizers have a physiological reaction to sour it mean when the fertilizer is given to the soil there is a tendency to become more acidic soil (pH becomes lower). For example, Za and urea.
    Fertilizers have a physiological reaction is the basis of fertilizer when applied to the soil causes the soil pH tends to rise eg fertilizer chili Salpeter, calnitro, calcium cyanide.


Based on the amount of nutrients they contain are distinguished:

    Fertilizers that contain only one nutrient plant. For example: urea containing only N, P TSP just overlooked it (actually containing Ca).
    Compound fertilizer is the fertilizer which contains two or more two plant nutrients. For example: NPK, amophoska, Nitrophoska and Rustika.

Based on the variety of plant nutrients are distinguished:

    Fertilizer is fertilizer containing macro macro only just: NPK, nitrophoska, Gandasil.
    Micro fertilizer is a fertilizer containing micronutrients only just for example: mikrovet, mikroplet, metallic.
    Mixture of macro and micro fertilizers Gandasil example, bayfolan, Rustika. Often mixed into macro and micro fertilizers also added plant growth regulators (growth hormone).
