    VISOCOLOR® reagent case for soil analysis
    Reagent case for soil analysis 

    For its many ecological functions a biologically active soil, which is extensively used for agriculture, has to be maintained and supported. The best, economically and ecologically most meaningful procedure is to analyse first the important parameters of the soil before planning measures such as fertilization, liming etc.

    The VISOCOLOR® reagent case for soil analysis has been developed for the rapid, convenient and reliable determination of the soil condition, even in the field.

    Data and ordering information
    REF 914 601
    Type reagent case for soil analysis

    The VISOCOLOR® reagent case for soil analysis contains all reagents, instruments and accessories required for the preparation of soil extracts and the subsequent determination of

    • Phosphate (P)
    • Potassium (K)
    • Ammonium, Nitrite, Nitrate (N)
    • soil structure
    • pH

    The soil extracts are either prepared with Calcium-Acetate- Lactate (CAL) solution (prior to the determination of P and K) or with CaCl2 solution (prior to the determination of N and pH).

    If required by national regulations for soil analysis or because of local geological conditions, the VISOCOLOR® reagent case for soil analysis can also be used together with extraction solutions other than CaCl2 or CAL. Please consult instruction leaflets for possible interferences.

    Reagents are sufficient for 110 CaCl2 extractions, 7 CAL extractions and 60 – 100 tests.

    Shelf life of reagents: at least 18 months

    As refills the following reagents can be used.
