1. VISOCOLOR reagent case for soil analysis
This portable laboratory contains all reagents, instruments and
accessories required for the preparation of soil extracts and the
subsequent analysis of phosphate (P), potassium (K), ammo-
nium, nitrate, nitrite (N), soil structure and pH.
The complete case has been designed for rapid, convenient and
reliable soil analysis, both in the lab or in the field. In addition to
the variation for colorimetric evalution, the reagent case is also
available with the compact photometer PF-3. Prior to the analy-
sis, the components of the soil sample must be converted into
an aqueous form by extraction with calcium chloride solution or
calcium-acetate-lactate solution. If required by national regula-
tions or geological conditions, the reagents and accessories can
also be used together with extraction solutions other then those
included in the case; in this case please observe dilution fac-
tors. The measurements are carried out either with colorimetric
rapid tests or with easy to use test strips or photometric with the
PF-3. These analytical methods provide a sufficient accuracy for
rapid determination of nutrients in soil. In addition, the soil ex-
tracts can also be analyzed with NANOCOLOR
®
NANOCOLOR reagents and photometers are not supplied in
this reagent case, but can be ordered separately.
