All cuvettes are labelled with a barcode which provides all necessary information for the photometer. When inserting the cuvette in the photometer, the integrated barcode reader recognises the cuvette and the required wavelength and factors are adjusted automatically. The rotation of the cuvette during the measuring process makes operating errors and incorrect measurements virtually impossible. The evaluation of the measuring results can be carried out in
- mg / 100 g soil for soil analyses
- mg / liter substrate for substrate, peat analyses
- mg / liter solution for nutritive solutions, drainage water, etc.
The interpretation of the analysis results are carried out according to users requirements. Tables for different plants are provided particularly for the corresponding application.
An important component of the LASA AGRO system is the interpretation of the measured values. The evaluation using tables is a simple way based on the long-term experience of the official German Agricultural Investigation and Research Institutions (VDLUFA). For both horticultural and agricultural outdoor crops, the tabular guide values are given in mg / 100 g soil nutrient, either as pure nutrient (e.g. with N, Mg) or in the oxide form, e.g. K2O or P2O5. A conversion is no longer necessary.
The tables help to determine the soil class and provide information on the required fertilizer quantity. For substrate analyses, crops are divided into three groups with the respective nutrient target values and a calculation example in case of nutrient deficiency.
All tables are included in the accompanying manual of the LASA AGRO system.
