Sophisticated automation solutions for reliable soil, plant and fertilizer analysis

Managing soil fertility has become increasingly important for optimizing crop production and protecting the environment from contamination by runoff and leaching of excess fertilizer.

The increasing demand for reliable soil, plant and fertilizer testing requires a quick response to farmers from well equipped laboratories. For more than thirty years Skalar has been developing, a range of sophisticated analyzers for the automation of a wide variety of soil, plant and fertilizer analyses. All these analyzers produce accurate, fast and economical results.

Our automated solutions for soil, plant and fertilizer analysis

The SAN++® Series analyzer can handle large numbers of samples, saving labor and reagent costs, increasing accuracy and shortening laboratory response time. Soil, plant and fertilizer samples are analyzed according to well proven analytical methods. The analyzer has a flexible modular design and can be configured to meet the needs of any laboratory. Smaller workloads with one or two chemistries can be handled, but also bigger workloads with as many as 500 samples a day. Up to 16 parameters can be analyzed simultaneously and 4 different sample matrices can be introduced at once if required.

The PRIMACS SNC-100 analyzer automates the analysis of carbon and nitrogen levels (C/N ratio) in soil. This is important because nitrogen is the main element for plant development and carbon is essential for soil strucure. The PRIMACS SNC-100 has an integrated 100-position autosampler. High temperature combustion is used to provide fast, efficient and accurate analysis results for nitrogen (N), protein, total carbon (TC), total elemental carbon (TEC), total inorganic carbon (TIC) and total organic carbon (TOC) all in one unit.

PRIMACS™ SNC-100 - ceramic crucibles


  • Analyses of TC, TIC, TEC, TOC and N / Protein
  • Re-usable ceramic crucibles
  • Unique vertical sample introduction system
  • Automatic balance interfacing
  • Fast and environmentally clean analysis
  • 100 position autosampler

The SP2000 Series analyzer can process large quantities of soil samples every day. The soil-pH gives information about how to improve the quality of the soil, which will result in increased crop quantities and cost reduction. Besides pH analysis in soil, the analyzer can be extended with Electrical Conductivity (EC) measurement at the same time. It is always possible to adapt the analysis procedure according to the customer methodologies, each step in the automatic procedure is user definable, for example, the stirring time and amount of extraction solution to be added etc.

Our robotic analyzers can automate the determination of the clay fraction as well as the sample preparation of the lengthy particle size distribution analysis procedure according to ISO 11277. This procedure requires very precise timing steps, tasks which are much more easily performed by an analyzer rather than a human operator.
