FOGII Digital Soil Calcimeter

The FOGII Digital Soil Calcimeter™ with automatic temperature compensation (patented) offers dramatically improved levels of performance, productivity, reliability, ease of use and flexibility.

The FOGII Digital Soil Calcimeter™ is the ideal tool for agriculture scientists and farmers. Testing soil every two years and applying frequent small amounts of lime can help farmers avoid top soil acidification. Calcium carbonate is an important parameter for Soil Science and Precision Agriculture (PA) or Site Specific Crop Management (SSCM).
