Traditional soil tests measure the physical and chemical properties of soil, and that is valuable, but soil is a living, dynamic and continually changing ecosystem and requires a more holistic approach with a microbiological component for a more complete soil assessment. By digging deeper into the physical, chemical and biological interactions we can make improved agronomic recommendations for higher yields and greater profit. The biological composition of the soil reflects the presence of disease suppressing and bio-stimulating microorganisms in the rhizosphere.
