Biological Assessments
Looking at soil life under a microscope. We do direct microscopy focused on four main groups: bacteria, fungi, protozoa, and nematodes (both helpful and harmful), and we measure the biomass of the active representatives. These microorganisms drive the nutrient cycle to make nutrients available for crops, build soil structure, and reduce compaction. The web also includes arthropods and larger animals, but they aren’t part of this analysis. The test doesn’t identify exact species or detect specific pathogens, but it shows if the soil, compost, and liquid amendments have enough beneficial microbes to support strong and healthy plants, as well as soils free of weeds, and with good structure.
We talk about...
Fungi to bacteria biomass
Bacteria and fungi break down the minerals and store nutrients. They also help build soil structure—creating pores and aggregates—and improve the soil’s ability to hold water.
The ratio of fungi to bacteria is important because the higher the more favorable soil conditions are for crops and less favorable for weeds.
Protozoa and nematodes
These microorganisms are indicators of healthy soil. Their role is to feed on bacteria and fungi, releasing nutrients in a form that plants can use. If these predators are not present, the natural nutrient cycle cannot properly supply plants.
They also help build soil aggregates and improve soil structure.

As we rely on the microscope to give us a valuable picture of the space and the task's context, we also understand the need to combine these findings with additional testing methods for soil and plants to build a more complete understanding about the ecosystems generally.
