Analyses & Pricing

Docterre’s laboratory services provide microbial analyses to determine the health of the ecological systems present in soil, compost, root systems, and agricultural products.

What type of analysis do I need?

Ecological Profile Analysis

The base analysis and the first step in any diagnostic process. If you are testing soil, compost, or an agricultural product for the first time in a season, this is always the first step.

Active Biomass Analysis

An optional add-on to the Ecological Profile Analysis. Clients may choose to add this analysis if seeking to understand the active fungal and bacterial biomass relative to their total biomass in the soil or compost.

Both of these analyses can be applied to soil, compost, or agricultural products.

Supplemental analyses are available for researchers and soil professionals

What to expect from each of these analyses



Ecological Profile Analysis

$150 per sample

This qualitative analysis will determine the presence/absence and balance of the entire microbiome of the soil/compost/product in question.


This analysis provides the following data: 


Beneficial organisms
  • Total bacteria biomass (μg/g)

  • Total fungal biomass (μg/g)

  • Total amoebae (#/g)

  • Total flagellates (#/g)

  • Total actinobacteria (μg/g)

  • Presence of bacterivore nematodes (#/g)

  • Presence of fungivore nematodes (#/g)

  • Presence of predator nematodes (#/g)


Non beneficial organisms
  • Total Oomycete biomass (μg/g)

  • Total ciliate biomass (#/g)

  • Presence of root feeding/parasitic nematodes (#/g)

  • Pathogen and disease bacteria (yes or not applicable)


Facultative anaerobes
  • Bacteria (“Yes” or “Not Applicable”)


Active Biomass Analysis

$50 add-on to Ecological Profile Analysis per sample

This analysis quantifies the total and active biomass of fungi and bacteria. The active biomass of both fungi and bacteria represent the portion of these organisms actively cycling nutrients, reproducing and producing enzymes in the soil or compost. 


This analysis provides the following data: 

  • Total Beneficial Bacterial Biomass and Diversity (μg/g)

  • Active Beneficial Bacterial Biomass and Diversity (μg/g)

  • Total Beneficial Fungal Biomass and Diversity (μg/g)

  • Active Beneficial Fungal Biomass and Diversity (μg/g)



More specialized analyses are available on request, or may be suggested to a client as a follow up to the Ecological Profile Analysis when the results suggest a specific issue needing further investigation. 

The Nematode Biomass and Diversity analysis is commonly requested by researchers and soil professionals. To reserve, send an email with a description of your needs and we will send you a private link to book the lab reservation.


Nematode Biomass and Diversity

$100 per sample

This analysis isolates the nematode population so that we are able to assess the quantity in biomass and in diversity by ecological function. We also measure the comparative biomass among the different nematodes. This test offers a much more thorough understanding of the nematode populations as compared to the type of nematode analysis offered in our Ecological Profile Analysis


This analysis identifies any presence of pathogenic nematodes in your soils and composts, and to ensure that sufficient predators of pathogens, fungi, and bacteria are present in your soils and composts. Without the proper biomass and diversity of nematodes, nutrient and mineral solubility are low, risk of plant parasites are high, and fungal populations are significantly less stimulated. Nematodes are one of the most important biological indicators of stress in soil systems.


  • Beneficial Nematode Biomass

  • Beneficial Nematode Diversity by ecological function (bacterial, fungal, predator)

  • Pathogenic Nematode Biomass

  • Pathogenic Nematode Diversity (parasitic nematodes, switchers)

Fungal to Bacterial Ratio Analysis

$60 per sample

Desired microbial communities varies among different plant communities, which in turn determines the varying nutritional requirements of these plants. We use this test to determine the actual balance between fungi to bacteria is in your soil/compost/product, and by providing us information about the desired plants, we can compare your results to the desired range. 


  • Total Beneficial Fungal Biomass and Diversity (μg/g)

  • Total Beneficial Bacterial Biomass and Diversity(μg/g)

  • Fungal to Bacterial Ratio
