Environment Celebration Institute

Lab Testing

The methodology for analyzing soil health based on identifying and quantifying soil micro-organisms was developed by Dr. Elaine Ingham, Ph.D. After 30+ years of studying and improving soils, she and the Soil Foodweb, Inc. have identified optimal soil microbe ratios for compost, compost teas, crops, landscape plants, trees, and shrubs. Soil, compost, and compost tea/extract samples sent to these labs below will be analyzed for microbial diversity and compared with optimal ranges.

Please note: Taking soil samples in winter —- Most soil organisms are dormant when soil temperature is low (<40 F). Thus better times to take soil samples are in fall or spring.

Samples are ONLY accepted on Tuesday, Wednesday, or Thursdays. This gives the technicians time to complete the testing. Pre-payment MUST accompany the submissions form, we do not do invoicing. We will not be able to do your test if received on other days or without payment. Please use fedex OVERNIGHT to send samples because the Institute is up in the mountains and fedex is the only service that is guaranteed to arrive on time. Take the sample the day you send it. Only send 1/4 cup of dry material, more is not necessary, or 1/4 small water plastic bottle full of liquid teas. Take samples of soil using an apple corer. We only need a sample from the top 1-3 inches of soil. Please fill out the submission form and the chain of custody form and send to us with your payment.

Testing: Soil, Compost,  Compost Tea, and Extract (Qualitative Assessments), Total Bacteria (actinobacteria, rods, cocci), Total Fungi (colored wide diameter vs narrow, clear), Protozoa (flagellates, amoebae, ciliates), Nematodes (to functional groups), Total Foodweb Package (Bacteria, fungi, protozoa, nematodes). Click on the link “Soil.Foodweb.Order.Form.a.pdf” to download the form to submit your samples.

Our laboratory opened in 2007 to serve as both a research and soil testing facility. Our state-of-the-art equipment enables us to research and evaluate the efficacy of new products, provide in-house quality control, and learn more about how microbes affect soil fertility and plant health. Our lab performs soil chemistry and soil biology testing. this proactive approach helps us to understand just what your soil requires, both chemical and biological, allowing us to custom design a program based on your regional soil type(s). Types of testing include: Basic Plus test, Complete Chemistry Test, Qualitative Microbe Package, Basic Foodweb, Complete Foodweb, Complete Foodweb + Mycorrhizae. Interpretations of test data can be included or excluded. If you want organic product recommendations based on a biological soil test, a phone consultation will need to be scheduled with one of our staff members.

Testing: Compost and soil testing for the presence and quantity of soil food web elements. Reports include guidance for interpreting of the result and initial advice on steps needed for improvement. We accept samples from all of the UK providing they are sent on a next day delivery. Please email or phone to set a date for testing to ensure a prompt service. Our vision is to fully replace chemical agriculture with the biological approach developed by soil food web scientists, with methods pioneered by Dr. Ingham.
