SOIL CHEMISTRY ANALYSIS

Soil Testing Chemistry ExampleBasic Chemistry Test
Includes organic matter & soil moisture content, pH, cation exchange capacity, % base saturation, electrical conductivity
Nutrients: nitrate nitrogen, sulfur, phosphorus, potassium, calcium, magnesium

Basic Plus Test
Includes all Basic Test analyses plus trace minerals: iron, copper, zinc, manganese and boron

Complete Chemistry Test
Includes all analyses in Basic and Basic Plus. Comparison of Melich 1 and Melich 3 extractable nutrients informs us of the total amount of nutrients available in the soil versus the amount of nutrients which are readily plant-available.

**All Soil Chemistry Tests include interpretations and recommendations of organic products.


SOIL BIOLOGY ANALYSIS

Soil Testing Biology Results

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

 

Qualitative Soil Food Web Package
Determines the presence or absence of microbes (bacteria, fungi, ciliates, amoebae, and flagellates) and rates them from Not Present to Very High Levels. Also includes E.coli, pH, electrical conductivity, and percent organic matter. While specific recommendations cannot be determined from this assay, it will give you a general overview of what is present/absent from your soil, compost, or compost tea.

Basic Foodweb
Quantifies the biomass ratios of total/active bacteria and total/active fungi. This test provides us the information to develop a basic program to adjust bacterial and fungal imbalances. Active bacteria/fungi are those that are currently cycling nutrients; total bacteria/fungi include active and dormant microbes.

Complete Foodweb
Quantifies total and active bacteria, total and active fungi, and presence/absence of protozoa. Eventually we will also offer nematode identification. Nematodes are a large group of tiny worms that can either benefit plants or cause disease. A diverse array of nematodes is a good indicator of healthy soils.

Complete Foodweb + Mycorrhizae
This test is available for soil samples only, not for compost or compost tea. It includes all assays in the Complete Foodweb plus mycorrhizal colonization. This test determines what percentage of the plant roots are colonized and can also detect signs of disease or other damage.
