SOIL CHEMISTRY ANALYSIS
Basic Chemistry Plus Test
Includes organic matter & soil moisture content, pH, cation exchange capacity, % base saturation, electrical conductivity
Nutrients: nitrate nitrogen, sulfur, phosphorus, potassium, calcium, magnesium. Plus trace minerals: iron, copper, zinc, manganese and boron
Complete Chemistry Test
Includes all analyses in 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 do not include interpretations and recommendations of organic products.
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 & Basic Foodweb Plus
Quantifies total bacteria, total fungi, and presence/absence of protozoa and nematodes. Nematodes are a large group of tiny worms that can either benefit plants or damage plants. A diverse array of beneficial nematodes are a good indicator of healthy soils. This test provides us the information to develop a program to adjust bacterial, fungal, protozoa and nematode imbalances. Note: Basic Foodweb Plus add Active Bacteria & Active Fungi.
Nematode Biomass and Diversity
Quantifies exactly via extraction the biomass and diversity by ecological function, among the different nematodes. This test is the ensure no presence of pathogenic nematodes in your soils and composts, and to ensure that sufficient predators of pathogens, fungi and bacteria.
Determines the presence or absence of E. Coli and rates from High to Low to None.
Complete Quantitative Foodweb + Mycorrhizae
This test is available for soil samples only, not for compost or compost tea. It includes all assays in the Basic Foodweb plus active bacteria, active fungi and mycorrhizal colonization. Active bacteria/fungi are those that are currently cycling nutrients; total bacteria/fungi include active and dormant microbes. This test determines what percentage of the plant roots are colonized and can also detect signs of disease or other damage.
