Qualitative Potting Soil Assessment

Correct Soil Sampling: To get an accurate picture of the overall quality of your soil, samples must be taken from different areas and combined. Take approximately a 1 cup sample from at least 4 different areas of your garden and mix thoroughly. The more samples the better, especially if you use a completely separate container for each plant.

Bring us a 2-cup sample of your mixed soil and we will do an on-site qualitative analysis, providing recommendations free of charge.

Third Party Testing

We do not do chemical or quantitative analysis, as we specialize in microbes that are constantly moving and cycling nutrients. This makes them difficult to asses, resulting in inaccurate and sometimes misleading test results.

If you do not suspect that there is a severe nutrient imbalance or specific pathogen present, we would suggest continuing with weekly compost extracts and allowing the microbes to continue their constant efforts to bring the soil to optimum health and facilitate maximum productivity of their beloved plants. However, should you desire a soil or microbial analysis, we have a few labs that we would recommend.

MycoRoots offers mycorrhizal colonization testing as well as mycorrhizae spore count. We recommend this test for validation of spore count in mycorrhizal inoculant products. Mycorrhizal colonization testing measures what percent of a plant’s root system is colonized by mycorrhizae. This test is useful to determine if the mycorrhizae you are using is actually effective.
