He notes three common mistakes surrounding soil biology.
“First, an exaggerated idea of the extent of soil biology has advantages. Second, the assumption that our soil has problems with soil biology. And finally, to solve the problems, increased sensitivity to unproven products or practices.”
“And in most cases, the ‘problems’ aren’t actually problems. A few proven practices will often suffice.”
“Here’s what you need to know about soil biodiversity. First, diversity itself doesn’t do anything. Rather than being an actual mechanism or cause – think pH, soil structure, disturbance, etc. – biodiversity is only correlated with mechanisms. It is not the cause of soil function, and therefore not as helpful in determining management.”
“Another perceived problem is not having enough soil microorganisms. Remember, the amount of life in your soil is directly related to the amount of food and habitat available.”
“Most of these ‘problems’ are not problems, and if they were, they would not be easily managed. Even the detection of these ‘problems’ is problematic. Many of our measurements of microbial traits, including microbial biomass fungal:bacterial ratio, enzyme activities and ratios, mycorrhizal abundance/composition, and C and N mineralization rates, are not necessarily representative of actual soil function or cannot be easily interpreted.”
“Rather than practices that produce inconsistent results, such as compost tea, inoculations or home brews, perhaps it would be better to focus on improving the physical environment of your soil, protecting your improvements and letting the microbes do their thing? You are the driver. Where do you want to go?”
