Another addition to help build up your #soil #organic matter would be to incorporate #arbuscular #mycorrhizal #fungi (#AMF) into your growing routine.

There are multiple producers you can purchase the #inocculum from, i just purchased a standard bag 2.2 lb bag from xtreme-gardening.

Product availability might vary depending where you are located.

They offer 2 different products for AMF:

1: Standard propagules that can be added while planting or transplanting, the spores will sporulate once roots start to come in contact. Particles vary in size, not ideal for fine mist sprayers or a system that can clog easily (Propagules = cheaper price)

2: WP (Wettable Powder) if you plan on applying compost tea or #biofertilizers, this would be a good product to look into. Mix some powder into your brew to be applied and water in. Same concept applies for the activation of the sporesin regards to needing roots to create a relationship with. (WP = Higher price)

Teaming with AMF, will increase the root surface area of your plants in turn increasing your soil organic matter over the growing seasons. 

One caveat with "Root fungus" is they need living roots to coninually grow and stay active, if you can maintain covercropping (or no till) there should be a continual supply of spores in the #rhizosphere season after season reducing your input cost while maintaining the benefits. The benefits don't compound year over year but the benefits gained would remain constant.

Here is the site i picked mine up from:

I have no affilation with the company or product, nor do I recieve any compensation for any products purchased.

Hope this helps.
