Use, soil benefits and cautions

Biodynamic® compost, 1.25 dry qt is one bag makes 10 gal of extract. Screened to 1/8". Microscope verified. Flat rate shipping to the lower 48. This is the role it plays in the Cure Soil approach. The reason to use it is the job described here, not the idea that adding more of everything makes soil healthier.

Use it when The Plan · Biology identifies that job and the linked protocol explains the conditions. Compare it with the named part of your soil report before choosing a rate. If you do not have the relevant reading yet, ask Cure Soil to set the rate instead of guessing. Where a label applies, follow that label.

Do not use it simply because another garden needed it. Too much of an input can crowd out another nutrient, stress the soil's living community, or hide a water problem. For living products and extracts, also keep oxidizers such as bleach and chlorine away: they kill the organisms you meant to bring into the soil. Check the warnings in the matching protocol before combining anything.

To tell whether it helped, note the reason you chose it, then compare the same bed and the same relevant report measure next round. Look for the expected change in the roots, soil or measured shortage rather than declaring success from a single greener leaf. If the signal did not move, pause and reassess before repeating the application.
