NOTES FOR AN ESSAY: CO~IPO$T IS
. Compost is a commons with the biospheric function to integrate the primary domains of air, water, and land-based minerals. Compost, as a physical substance, acu as. a I)'nch pin betwe:n the domains of air,' water, and land-based minerals, which arc also commons. J-Jumus, a word that is often misunderstood and misapplied in both senses. refers to completely decomposed organic mauer, and is the essential material rhat occurs in the end product from the ~many bio-chemical and biological processes within the overall decomposition process. "'Strictly speaJdng. humus is about 95-97% . humic acid and humatcs. One or its physical properties and the one that makes it a jin~ qW2 non value is that it holds water like a superefficient spoftge. Without its
presence, there is only a spurious presence of water on bureon rock surfaces bathed only in ,air, not water, until some event brings humus to that point (place) . and with it a. '.
