Dear wayne, while going through old unread E-mails I discovered yours. In the case of both the types of manures (vermicompost and biogas effluent), the minerals come from the biomass itself. The organisms involved in the process primarily remove the carbon from the biomass, leaving the minerals behind. There is another process, which actually adds water soluble minerals to the compost. In this process, biomass is composted by layering it alternately with soil. In this process, the biomass serves as the carbon source for the micro-organisms in the soil. With such an abundant supply of organic carbon as food, the microbes absorb minerals directly from the soil and multiply their numbers. The resultant microbial biomass has more minerals in it than the minerals in the original biomass, and because the minerals form a part of the microbial cytoplasm, they are easily dissolved in water and therefore become easily available to plants growing in the field.
