Soil nutrients availability and decomposition of organic matter depends on microorganism but there are little available literatures on the possible effects of nutrients fixing chemicals and substances on the survival and population distribution of various microbes. ![]() Assessment of bacterial or fungal biomass, with separation of active biomass and total biomass, is much more easily performed than molecular assessments. But all is not hopeless, because if we use a more affordable level of resolution, we can summarize biology at a less finely resolved level. ![]() Fungal diversity is possibly not quite so great, but still beyond easy, or possibly more importantly, affordable, assessment, at least at this time. Recent estimates of species diversity in soil, and most likely in compost as well, puts molecular diversity in the millions of species of bacteria per kg of soil or compost. It seems beyond the capability of our limited resources, however, to comprehend the actual diversity of these organisms in soil or compost. The precise composition of each group in this food web varies with soil types (mineral composition, depth of horizons, structure, texture, etc), with organic food resources present, with prevailing temperatures, climate, etc, as outlined by the classic work by Hans Jenny. The soil food web consists of bacteria, fungi, including mycorrhizal fungi, protozoa, nematodes, micro arthropods and a range of aboveground predators, from earthworms to spiders, mice, birds, etc (Ingham et al. ![]()
