The closest analogies to composting I can imagine are concocting
similar fermented products like bread, beer, or sauerkraut. But
composting is much less demanding. Here I can speak with authority,
for during my era of youthful indiscretions I made homebrews good
enough have visitors around my kitchen table most every evening.
Now, having reluctantly been instructed in moderation by a liver
somewhat bruised from alcohol, I am the family baker who turns out
two or three large, rye/wheat loaves from freshly ground grain every
week without fail.
Brew is dicey. Everything must be sterilized and the fermentation
must go rapidly in a narrow range of temperatures. Should stray
organisms find a home during fermentation, foul flavors and/or
terrible hangovers may result. The wise homebrewer starts with the
purest and best-suited strain of yeast a professional laboratory can
supply. Making beer is a process suited to the precisionist
mentality, it must be done just so. Fortunately, with each batch we
use the same malt extracts, the same hops, same yeast, same
flavorings and, if we are young and foolish, the same monosaccarides
to boost the octane over six percent. But once the formula is found
and the materials worked out, batch after batch comes out as
desired.
So it is with bread-making. The ingredients are standardized and
repeatable. I can inexpensively buy several bushels of wheat- and
rye-berries at one time, enough to last a year. Each sack from that
purchase has the same baking qualities. The minor ingredients that
modify my dough's qualities or the bread's flavors are also
repeatable. My yeast is always the same; if I use sourdough starter,
my individualized blend of wild yeasts remains the same from batch
to batch and I soon learn its nature. My rising oven is always close
to the same temperature; when baking I soon learn to adjust the oven
temperature and baking time to produce the kind of crust and
doneness I desire. Precisionist, yes. I must bake every batch
identically if I want the breads to be uniformly good. But not
impossibly rigorous because once I learn my materials and oven, I've
got it down pat.
Composting is similar, but different and easier. Similar in that
decomposition is much like any other fermentation. Different in that
the home composter rarely has exactly the same materials to work
with from batch to batch, does not need to control the purity and
nature of the organisms that will do the actual work of humus
formation, and has a broad selection of materials that can go into a
batch of compost. Easier because critical and fussy people don't eat
or drink compost, the soil does; soil and most plants will, within
broad limits, happily tolerate wide variations in compost quality
without complaint.
Some composters are very fussy and much like fine bakers or skilled
brewers, take great pains to produce a material exactly to their
liking by using complex methods. Usually these are food gardeners
with powerful concerns about health, the nutritional quality of the
food they grow and the improved growth of their vegetables. However,
there are numerous simpler, less rigorous ways of composting that
produce a product nearly as good with much less work. These more
basic methods will appeal to the less-committed backyard gardener or
the homeowner with lawn, shrubs, and perhaps a few flower beds. One
unique method suited to handling kitchen garbage--vermicomposting
(worms)--might appeal even to the ecologically concerned apartment
dweller with a few house plants.
