As each layer is added, water it thoroughly so the pile is
evenly moist—like a wrung-out damp sponge that does
not give out excess water when squeezed. SuHcient
water is necessary for the materials to heat and
decompose properly. Too little water results in
decreased biological activity, and too much simply
drowns the aerobic microbial life. Water the pile, when
necessary, as you water your garden. The particles in the
pile should glisten. During the rainy season, some shelter
or covering may be needed to prevent waterlogging and
the less optimal anaerobic decomposition that occurs in
a waterlogged pile. (The conditions needed for proper
functioning of a compost pile and those required for
good plant growth in raised beds are similar. In both
cases, the proper mixture of air, soil nutrients, structure,
microorganisms, and water is essential.)
Compost Curing and Application Rates
Usually, a compost pile needs one turning to adjust the
moisture level and make the mixture more homogeneous
for complete breakdown. This should be done at about
the 3-week point, after the temperature of the compost
pile has peaked and fallen. A decrease in moisture
usually occurs at the same time, the color begins to
change to brownish from the original green and yellow,
and the compost’s odor begins to change from musty to
an earthy, freshly plowed soil aroma. The compost will
normally be ready about 2 months later.
