Soil
is made up of a mixture of mineral particles, decaying organic matter and
living organisms. It is very much a
living thing –
Soil
is populated by an amazing variety of living creatures, ranging from tiny
microbes such as bacteria and fungi (microbeasts), to smaller insects such as
centipedes and other animals such as worms (minibeasts) and larger animals such
as moles and rabbits.
A
single teaspoonful of soil contains over 4 billion micro-organisms.
Bacteria,
an essential group of soil micro-organisms, are responsible for much of the
decomposition of organic material in soils. They are usually present in top
soils in very large numbers and play an important role in converting more inert
forms of nitrogen to ones that can more readily be taken up by plants. |
