Soil is a mixture of clay like and sand like particles. These serve
as a substrate in which the life processes of microbes take place. These
tiny creatures 'eat' or 'process' organic material, changing its
molecular state. The resultant material in the soil is what plant roots
are able to absorb. So having the right amounts of air, organic material
and water in your soil, with the best mixture of sand and clay like
particles is ultimately what gives your soil the capacity to grow. It is
what determines how much growth takes place, how vibrant and active the
whole system of your garden is or can become. The life of planet earth
is in the soil. Making and building soil is something every person on
the planet should take some level of responsibility for. You can start
with a compost heap and add the proceeds of a bokashi bin and a worm
farm to your soil as well. This sounds gross to the uninitiated but is
really not. What's gross is the level of food waste that humanity
indulges in without ever considering the obvious consequences.
It
is important that we look after this life. Too few people understand how
bacteria 'fix' nitrogen in soil, how Oxygen, water, nitrogen and living
creatures are all involved in an endless cycle and the more material we
remove from this cycle by not reintroducing it to the soil the more
tenuous life on planet earth is going to become.
To
keep a variety of healthy microbes in soil it is necessary to feed them
with as wide a variety of organic materials as possible, further than
that, if your planting arrangement, the pattern in which you have
companion planted your crops, herbs and barrier plants, is diverse and
varied, your soil health and structure will stabilise into an optimal
condition, resulting in growth and health that is unsurpassed. Adding manure to trigger nitrifying reactions in the soil is a common practice, it is however advisable to allow time to prevent contamination by manures.
