Organic
matter in the soil ensures a continuous food source for soil microbes.
As soil bacteria metabolize organic matter, they help maintain good soil
structure by developing compounds that cement small soil particles
together into aggregates, allowing for both increased drainage and
moisture retention. Microbes also change the organic matter into
inorganic nutrients that can be used by growing plants.
The
physical properties of the soil are equally important. Space between
soil particles can affect aeration and soil moisture both of which affect root growth.
In addition, space between soil particles and particle size directly
affect microbial activity. As the physical properties and mineral
structure of the soil improves,
run off lessens and erosion and nutrient loss is decreased.
