Compost Benefits
Your garden and lawn soil has living soil microorganisms that include
bacteria, algae, fungi, and protozoa. Without getting too technical lets
just say that a healthy soil has lots of biological life and these
organisms need organic matter (compost) to survive and thrive. This
living-soil-life helps with soil health, decomposition of organic matter,
replenishment of nutrients, humus formation, promotion root growth,
nutrient uptake, and herbicide and pesticide breakdown.
As your organic matter increases, your native earthworm population
will also increase in your garden soil. With the presence of
earthworms, you have the actions of soil their tunneling that increases
nutrient levels, water penetration, and aeration.

Compost Benefits Soil Nutrition
Compost helps modify and stabilize pH in your organic garden soil.
Compost will raise or lower the pH of your soil depending on your
existing garden soil, and what organic matter you add to the compost.
Compost made up of neutral to alkaline materials will increase the soils
pH. And the reverse is true as well. Acidic compost will decrease a soil
pH. Compost also helps protect the soil from pH level fluctuations.
Just because soil has nutrients doesn’t necessarily mean your plant
roots can utilize them. In poor soils (and dry soils), there is poor
nutrient exchange between the roots and the soil. Compost will
improve the soil’s nutrient exchange capacity allowing your plants to
utilize the nutrients more effectively. If your soils have little organic
material, you can bet that nutrient or fertility level is low. YOU NEED
COMPOST!
Compost Helps Control Plant Diseases
Compost adds organic matter into your garden soil that increases the
population of soil microorganisms, which in turn help control plant
diseases. There is research that actually shows that certain soil
microorganisms “suppress” certain plant diseases.
Compost Provides
a "Ton" of Nutrients
Ok maybe not a ton but compost provides many nutrients in the form
of micro and macronutrients. Compost provides a good amount of
macronutrients NPK (nitrogen, phosphorous, and potassium) but it’s
the micronutrients are the real heroes of your compost. The organic
matter in the soil helps release these nutrients in a stable and slow
way that is more beneficial to your plants.
Compost and Commercial Organic Fertilizer
Does Compost do away with commercial fertilizers? The answer is
maybe, no and not necessarily. I know that’s not a straight answer,
but there really isn’t one. Depending on what nutrients your soil is
lacking (or in abundance) certain organic fertilizer will be necessary. In
addition to providing nutrients (micro and macro), compost helps
make fertilizer more effective in the soil.
Compost Benefits Soil Structure
Composts will enhance your garden soil’s structure. If the soil is sandy
and has rapid drainage, compost can help the structure by adding
more bulk with humus and organic matter and increase the soil’s water
holding retention abilities. Soils with fine soil structure (clay, clayloam) will benefit, because compost will increase soil porosity
(sponginess) by adding humus and organic matter. Compost will also
make these fine-textured soils easier to work with and erosion
resistant.
Compost in both the short term and long term provides enormous
benefits to your soil structure. In the short term, compost helps
prevent compaction (an enemy to plant roots and soil organisms!) in
fine structured soils. It increases the soil’s water holding retention
abilities, and improves soil structure in sandy soils.
This brings us to the long-term compost benefits. In addition to more
of the above short term benefits the use of compost increases the soil
humus content. Humus acts like glue that holds all the soil particles
together, and it helps prevent erosion and increases a soil’s moisture
holding ability. Humus will also make the nutrients more available to
the garden plant’s roots.

Improved Soil Structure
Saves on Water Usage
Compost will provide more water holding retention capacity that will in
turn increase drought tolerance and better water usage in the soil.
With better water holding capacity, you will have to irrigate less often
Using compost offers economic benefits
Using compost can reduce the need for water, fertilizers, and
pesticides. It serves as a marketable commodity and is a low-cost
alternative to standard landfill cover and artificial soil amendments.
Composting also extends municipal landfill life by diverting organic
materials from landfills and provides a less costly alternative to
conventional methods of remediating (cleaning) contaminated soil.

Compost helps cleanup (remediate) contaminated soil
The composting process has been shown to absorb odors and treat
semivolatile and volatile organic compounds (VOCs), including heating
fuels, polyaromatic hydrocarbons (PAHs), and explosives. It has also
been shown to bind heavy metals and prevent them from migrating to
water resources or being absorbed by plants. The compost process
degrades and, in some cases, completely eliminates wood
preservatives, pesticides, and both chlorinated and nonchlorinated
hydrocarbons in contaminated soils.
Compost helps prevent pollution
Composting organic materials that have been diverted from landfills
ultimately avoids the production of methane and leachate formulation
in the landfills. Compost has the ability to prevent pollutants in
stormwater runoff from reaching surface water resources. Compost
has also been shown to prevent erosion and silting on embankments
parallel to creeks, lakes, and rivers and prevents erosion and turf loss
on roadsides, hillsides, playing fields, and golf courses.
