Biological Benefits of Compost
The benefits of composting go beyond the exterior, creating a nutrient-rich, biological compound that is favorable for both your landscape and reducing your waste.
Healthy Soil Biota
Plant activity is largely based on the presence of organic matter. Soil microorganisms include bacteria, protozoa, actinomycetes and fungi. They are not only found within compost, but proliferate within soil media.
Microorganisms play an important role in organic matter decomposition which, in turn, leads to humus formation and nutrient availability. Microorganisms can also promote root activity as specific fungi work symbiotically with plant roots, assisting them in the extraction of nutrients from soils.
Sufficient levels of organic matter also encourage the growth of earthworms, which through tunneling, increase water infiltration and aeration.
Fewer Plant Diseases
The level and type of organic matter and microorganisms present in soils influences disease incidence in many plants. Research has shown that increased population of certain microorganisms may suppress specific plant diseases such as pythium and fusarium as well as nematodes.
