Compost is Beneficial!
Compost contains macro and micronutrients usually missing in synthetic fertilizers. Unlike synthetic fertilizer, compost releases nutrients gradually — over months or years. Compost enriched soil absorbs fertilizers better, as such fertilizer runs off to pollute waterways.
Compost brings & supports diverse life in the soil. Bacteria, fungi, insects, worms and more support healthy plant growth. Compost can curb diseases and harmful pests that could overwhelm poor, lifeless soil.
Compost boosts healthy root systems. This decreases runoff. Compost can reduce or erase the use of synthetic fertilizers. A 5% increase in organic material quadruples the water holding capacity of soil.
