Approximately 77 percent of the Biosolids applied to land in the United States is applied to agricultural land. This includes land used to grow food-chain crops such as corn and soybeans, land used to grow feed crops for animals, and land used for pasture. Nutrients in these materials help the crops to grow. The nutrients in these materials help increase the rate at which trees grow thus shortening wood production cycles. The Biosolids provide nutrients and condition the soil so that vegetation can grow on the reclaimed land.
Vegetation reduces soil erosion and helps make the land productive again.
Biosolids and Industrial Waste Products that meet these standards, which are designed to protect human health and the environment, can be applied to the land. Indiana Water Pollution Control Assoc.
