Biosolids Safe for Land Application, UA Researchers Find

Biosolids are frequently applied directly to cropland, pastures or timberland, where they decompose, furnishing nitrogen, phosphorus and potash to growing plants. This method offers a more ecologically sound and practical alternative to domestic waste disposal than landfills or incineration, that may result in water or air pollution.

Organic Mulches Enhance Overall Plant Growth

Nutrient cycles have been studied thoroughly in forested and agricultural ecosystems (Facelli and Pickett 1991; Wardle 1992; Attiwell and Adams 1993; Mary et al. 1996). In contrast, nutrient cycling has received little attention in ornamental landscapes, and the effects of mulch on soil fertility have been largely ignored.

Using Organic Waste Presents A Win-win Situation For Municipalities, Agriculture

The concept of using organic wastes as fertilizer is not new. Before the industrial age in the 1940s when synthetic N fertilizer became widely available, animal manure and human waste were the primary amendments to agricultural soils for improving crop yields around the world. Crop fertilization with organic waste has received renewed interest as municipalities face increasing disposal problems. Florida's human population growth from 4 million in 1955 to 16 million in 2000 is among the highest in the nation. Prohibition of waste dumping in streams and oceans, diminishing landfill space, skyrocketing landfill costs, and concerns over air pollution from incineration of waste have contributed to a strong public interest in finding alternative, environmentally sound solutions to waste disposal

Biosolids and Bioaerosols: The Current Situation

Land application of biosolids is giving rise to more and more apprehension, or even opposition, especially from people living next to application sites. However, the scientific studies indicate that the risks for exposed workers, such as farmers, are relatively low and even extremely low for people living in the vicinity of the sites where biosolids are being applied. Available information also suggests that the potential health risks are relatively lower than those associated with the management of manure….
