Phosphorus-acquisition strategies of canola, wheat and barley in soil amended with sewage sludges

Growth, yield, and fruit quality of pepper plants amended with two sanitized sewage sludges.

Organic wastes such as sewage sludge have been successfully used to increase crop productivity of horticultural soils. Nevertheless, considerations of the impact of sludges on vegetable and fruit quality have received little attention. Therefore, the objective of the present work was to investigate the impact of two sanitized sewage sludges, autothermal thermophilic aerobic digestion (ATAD) and...

Organic chemicals in sewage sludges.

Sewage sludges are residues resulting from the treatment of wastewater released from various sources including homes, industries, medical facilities, street runoff and businesses. Sewage sludges contain nutrients and organic matter that can provide soil benefits and are widely used as soil amendments. They also, however, contain contaminants including metals, pathogens, and organic pollutants. ...

Chemical and Biological Phenomena Observed with Sewage Sludges in Simulated Soil Trenches

Chemical and biological observations were made on sewage sludge in a simulated trenching system in the greenhouse. Limed and unlimed raw and digested sludges were placed in simulated trenches in soil profile boxes in which corn (Zea mays L.) was sown. During the 160-day growth period, roots penetrated entrenched digested sludge and root growth proliferated throughout the sludge. Root penetratio...
