Drought Resistance Response of Tall Fescue Established in Disturbed Urban Soils Utilizing Biosolids

摘要

Urban development is a primary cause of soil degradation. As populationscontinue to swell, development extends further from city centers and encroaches into surrounding rural and forested areas. A result of population growth is increased biosolids production. Increasing regulations on agricultural biosolids land applicationhave resulted in wastewater-treatment plants seeking alternative means of land application. Contractor use of biosolids to improve disturbed urban soils following construction offers a beneficial use and alternative means of disposal for wastewater-treatment plants, while also possibly reducing fertilizer and irrigation requirements.
