Human waste by products, euphemistically referred to asbiosolids, are generated at tremendous rates in the Baltimore-Washington Metro area. Much of this resource is currently land applied to agricultural land. Additional biosolids are trucked outof state. As the WQIA of 1998 takes effect, the land base may not be available for land application. Alternative uses for this resource are preferable to landfilling. Towards this goal, three MCE researchers have developed a project to assess the growth, survival, and long-term sustainability of hybrid poplar; water quality considerations associated with deep row biosolid application; and the profitability of this technology. Field days for agency and MCE personnel have been heldand fact sheets are available. A masters thesis has been published andpapers are forthcoming.
Poultry Litter Management/Utilization
Stockpiles-Eastern-shore-specific impacts from using covers. Increases flow of water, so increases nutrient loss in surfacewater.... counter intuitive. Conversely reduces infiltration, so reduces potential for transport to groundwater. Conclusion: allowing piles to absorb water probablyslightly reduces total nutrient loss because a great deal of water isthen evaporated and never becomes the transport mechanism forpollution. The overall system appears to be transport-limited.
This new project will examine earth pads, soil cement pads and cement pads to determine what impacts various types of elevated pads have on subsurface nutrient transport. Suction lysimeters will be placed below pads to collect water samples and subsurface flow will be estimated. Six or eight demonstration sites in the lower five counties of the shore will have pads.

Immobilization of Soluble Phosphorus in Animal Waste with SWAN-Gypsum and Iron Oxide Filter Cake Co-Products. Felton, G.K., K.J. Hughes, and L.J. Ottmar Sponsor: Maryland Industrial Partnerships and Millennium Inorganic Chemicals, Inc. Funding: $309,676 Duration: February 2000 - January 2002 Role: Principal Investigator Description: Two locally produced materials that contain both calcium and iron, SWAN-gypsum (SWAN) and Iron Oxide Filter Cake (FC), will be tested for suitability as amendments to manures. These amendments form insoluble metal-phosphorus complexes, thereby decreasing phosphorus concentrations in soil pore water and surface runoff. Methods of investigation include laboratory incubation experiments and the construction of phosphorus sorption isotherms, as well as greenhouse and field plot experiments. 10. Phosphorus Removal from Animal Waste with SWAN-Gypsum. G.K. Felton, K.J. Hughes Sponsor: Millenium Inorganic Chemicals Inc. Funding: $175,000 Duration: 1999 - 2000 Role: Principal Investigator We propose to: (1) develop a single tank phosphorus treatment system, suitable for agricultural use, that utilizes chemical precipitation with SWAN-gypsum (a locally produced industrial byproduct with an extremely high P sorbing capacity in a neutral pH environment ) as a means of removing soluble phosphorus from animal wastewater; (2) determine the suitability of the solids generated in the precipitation tank and poultry litter amended with SWAN-gypsum as a soil amendment in terms of both soluble P in leachate and basic soil fertility; and (3) demonstrate, on-farm, the viability of the design under day-to-day operational conditions. The process generates a liquid effluent and solid waste that is sustainable and economically feasible in terms of both time and money and is easily incorporated into existing farm wastewater treatment and handling systems. The resulting products maintain the nitrogen fertilizer value of both liquid and solid animal waste and is an agronomically valuable soil amendment that can be applied to local agricultural land based on crop nitrogen requirements. 9.
