“…However, some studies of the application of wastewater sludge have yielded variable results, or have suggested a drop in Zn levels (Garcia et al, 1981;Sikora et al, 1980). (Giordano, 1979;Ronrney et al, 1976).…”

We tested the effects of wastewater from olive processing, applied alone or in combination with different mineral complements, in pots containing calcareous soil. An initial barley crop, and a subsequent ryegrass crop, yielded information on the direct and delayed effects, respectively, of the by-product on Zn and Cu assimilability in the soil-plant system. As a direct effect, the application of wastewater tended to decrease Zn assimilability, but the delayed effect showed the opposite trend, especially when the by-product was added together with N- 305

“…However, when the levels of these chemicals are elevated they can act as toxins (Qi., 2011), disrupting the biochemical processes within plants and impacting growth and development. In addition, since heavy metals can be stored in plant tissues, they can potentially accumulate in the food-web (Sikora et al, 1980;McLaughlin et al, 1999). The rates of biosolids application can have an effect on the accumulation of heavy metals in the tissues of plants (Chang et al, 1984).…”

Examining the Effects of the Runoff Originating From Biosolids Amended Soil Plots on the Biogeochemical Nitrogen Cycle and Eutrophication

One of the disposal methods for biosolids (nutrient rich organic matter that settles out of the wastewater during wastewater treatment process) is through application on agricultural fields as organic fertilizer. In order to determine the effects of runoff originating from biosolids treated fields on the nitrogen biogeochemical cycle and eutrophication of surface water, a lab-scale mesocosm experiment was carried out, simulating agricultural fields and thermally stratified water systems receiving agricultural runoff. A significant difference was found between the effects of the runoff from unfertilized soil plots and plots fertilized with biosolids. The findings indicate that the majority of incoming nitrogen is either denitrifed, lost to the sediment or is accumulated in the water column as nitrate. Further, it is hypothesised that the majority of incoming organic nitrogen was rapidly mineralized to ammonium in the hypolimnion, which has the potential to increase nitrogen bioavailability to primary producers in the epilimnion.

“…In the early 1970's, the Washington Suburban Sanitary Commission purchased hundreds of acres of land in the counties surrounding Washington, D.C. for the purpose of burying biosolids in trenches at rates approximately equal to and greater than 383 Mg/ha (171 dry tons per acre). While the production of annual corn crops on treated areas was researched (Sikora et al, 1980), no forest crops or other deep-rooted perennial crops were intentionally established to utilize the large reservoir of nutrients.

“…Researchers (Sikora et al, 1979b(Sikora et al, , 1980Walker, 1974) noted some interesting characteristics of the biosolids in the trenches. Observations included an analysis of the original sludge sample and then the progression of the sludge starting at 22 months after entrenchment.…”

“…Monitoring of nitrogen and chlorides in biosolids and soils below trenches was conducted in an effort to determine potential for leaching (Sikora et al, 1980). Chloride, a water-soluble anion commonly found in biosolids, does not interact chemically with most soils and provided an indication of water flow and maximum leaching potential through the biosolids and soil profile.…”

Deep row incorporation of biosolids at rates of 383-658 Mg/ha(171 to 294 dry tons per acre) using hybrid poplar involves the placement of biosolids into trenches that are immediately covered with overburden, eliminating odor problems and maintaining the biosolids in a fairly stable, anaerobic environment. The site is then planted with hybrid poplar trees, the roots of which provide a natural recycling system that utilizes the nutrients over a six-year period in most cases. at 15 and 60 cm may have stabilized or decreased slightly to 1900 and 400 mg/L, respectively. While ammonium levels at 30 and 60 cm may have leveled off, additional suction lysimeters were installed during the summer of 2007 at 120 cm below the biosolids trench in all plots to better understand ammonium movement in the profile.
