“…Apparent recovery of fertiliser N in the soil and crop after cut 1 of 1996 was, however, less than 25%. Cumulative recovery of fertiliser N over the duration of the experiment averaged 27%, much lower than the 65 to 85% recovery of fertiliser N by forage grass reported in previous studies (Kiemnec et al 1987;Sullivan et al 1997). Similarly, despite the much higher estimates of plant-available N applied as biosolids or fertiliser than recovered in the forage harvest, elevated soil inorganic N after cut 1 in 1996 was measured only for the highest biosolids rate.…”

“…Apparent N recovery of biosolids N applied to forage grass was estimated at 16 to 28% (Warman 1986), 22 to 46% (Sullivan et al 1997), 23 to 30% (Kiemnec et al 1987), and 28 to 40% (Cogger et al 1999). The fertiliser N equivalency of biosolids N, i.e., the ratio of the apparent recovery of biosolids N in comparison to the apparent recovery of fertiliser N, from a series of studies averaged 32 and 50% for the first and second years of biosolids application, respectively (Cogger et al 1999).…”

Availability of nitrogen from municipal biosolids for dryland forage grass. Can. J. Plant Sci. 80: 575-582. A 3-yr study, initiated in 1996, evaluated the availability of N from applied biosolids for dryland forage grass production under the cool, continental climatic conditions in central British Columbia. Treatments included 600 (LB), 1200 (MB) and 1800 (HB) kg total N ha -1 applied as municipal biosolids, a single application of 150 kg N ha -1 as urea in the first year of the experiment (SF), a multiple application of 150, 60 and 30 kg N ha -1 as urea in the first, second, and third years of the experiment (MF), and a control that received no biosolids or urea. All treatments were roto-tilled to 15-cm depth and seeded to a mixture of four grasses. The LB treatment was predicted to supply a similar quantity of plant-available N as the MF treatment, assuming 25, 10, and 5% of biosolids N is available in the first, second, and third year, respectively. Soil N fertility was poor as indicated by the very low forage yield and N uptake in the control, and minimal apparent net soil N mineralisation. Recovery of urea N in the crop over 3 yr averaged only 27%, likely reflecting net immobilisation in this recently broken site and accumulation of N in non-harvested portions of the crop. Cumulative recovery of N from biosolids in the harvested forage averaged only 11%. However, the fertiliser N equivalency of the biosolids N (ratio of recovery of biosolids N to urea N) was estimated at 41%, close to the predicted value of 40%. Forage yield and N uptake were similar for the LB and MF treatments, suggesting that actual biosolids N availability was similar to that predicted. Limited forage yield increase for the HB compared with the MB treatment early in the experiment, and high forage nitrate content for the HB treatment in the first year, suggest that the HB treatment initially supplied an excessive quantity of N. Both urea and biosolids applications increased cumulative uptake of other macro-and micro-nutrients, with forage Cu concentrations reaching values in the establishment year that may be of concern for some animal species. Monitoring of forage NO 3 and Cu concentrations is advisable where biosolids are applied.

“…Although the effects of poultry litter have received little attention, several researchers have reported increased concentrations of trace metals in the herbage of tall fescue in response to sewage sludge applications (Boswell, 1975; King, 1981; Kiemnec et al. , 1987; Alberici et al.…”

Poultry litter is commonly applied to pastures as an organic fertilizer. However, poultry litter also typically contains numerous heavy metals that may accumulate in soil and can pose an environmental threat when it is applied to pastures. The objective was to ascertain uptake characteristics of heavy metals by tall fescue (Festuca arundinacea Schreb.) from soil with a history of poultry litter additions as affected by subsequent applications of poultry litter. Poultry litter was applied to small plots at rates of 0, 2AE2 and 4AE5 t dry litter ha )1 . In the 7AE5 months following application of litter, cumulative dry-matter (DM) production of herbage was higher (P < 0AE05) in the plots that received poultry litter compared with the control plots where no litter was applied. However, concentrations of Al, Cu, Fe, Mg, Mn, Se and Zn in herbage were unaffected by the rate of application of poultry litter. All metal tissue concentrations, except for Fe, were affected by sampling date. While tall fescue responds to poultry litter with increased DM production, it does not appear to accumulate excessive quantities of micronutrients associated with the application of poultry litter.

“…Nitrogen management is a key concern because N accumulated from previous biosolids applications can have a significant effect on N requirements for subsequent crops (Sullivan et al, 1997; Kiemnec et al, 1987). Accumulation of excess P is a water quality concern on sites receiving repeated applications of animal manure (Sharpley et al, 1994), and biosolids may pose P concerns similar to those for manure (Maguire et al, 2000).…”

Seven Years of Biosolids versus Inorganic Nitrogen Applications to Tall Fescue

Repeated applications of municipal wastewater biosolids is cost effective for biosolids managers, but may lead to undesirable accumulations of nutrients or contaminants. We evaluated the effects of seven years of biosolids applications on tall fescue (Festuca arundinacea Schreb.) production and nutrient availability. We compared two types of Class A biosolids applied to tall fescue on a sandy loam in western Washington. Mean annual biosolids rates of 290, 580, and 870 kg total N ha(-1) yr(-1) were compared with inorganic N and zero-N controls using a randomized complete block design. We measured yield and N uptake for each forage harvest, plant tissue metals at selected harvests, soil nitrate each fall, diethylenetriaminepentaacetic acid (DTPA)-extractable metals after five years of applications, and soil pH, available P, and organic C after seven years. Forage yields increased with biosolids rate. Apparent nitrogen recovery (ANR) for biosolids averaged 18% in 1993 (Year 1), 35% in 1994, and 46% in 1999. The ANR for inorganic N averaged 62% from 1994-1999. Residual soil nitrate was less than 25 kg ha(-1) for all treatments through 1995, but increased beginning in 1996 for the high biosolids rate. Biosolids increased soil organic C levels by 2 to 5 g kg(-1) and Bray-1 P levels by 300 to 600 mg kg(-1) (0-15 cm depth). Plant tissue Zn increased from 24 to 66 mg kg(-1) at the highest application rate. Nearly all of the DTPA-extractable metals remained in the 0- to 8-cm soil depth.
