“…In studies from Europe, North America, and New Zealand, manure and slurry applications, especially in fall and winter, have been shown to cause large losses of DRP and TP (Niinioja, 1993; Turtola and Kemppainen, 1998; Smith et al, 2001; Withers et al, 2001) and fecal microbes (Nunez‐Delgado et al, 2002; Shima et al, 2002; Tyrrel and Quinton, 2003) to downstream waters. Slurry application, to frozen soils in particular, was found to increase nutrient runoff to waters after snow melt in Finland (Niinioja, 1993; Turtola and Kemppainen, 1998).…”

The recent growth in the size of dairy cattle farms and the concentration of farms into smaller areas in Finland may increase local water pollution due to increased manure production and slurry application to grass. Therefore, a field study was conducted to monitor losses of total phosphorus (TP), dissolved reactive phosphorus (DRP), and fecal microorganisms in surface runoff from a perennial ley. Cattle slurry was added once a year in June 1996-1997 (Study I) and biannually in June and October 1998-2000 (Study II). The slurry was surface broadcast or injected into the clay soil. The field had a slope of 0.9 to 1.7%. Mineral fertilizer was applied on control plots. Biannual slurry broadcasting increased DRP (p < 0.001) and TP losses (p < 0.001) and numbers of fecal microorganisms in surface runoff waters. The highest losses of TP (2.7 kg ha(-1) yr(-1)) and DRP (2.2 kg ha(-1) yr(-1)) and the highest numbers of fecal coliforms (880 colony-forming units [CFU] per 100 mL) and somatic coliphages (2700 plaque-forming units [PFU] per 100 mL) were measured after broadcasting slurry to wet soil followed by rainfall in fall 1998. Injection reduced the TP and DRP losses in surface runoff by 79 and 86%, respectively, compared with broadcasting (17 Oct. 1998-27 Oct. 1999). Corresponding numbers for fecal coliforms were 350 CFU (100 mL)(-1) and for somatic coliphages were 110 PFU (100 mL)(-1) in surface runoff after injection in October 1998. Slurry injection should be favored when spreading slurry amendments to grassland to avoid losses of P and fecal microorganisms in runoff to surface waters.

“…Just for comparison, dealing with diluted feces spread as slurry fertilizer, and just counting fecal bacteria (not viruses) Núñez-Delgado et al (2002) detected a prolonged persistence of viable fecal microorganisms in runoff samples generated in a pastureland. Also, fecal bacteria remained viable in leachates after passing through 70 cm of soil in column experiments ( Núñez-Delgado et al, 1996 ) and through up to 90 cm of soil in field experiments ( López-Periago et al, 2002 ).…”

Some environmental aspects are being increasingly studied in relation to the COVID-19 pandemic. Specifically, studies focusing on wastewater could be used for early warning, based on wastewater based epidemiology precepts. However, sewage sludge has been poorly studied in this regard up to now. In addition, soils have not been considered in publications related to SARS-CoV-2. In this piece, some comments are included to suggest a discussion regarding the eventual convenience of considering future studies focusing on soils receiving the spreading of wastewater and sewage sludge, as well as on plants growing on them.
