“…Moreover, high average Cu concentration for swine slurry was also observed in England (470.00 mg/kg DM; Nicholson et al 2003). Furthermore, in China according to Xu et al (2013), high average Cu concentration in pig manure was reported (418.42 mg/kg); and Yang et al (2017) ranged the Cu concentration in the swine compost samples from 3.55 to 916.0 mg kg À1 DW.…”

“…In general, a wide range of Zn content was observed because many factors can alter the Zn excretion by faeces (the diet, the management, the different regulations). Li et al (2018) reported high average Zn concentration in the solids residue of swine manure (17467.00 mg/kg), and Xu et al (2013) observed a wide range of this element (183.42 to 1126.25 mg/kg) in pig manure in China. According to Yang et al (2017), the range of Zn concentration in the swine compost (containing swine slurry and straw) ranged from 11.80 to 3692.00 mg kg À1 DW in China farms.…”

Animal manure is one of the diffusion routes of heavy metals and metalloids into the environment, where the soil can accumulate them. Heavy metals and metalloids can then be released into groundwater sources, be absorbed by crops, and enter the food chain with negative effects for human and animal health. The aim of this study was to evaluate the concentration of heavy metals and mineral nutrients from modern animal rearing systems in order to develop effective strategies to increase the sustainability. Samples of feed (n ¼ 24: n ¼ 16 from swine, n ¼ 8 from cattle), faeces (n ¼ 120: n ¼ 80 from swine, n ¼ 40 from cattle) and water (n ¼ 8), were collected from eight typical intensive swine and cattle farms located in northern Italy. All samples were analysed for the humidity and the principal components. The samples were also dried, mineralised, and analysed by ICP-MS to detect the following elements: Na,

“…The loadings of nutrients and non‐nutrient metals with RM and SL were calculated for application rates that would most likely be used in crop production. Swine slurry (unseparated RM) and SL are commonly used as a N source at rates of about 100 kg total N ha −1 yr −1 or slightly higher (Meade et al, 2011; Schlegel et al, 2015; Xu et al, 2013). Thus, a comparison of loadings of nutrients and metals using RM at 100 kg total N ha −1 versus SL at an equivalent rate was made.…”

Comparison of Nutrient and Metal Loadings with the Application of Swine Manure Slurries and Their Liquid Separates to Soils

The accumulation of phosphorus (P) and metals is a serious concern with the continuous application of manure to agricultural soils. Solid-liquid separation of swine slurry is a promising approach to reduce P and metal loadings through application of separated liquid (SL) as a nutrient source. However, little information is available on nutrient and metal loadings with the application of SL compared with unseparated raw manure (RM). We analyzed element concentrations and calculated nutrient and metal loadings for RM and their respective SL applications, considering an application rate of 100 kg total nitrogen (N) ha -1. Samples of SL were obtained through three separation techniques: (i) centrifugation without a flocculant, (ii) centrifugation with a flocculant, and (iii) rotary press with a flocculant. Irrespective of separation technique, calculated P loadings with the application of SL were only 50 to 70% of that of RM at equivalent rates of total N yet exceeded crop removal rate. In contrast, calculated K and Na loadings with SL application were significantly greater than with RM, indicating a possible build-up of K and Na in soil. Calculated Ca and Mg loadings were significantly greater with RM than with SL. Loadings of Al, As, Ba, Cd, Cr, Fe, Mn, Ni, Pb, Sn, Se, Ti, and V were low, whereas Cu and Zn loadings were above crop removal rates for RM and SL. For solidliquid separation to provide a lasting solution to the problem of P and metal accumulation, the SL must be supplemented with commercial N fertilizer to meet crop N demand. A pplication of swine slurry to agricultural soils as a nutrient source is a commonly practiced option in recycling livestock manure and in reducing synthetic fertilizer inputs for crop production (Choudhary et al., 1996;Edmeades, 2003;Penha et al., 2015). However, long-term applications of swine manure, which are often based on crop nitrogen (N) requirements in Canada, may result in an accumulation of nutrients other than N and non-nutrient metals in soils, which may lead to crop toxicity and environmental problems (Gräber et al., 2005;Møller et al., 2007;Penha et al., 2015;Schoenau and Davis, 2006). Phosphorus (P) is of particular concern because the build-up of P in soils may increase P losses from soils through runoff and leaching (Allen and Mallarino, 2008;Kumaragamage et al., 2011) to waterways, triggering eutrophication, a process primarily controlled by dissolved P concentrations in freshwater (Schindler, 1977). Because inorganic salts are commonly added to animal feed, manures usually contain high concentrations of salts. An increase in soil salinity with continuous application of manure (Li-Xian et al., 2007;Schlegel et al., 2015) can deteriorate soil quality and negatively affect crop growth, which has been of little concern until recently. Micronutrients such as manganese (Mn), copper (Cu), and zinc (Zn), which are routinely added to livestock feed to fulfill nutritional needs and for the prevention of diseases, are required in small amounts by plants and thus m...

Animal manure may be a primary source of cadmium (Cd) to Chinese farmlands because abnormally high values of Cd were observed in various manures. In this study, we evaluated the potential risk of Cd in soil-plant (maize and soybean) system as a result of the long-term (10 years) application of pig manure (PM). During 10 years, the loading rate of Cd through PM application ranged from 26.33-131.50 g/ha/year, while the crops removal rate of Cd was relatively small in comparison to the quantity of Cd supplied by PM application (1.03-4.36 g/ha/year). The PM application significantly increased total Cd concentration in soil. Although the Cd levels did not exceed the Chinese soil quality criteria (1.0 mg/kg dry matter (DM)), it would only take less than two years to reach this limit at high PM application rate. The same trend was also observed for the Cd concentration in maize and soybean. More seriously, Cd concentration in grain of soybean was higher than the threshold values for animal and human ingestion (0.2 mg/kg DM). Based on a mass balance calculation, we found that atmospheric deposition was also an important source of Cd in the experimental area (10.27 g/ha/year). Moreover, the application of PM enhanced the leaching loss of Cd, but they were still fairly small (0.34-0.73 g/ha/year).
