“…Adverse effects of wastes on soil fertility attributes are associated with a sharp increase in pH (Mokolobate and Haynes, 2002;Dikinya and Mufwanzala, 2010), which may reach the alkaline range and decrease the availability of some micronutrients. High charges of micronutrients added in soils, especially Zn and Cu, and the addition of K and other chemical elements or pollutants at levels above those considered agronomically safe for agricultural soils are effects that have been reported for some soils successively fertilized with manures (Torri and Corrêa, 2012;Penha et al, 2015). Excessive levels of P in soil and its runoff from sites with intensive poultry activities are other adverse effects observed in fields intensively and continuously fertilized with poultry litter (Harmel et al, 2009).…”

ABSTRACT:The composition of organic waste (OW) and its effect on soil processes may change soil fertility and electrical conductivity (EC). The side effects of waste use in crop fertilization are poorly understood for Brazilian soils. This study examined the effect of the addition of 15 different organic wastes to Oxisols and a Neosol on pH, base saturation, EC, cation exchange capacity (CEC at pH 7), and the availability of Al, macro (P, K, Ca 2+ , Mg 2+ and S) and micronutrients (B, Fe 2+ , Mn 2+ , Cu 2+ and Zn 2+ ). Soil samples (150 g) were treated with chicken, pig, horse, cattle, and quail manures, sewage sludge 1 and 2, eucalyptus sawdust, plant substrate, coconut fiber, pine bark, coffee husk, peat, limed compost, and biochar. Wastes were added considering a fixed amount of C (2 g kg -1), which resulted in waste rates ranging from 2.5 to 25.6 Mg ha -1 . The soil-waste mixtures were incubated for 330 days in laboratory conditions. The waste liming or acidification values were soil-dependent. The use of some manures and compost increased the pH to levels above of those considered adequate for plant growth. The soil EC was slightly increased in the Neosol and in the medium textured Oxisol, but it was sharply changed (from 195 to 394 µS cm -1) by the addition of organic wastes in the clayey Oxisol, although the EC values were below the range considered safe for plant growth. Changes in the soil availability of P, K + , Ca 2+ and Zn 2+ were highly related to the inputs of these nutrients by the wastes, and other factors in soil changed due to waste use. Organic waste use simultaneously affects different soil fertility attributes; thus, in addition to the target nutrient added to the soil, the soil acidity buffering capacity and the waste liming and agronomic value must be taken into account in the waste rate definition.

The release of phosphorus (P) and zinc (Zn) from swine manure compost and from soils applied with swine manure compost can be accelerated by colloidal particles. This study investigated the concentrations and chemical species of P and Zn in waterdispersible colloids (WDCs) collected from swine manure compost by using X-ray absorption fine structure (XAFS) spectroscopy. A filtration and ultracentrifugation process was used to separate and collect WDCs (20-1000 nm) from the bulk swine manure compost (<2 mm). The swine manure compost contained 2.7 g kg -1 WDC, in which P (140 g kg) was highly concentrated and Zn concentrations were greater than in the bulk compost (1.45 g kg -1). Phosphorus K-edge X-ray absorption near-edge structure (XANES) spectroscopy determined the presence of struvite (NH 4 MgPO 4 ·6H 2 O) as a major P species (74%), followed by tricalcium phosphate as a secondary component (26%). In the WDC fraction, struvite was not found, but tricalcium phosphate (56%) occurred as a primary component. Zinc K-edge XAFS spectroscopy determined hopeite [Zn 3 (PO 4 ) 2 ·4H 2 O, 59%] and to a lesser extent smithsonite (ZnCO 3 , 24%) and Zn adsorbed on ferrihydrite (17%). In the WDC fraction, hopeite (44%) and organically bound Zn (35%) were predominant. Our results demonstrate the notable difference in the concentration and chemical species of P and Zn between the WDC and bulk fractions of swine manure compost. Chemical Species of Phosphorus and Zinc in Water-Dispersible Colloids from Swine Manure CompostKosuke Yamamoto and Yohey Hashimoto* A ccumulation of phosphorus (P) and zinc (Zn) is a concern in agricultural soils where intensive and long-term applications of swine manure are practiced (Martinez and Peu, 2000;Penha et al., 2015). The effluence of P and Zn from swine manure and from soil applied with swine manure can be accelerated by colloidal particles (1-1000 nm in accordance to the International Union of Pure and Applied Chemistry definition) (Slomkowski et al., 2011). Hens and Merckx (2001) reported that P associated with colloidal particles accounts for approximately 75% of effluent P from agricultural soils. Karathanasis (1999) reported that Zn mobility in soils increased 5-to 50-fold in the presence of colloidal particles. Regarding the effects of colloidal particles on bioavailability of elements, Montalvo et al. (2015) demonstrated that colloidal particles increased P bioavailability in a study on P uptake flux by wheat, which accelerated five times in the presence of colloidal P than with dissolved P only. Despite the importance of colloidal fractions in transport and bioavailability, studies have mainly focused on P in particulate and dissolved fractions (operationally defined as a <0.45-mm fraction) and thereby have neglected colloidal fractions in environmental samples.Water-dispersible colloids (WDCs) are representative of readily mobile colloids because of the high dispersibility and mobility in the soil solution (de Jonge et al., 2004). Phosphorus concentrations in WDC fractions (5....

“…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).…”

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...
