“…Page et al ( 2014 ) claim that soil reaction cannot be treated as a sole indicator of the mobility of heavy metals and their availability to plants, or the risk of their migration to the water environment. Tahervand and Jalali ( 2016 ) demonstrated that sorption and desorption of heavy metals in soil depended not only on the soil’s pH but also on its content of organic matter and calcium carbonate and on the chemical properties of a given metal. Cd and Ni are most strongly adsorbed in soil with a high content of organic matter, while Fe in soil rich in CaCO 3 .…”

Field trials were conducted in 2004–2015, in Bałcyny, on haplic Luvisol formed out of light boulder clay. The experiment consisted of the following treatments: control (no fertilization), NPK, manure (FYM), dried pelleted sewage sludge (DPSS), composted sewage sludge (CSS), compost made from municipal sewage sludge and straw (SSCS), compost Dano made from unsorted household waste (CUHW), and compost produced from urban green waste (CUGW). Over a period of 12 years, 30 t DM/ha of each manure and composts were used, that is, 10 t DM/ha in each rotation of a crop rotation sequence. Nitrogen fertilization was kept on the same level on all experimental plots. Soil samples from the 0- to 20-cm horizon were collected after the third rotation crop, which was winter wheat harvested in 2015. It has been demonstrated that CUHW raised the soil total Cu content the highest, while the soil content of Zn was elevated the most by DPSS. The content of the remaining heavy metals (Pb, Ni, Cr, Mn, and Fe) increased as well, but to a lesser extent. The soil abundance of phytoavailable forms of copper improved even greater (from 75% when fertilized with CUGW or CSS, up to 124% when treated with CUHW). Soil content of soluble forms of such metals as Zn, Pb, Cr, Mn, and Fe changed less. The content of all analyzed heavy metals in soil (a form approximating the total content) was significantly positively correlated with the content of organic carbon (C-org.). This is the evidence for stronger adsorption of the above elements in soil richer in organic matter. On the other hand, the content of available forms of heavy metals depended more on the soil pH than on its content of C-org.

“…Similarly, Cr levels were below the limits reported by Oliveira [33], who observed concentrations between 5 and 100 mg g −1 to be toxic for ryegrass. In turn, Cd contents were below the quantifiable limits of the methodology, a result that could be due to the low solubility of this metal at neutral and basic pH [34].…”

Wood ash produced through cellulose manufacturing has agricultural uses due to its neutralizing power, like that of commercial products, in addition to providing key soil nutrients such as Ca, Mg, K, and P. However, this industrial waste can possess heavy metal(oid)s that bioaccumulate in the food chain. The objective of this study was to determine the effect of wood ash (WA) on the physicochemical properties of an Ultisol, the mobility of heavy metal(oid)s (As, Cd, Cr, Pb, and Ni) in the soil-plant-water system, and the nutritional response (N, P, and K) of ryegrass (Lolium perenne L.). The experiment was conducted in pots, under greenhouse conditions, using a completely randomized design. Ryegrass was grown in pots containing mixtures of WA plus soil at 7.5, 15, 30, and 75 g kg−1, commercial lime plus soil at 1.5 g kg−1, and unamended soil as a control. Heavy metal(oid)s were analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES). All WA doses favored an increase in pH and the availability of P, Ca, Mg, Na, K, Cu, and Zn in soil and N, P, and K absorption in ryegrass. WA favored the availability and later absorption of heavy metal(oid)s by ryegrass (staying mainly in the roots). Heavy metal(oid)s mobility in the soil-plant-water system was as follows: Cr > Pb > Ni > As.

“…The desorption amount was often used as an index to indicate the adsorption strength, and can generally be used to illustrate the bonding degree of the colloidal surface active adsorption position with heavy metal ions (Tahervand et al, 2016(Tahervand et al, , 2017. The desorption isotherm and desorption rate of Ni on bottom sediment and soil are shown in Figure 3.…”

The test adopted the OECD (Organisation for Economic Co-operation and Development) guideine106 equilibrium adsorption method (Bian et al., 2016), to explore the Ni adsorption behavior of the bottom sediment and black soil of the lake. The isothermal adsorption curve of Ni on sediment and black soil retained an "S" shape, and the Freundlich model and D-R model could sufficiently fit the adsorption of Ni by sediment and soil, and the correlation coefficient r was 0.9859~0.9963; Within 120 min, the adsorption amount of nickel in the sediment and soil reached 99.57% and 99.84% of the total adsorption amount, respectively, and reached equilibrium after 720 min. The final desorption amounts of Ni in sediments and soil accounting for 1.26% and 1.35% of the adsorption amounts, respectively. The amount of Ni adsorbed in the sediment increases with rising temperature, and the adsorption coefficient changes in the following manner: Kf 15 °C < Kf 25 °C < Kf 35 °C, Δ G < 0. The adsorption process of nickel on sediment and soil is spontaneous and high temperature is beneficial to this process. The removal of organic matter from sediment and soil weakened the adsorption of nickel, indicating that organic matter could improve the interception of nickel.
