“…Another explanation is the reduction in soil pH probably due to nitrification of NH 4 -N from the sludge [24]. With regard to the change in the soil pH with the treatment sludge application, the sludge reduced the soil pH value of sludge applied to alkaline or neutral soils reported by researchers [25,26].…”

“…The most sensitive indicators in the physical indicator group were therefore those related to water retention, microporosity, or aggregate stability. These soil properties are well known to be sensitive to changes in soil when SS or other organic amendments are used [3,67], as they represent the changes induced in soil structure as a response to increased inputs of organic matter [68].…”

The aim of this work was to identify the most sensitive soil quality indicators and assess soil quality after long-term application of sewage sludge (SS) and conventional mineral fertilization for rainfed cereal production in a sub-humid Mediterranean calcareous soil. The treatments included six combinations of SS at different doses (40 t ha−1 and 80 ha−1) and frequencies (every 1, 2 and 4 years), plus a control with mineral fertilization, and a baseline control without fertilization. Twenty-five years after the onset of the experiment, 37 pre-selected physical, chemical and biological soil parameters were measured, and a minimum data set was determined. Among these indicators, those significantly affected by treatment and depth were selected as sensitive. A principal component analysis (PCA) was then performed for each studied depth. At 0–15 cm, PCA identified three factors (F1, F2 and F3), and at 15–30 cm, two factors (F4 and F5) that explained 71.5% and 67.4% of the variation, respectively, in the soil parameters. The most sensitive indicators (those with the highest correlation within each factor) were related to nutrients (P and N), organic matter, and trace metals (F1 and F4), microporosity (F2), earthworm activity (F3), and exchangeable cations (F5). Only F3 correlated significantly (and negatively) with yield. From these results, we concluded that soil quality can be affected in opposite directions by SS application, and that a holistic approach is needed to better assess soil functioning under SS fertilization in this type of agrosystem.

“…A 0.05g sample of dried soil from each depth of each site was accurately weighed and placed in a Teflon microwave vessel and then digested with a solution of 5 parts concentrated HNO3 to one part 70% HClO4 (v/v) at temperatures between 90°C and 150 °C on an electric heating plate (Zuo, et al 2019). The liquid prepared by the digested solutions was then diluted to 25 mL with deionised water.…”

“…Most of the plants have spontaneous potentiality to absorb varied and large amounts of bioavailable forms of trace elements (Luo, et al 2019). The high rate of transpiration could lead to the absorption of trace elements from soil and transfer elements to shoot and grain (Abbas, et al 2017;Zhou, et al 2019;Zuo, et al 2019). Micronutrient trace elements including Cu, Co, Fe, Mo, Zn, Ni, and Mn are essential for plant growth, but…”

Pollution resulting from toxic trace elements is an increasing concern around the world especially in developing countries such as China. Rapid industrialisation, urbanisation and agricultural development are the dominant sources of anthropogenic contamination contributing to an increased potential toxicity of trace elements in the irrigation water-soil-food chain. Xin Jiang of China is a reserved cultivated land development area that could provide the most extensive strategic support for food production and arable land security in China. Thus, it is crucial to investigate the bioaccumulation and translocation of trace elements in order to assess the ecological and human health risks in the traditional oasis system of the agricultural areas in Bay Cheng County, Xin Jiang.This study analysed the levels of trace elements in different layers of the soil, the irrigation water and the wheat plants, and the relationships among them. The results indicated that cadmium (Cd) and chromium (Cr) were the primary pollutants in soils and wheats respectively, and they fell into the serious pollution category. However, no trace elements over the pollution limits were detected in irrigation water. The maximum values of trace elements appeared in the soil layers at 5-10 cm and 10-15 cm. The second pollution levels of trace elements in the soil layers were found at 0-5 cm and 0-20 cm, which were higher than those at 20-80 cm. In wheat a high amounts of absorption for Se, Cr, Zn and Cu, but low for Pb were detected in different parts of the plant. The roots of wheats were more eco-toxic to Cd, Co and Pb than other tissues, indicating that roots were more effective at absorbing Cd, Co and Pb, as these metals are usually toxic in the soil. Se, Cu and Zn showed a higher ability of being transferred from soils to the edible parts of crops. The bio-transfer factors of Zn, Mo, Cu, Mg and Mn were considerably higher than those of other elements. The average cancer risk of As, Cd, Co, Ni and TCR in wheat grains exceeded the safety reference limit 3
