“…Under the same groundwater level in this study, the variations in Ca 2+ , Mg 2+ and SO 4 2- were basically equivalent, yet their rates of variation was not as drastic as those of Na + and Cl - . The correlation analysis of the ions also suggested that Ca 2+ and Mg 2+ were most strongly related, and they are usually grouped into the same category in studies of ion transport [39,43]. Due to the effects of ionic charge, hydration radius, ion concentration, and other characteristics, Ca 2+ , Mg 2+ , and SO 4 2- had a strong capacity to be absorbed by soil colloids and were minimally influenced by the movement of irrigation water.…”

The groundwater level is the main factor affecting the distribution of soil salinity and vegetation in the Yellow River Delta (YRD), China, but the response relationship between the spatial distribution of soil salt ions and the groundwater level in the soil- Tamarix chinensis system remains unclear. In order to investigate the patterns of soil salt ions responding to groundwater levels, in the ‘groundwater-soil- T . chinensis ’ system. Soil columns planted with T . chinensis , a constructive species in the YRD, were taken as the study object, and six groundwater levels (0.3, 0.6, 0.9, 1.2, 1.5 and 1.8 m) were simulated under saline mineralization. The results demonstrated the following: As affected by groundwater, Na + and Cl - were the main ions in the T . chinensis -planted soil column, with a trend of decreasing first and then increasing by the increase of soil depth. However, the contents of K + and NO 3 - gradually decreased and CO 3 2- +HCO 3 - gradually increased. As affected by groundwater evaporation, all the salt ions except CO 3 2- +HCO 3 - exhibited different degrees of surface aggregation in the 0–20 cm layer. However, due to the impact of root uptake, the contents of the salt ions rapidly decreased in the root distribution layer (20–50 cm soil layer), which rendered a turning-point layer that was significantly lower than the surface soil layer; such decreases in ion contents showed a relatively large rate of variation. In the whole T . chinensis -planted soil column, with increasing groundwater level, the contents of Na + , Cl - , Ca 2+ , Mg 2+ , and NO 3 - all tended to first decrease, then increase and decrease again, but the content of CO 3 2- +HCO 3 - first decreased and then increased. Therefore, the 0.9 m groundwater level was the turning point at which the main salt ions underwent significant changes. The contents of Na + , Cl - , Ca 2+ and Mg 2+ in the T . chinensis planted soil column exhibited moderate variability (14.46%111.36%) at most groundwater level except less than 0.9 m. The...

“…188/2003 indicates the value of the amount of SSL that can be applied into the soil, whereby the permitted amount of SSL applied shall not exceed 15 tons of dry matter per 1 ha over a period of five years. In many studies, the application of SSL in agriculture is studied and evaluated mainly from the point of view of SSL utilization as a source of important macro-and microelements for plant nutrition, plant production, risks of pathogens transfer present in the SSL, and translocation of toxic elements or xenobiotics to the soils and plants (Bettiol and Ghini 2011;Marguí et al 2016;Mossa et al 2017;Borba et al 2018). The availability and mobility of macro-and microelements or toxic metals in the systems SSL/soil have been examined in short-term laboratory studies using both leaching columns and incubation (Toribio and Romanyà 2006), lysimeters (Borba et al 2018), and under conditions of experimental fields (Wolejko et al 2013).…”

The aim of the work was to characterize the samples of sewage sludge (SSL) originated from the Wastewater Treatment Plant Piešťany (TAVOS, a.s., Trnava, Slovakia) in terms of their potential application into the soils. Within the physico-chemical characterization of SSL, the samples were analysed in terms of the values of pH, cation exchange capacity (CEC), total organic carbon (TOC), water holding capacity (WHC), as well as the presence of heavy metals. It was found that SSL contained significant amounts of microelements Zn (1,269 mg.kg-1, d.w.) and Cu (224 mg.kg-1, d.w.). Laboratory lysimeter experiments involving the application of SSL into the top layer of agriculturally used soil (0 – 10 cm) forming a soil column, in which seedlings of tobacco (Nicotiana tabacum L.) were cultivated, showed that in the case of SSL application in the highest permitted amounts (15 t.ha-1) only 0.11 % Zn and 0.07 % Cu were released into the soil eluate during a 28 day of exposure, while in tobacco plants 0.13 % Zn and 0.05 % Cu were accumulated from the total amount of Zn and Cu originated from the application of SSL (Zn – 133 mg and Cu – 23.5 mg). When applying SSL in amount 30 t.ha-1 i.e., in the dose exceeding the permitted limits, only 0.02 % Zn and 0.04 % Cu were released into the soil eluate and 0.16 % Zn and 0.09 % Cu were accumulated in tobacco plants from the applied amount of SSL (Zn – 267 mg and Cu – 47.0 mg).

“…The effects of different soil management practices on biogeochemical flows need to be monitored and understood [1]. To understand the flow of nutrients at the soil-water interface, studies of the composition of the soil solution consider the processes of entry and exit of ions in each land-use situation [2]. The chemical elements present in the soil solution from the decomposition of leaf litter and the composition of the soil depend on various factors, namely, microbial population, plant species, temperature, groundwater flow, and soil management practices.…”

For sustainable production systems, the nonuse of fire (where there is a greater loss of soil nutrients), would be a solution for the conservation of nutrients in the soil, with the use of management by cutting and grinding, introduction of AFSs (agroforestry systems), and maintenance of riparian vegetation. The concentrations of carbon and nutrients were evaluated in the soil solution in two small hydrographic basins in the municipality of Igarapé-Açu (Pará state) in the eastern Amazon region, Brazil. The evaluations were performed considering the biogeochemical cycling in six land-use classes—riparian forest, secondary forest (capoeira), pasture, slash-and-burn agriculture, chop-and-mulch agriculture, and an agroforestry system (AFS). The objective was to determine the effects of different land-use systems on the composition of the soil solution, aiming to recommend sustainable practices. The concentrations of nutrients were greater in the areas of slash-and-burn agriculture and pasture, indicating greater losses of these nutrients due to runoff and leaching. The loss of nitrate was highest in the slash-and-burn area, while the organic carbon and organic nitrogen losses were greatest in the riparian forest, then in the secondary forest and agroforestry areas.
