Opis:
The aim of this study was to assess the impact of the reuse of purified wastewater from the wastewater treatment plant in the city of Settat on the physicochemical quality of agricultural soils compared to the agricultural soils irrigated by rainwater in the region of Chaouia in Morocco. The results obtained showed that despite the great fertilizing value of the purified wastewater, a slight increase in salinity was noted; they also reveal a significant difference in pH. The accumulation of sodium, total limestone and active limestone in the soil increased significantly in the soils irrigated by treated wastewater; in contrast, calcium increased significantly in the soils irrigated by rainwater.No significant differences were recorded for humidity, electrical conductivity, ammonium, nitrates, phosphorus, potassium, organic matter, total nitrogen or cation exchange capacity.

Opis:
Microplastic (MP, 1 μm − 5 mm) pollution has become a global environmental concern with potential risk to ecosystem and human health. Information on the accumulation of MPs in aquatic species has been well documented, while information on the uptake and accumulation of MPs by higher plants is still very scarce. Terrestrial edible plants are directly exposed to MPs when soil was applied with sludge, organic fertilizer, plastic mulching, waste water irrigation, plastic littering, surface runoff or from atmospheric deposition of airborne MP. One study using fluorescent marker recently showed that plant can accumulate MP through uptake from MP polluted soil. Thus, potentially contaminating the base of the food-web and also indicating new exposure route to MP ingestion. This review present a discuss of the implication of these findings to human, who may be ingesting an estimated 80 g of MP through eating of plant daily as global consumption rate of plant continually increase. Also, benefit for the terrestrial ecosystem is discussed, by which plant acts as a potential remediator of MP polluted soil either by phytoextraction, phytostabilization and phytofilteration. We conclude by pointing knowledge gap and suggesting key future areas of research for scientists and policymakers.

Opis:
The study aimed to evaluate the occurrence of some heavy metals in agricultural soil in the Hau Giang province, Vietnam. The geographical accumulation index (Igeo), pollutant load index (PLI) and ecological risk index (RI) are used to assess the pollution levels and potential ecological risks due to the presence of heavy metals in agricultural soil. The results showed that the mean concentrations of Cu, Pb and Zn in the soil ranged from 16.25–40.32, 18.05–29.92 and 52.78–147.22 mg/kg, respectively, within the limits of QCVN 03-MT:2015/BTNMT. Cluster analysis showed that Pb originated from the process of using fertilizers, especially phosphate fertilizers in farming. Cu and Zn possibly share a common origin from the use of pesticides and fungicides in agricultural production. The Igeo value of Cu, Pb and Zn gradually increases in the order of Cu < Zn < Pb. The PLI (1.03–1.97) reflected that the soil in the study area is moderately polluted. The RI (14.80–25.33) represented a low potential ecological risk. In particular, position D3 had the highest level of pollution and risk among the study sites. Pb had the highest level of accumulation in soil with the highest single ecological risk factor; thus, measures should be taken to limit the source of Pb generation. The results of the study also indicated that ingestion route is the main exposure pathway by which heavy metals can be harmful to humans.

Opis:
Erosion processes can strongly influence the dissipation of glyphosate and aminomethylphosphonic acid applied with Roundup Max in agricultural soils; in addition, the soil structure state shortly before erosive precipitations fall can be a key parameter for the distribution of glyphosate and its metabolite. Field rain simulation experiments showed that severe erosion processes immediately after application of Roundup Max can lead to serious unexpected glyphosate loss even in soils with a high presumed adsorption like the Cambisols, if their structure is unfavourable. In one of the no-tillage-plot of the Cambisol, up to 47% of the applied glyphosate amount was dissipated with surface run-off. Moreover, at the Chernozem site with high erosion risk and lower adsorption potential, glyphosate could be found in collected percolation water transported far outside the 2x2 m experimental plots. Traces of glyphosate were found also outside the treated agricultural fields.

Opis:
Selected monitoring properties of agricultural soil from the Imielin experimental site. The effects of two types of agricultural practice: variable rate application (VRA) and uniform (UNI) N dose on selected chemical properties of soil were compared in a fi eld fertilization experiment. Nitrogen, in doses 60 or 80 kg·haˉ¹ (UNI) and 55–105 kg·haˉ¹ (VRA), was applied to soil farmed with winter wheat (Triticum aestivum L.). The research was conducted in the 2012/2013 growing season in Poland on 22 ha of production fi elds located in the Imielin countryside (central Poland). The soil samples were taken from three depths: 0.0–0.3, 0.3–0.6, and 0.6–0.9 m, and the pH, HAC, TEB, CEC, and BS were determined. The application of the nitrogen fertilizer in the two types of agricultural practice – variable rate application (VRA) and uniform (UNI) N dose modified the basic physical and chemical properties of soil. The highest values of pH and hydrolytic acidity were observed at the soil depth of 0.6–0.9 m after the first rate of nitrogen fertilizer was applied. Cation exchange capacity of soils collected after uniform nitrogen rates were characterized by values decreasing with the increasing depth of the soil profile.
Wybrane parametry monitoringowe gleb rolnych obiektu doświadczalnego Imielin. Wpływ dwóch rodzajów nawożenia: zmienną (VRA) i stałą dawką azotu (UNI) na wybrane właściwości chemiczne gleb została określona na podstawie doświadczeń polowych. Dawki azotu w ilościach 60 i 80 kg·haˉ¹ (UNI) oraz 55–105 kg·haˉ¹ (VRA) były dodawane do gleby, na której uprawiano pszenicę ozimą (Triticum aestivum L.). Badania przeprowadzono w sezonie wegetacyjnym 2012/2013 na 22 ha polu uprawnym zlokalizowanym w miejscowości Imielin (centralna Polska). Próbki gleb pobrano z trzech głębokości: 0,0–0,3, 0,3–0,6 i 0,6–0,9 m, i oznaczono w nich: pH, EC, Hh, S, T, V. Aplikacja nawozów azotowych w zmiennej (VRA) i stałej dawce (UNI) azotu modyfikowała podstawowe fizyko-chemiczne właściwości gleby. Największymi wartościami pH i kwasowości hydrolitycznej charakteryzowała się gleba pochodząca z głębokości pomiarowej 0,6–0,9 m, pobrana po pierwszej dawce wysiewu nawozów. Kationowa pojemność gleb pochodzących z poboru po drugiej dawce nawożenia stałą dawką azotu charakteryzowała się wzrostem swej wartości w miarę zwiększania się głębokości pomiarowej.

Opis:
Enzyme activities in soils are influenced by soil characteristics and pollutants and could be indicator of soil quality. This study was undertaken to determine the relationship between physicochemical characteristics, heavy metals contents and enzyme activities (EA) in agricultural soils in the Saiss plain (Morocco). The analysis of six agricultural soil samples (sites 1–6), collected from urban and periurban agricultural soils of Fez region, showed that soils are generally alkaline with high CaCO3 that rich 46%, EC (525–703 μS/cm), rich in organic matter (3.14–5.80%). The Cr, Cu, Ni, Pb and Zn concentrations in the studied area are generally greater than the Upper Continental Crust, with a deceasing order: Zn> Cr> Pb> Cu> Ni. Geo-accumulation index showed that soils are unpolluted to moderately polluted except site 5 and site 6 that are moderately to strongly polluted by respectively Cu, Pb, Zn and Pb. Potential ecological rіsk factors were below 40, which means low potential ecological rіsk except site 5 that has moderate potential ecological risk by Cu and Pb. Soil potential ecological risk indices were found <150 indicating low ecological risk. According to this index, Cu caused more serious pollution than the other elements. The enzyme actіvities of the sіx soil samples showed almost the similar ranges of values. These EA showed the highest values in site 5.The sensіtivity of soil enzyme to heavy metals were observed UREA>PHOS>GALA. Pearson’s correlation showed significant posіtive correlatіon between studied soil EA and between these EA and heavy metals (Cu, Pb and Zn), and significant negative correlatіon between EA and heavy metals (Cr and Ni). The results of this study enrich and provide data base of the impact of heavy metals on soil enzyme actіvities in agrіcultural soils in the Saiss plain.

Opis:
The aim of the study has been to define the stocks and the basic properties of soil organic matter in agricultural-used soil sequence located in the former shoreline of disappearing lakes. The study area is located in the catchment of the Sumowskie Lakes, the Brodnica Lake District, North-Eastern Poland. The investigations involved preparation of five soil pits located in the south-western part of the former Sumowskie Lake bottom and on the southern slope of the adjacent kame hill. The greatest soil transformation is reflected in the quality and quantity of the soil organic matter. Indexes of organic matter quality and TOC stocks are significantly changing along the studied transect. The strongly humidified organic matter is found in mursh horizons. Gyttja layers above the groundwater level have a medium humification index. Horizons saturated with water are very low humidified. TOC stocks drop along the analysed soil sequence from the biogenic plain to the top of the kame hill.
Celem badań było określenie zasobów i podstawowych właściwości materii organicznej sekwencji rolniczo użytkowanych gleb dawnej strefy brzegowej zanikających jezior. Obszar badań był zlokalizowany w zlewni jezior Sumowskich na Pojezierzu Brodnickim w Polsce północno-wschodniej. Analizowano transekt składający się z pięciu profili glebowych znajdujących się w pd.-zach. części dawnego Jeziora Sumowskiego. Obejmował on dno dawnego jeziora oraz przylegające wzgórze kemowe. Największe zróżnicowanie gleb dotyczyło ilości i jakości glebowej materii organicznej. Zarówno właściwości materii organicznej, jak i jej zasoby wyraźnie różnicują się w analizowanym transekcie. Materia organiczna poziomów murszowych gleb pojeziornych odznacza się najwyższym stopniem humifikacji, warstwy gytii, powyżej poziomu wód gruntowych, pośrednim, a poziomy nasycone wodą najniższym spośród analizowanych. Zasoby węgla organicznego zmniejszają się wzdłuż transektu od gleb pojeziornych do szczytu pagórka kemowego (pararędziny).

Opis:
The paper characterises total concentrations of Cd, Cu, Ni, Pb, Zn in the surface layers (0-20 cm) of agricultural soils in Poland (48620 soils samples) and Lublin region (3829 soil samples). The results for Lublin region are expressed in terms of the degree of metal pollution as compared to contamination in the rest of the country. The average concentration of Cd, Cu, Ni, Pb and Zn (in mg kg-1 of soil) in the A horizon of agricultural soils in Poland and in Lublin region (values in parenthesis) are as follows: 0.21 (0.17); 6.5 (4.9); 6.2 (6.6); 13.6 (10.7); 32.4 (23.3). About 79% of the agricultural soils in Poland are characterised by a natural (0°) content of heavy metals while 17.6% contain elevated level (10) of these metals. In the Lublin region it is 91.9% and 6.7%, respectively. About 3% of the Polish soils (1.4% in the Lublin region) exhibit various degrees of contamination with heavy metals. This includes heavy (IV0) and very heavy pollution (V0) which is found in up to 0.4% of the agricultural land and up to 0.2% in the Lublin region.
