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.

Hau Giang province
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:: 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.

Tytuł:: Micromycetes Communities of Soil Fungi Occurring in the Buffer Zones of Selected Agricultural Catchment

Tematy:: micromycetes fungi

Opis:: The studies of micromycetes fungi and physicochemical properties were carried out on the soils of buffer zones of a small watercourse in the agricultural landscape of north-eastern Poland. One of the zones was under a tree which was adjacent to the arable soil, the other one was under a turf located near the grassland. It turned out that the character of vegetation and the way the land was used had an influence on the analyzed soil parameters. Soil under trees was characterized by more diversified structures of fungi communities, it also produced more carbon dioxide and nitrous oxide than soil under turf. This allows us to state that tree-lined buffer zones are more effective in preventing surface water pollution by biogenic compounds displaced from agricultural land compared to the buffer zone under the grassing.

Tytuł:: Soils of Buffer Zones as a Source of Nitrogen Compounds
Autorzy:: Krasowska, Małgorzata
Powiązania:: https://bibliotekanauki.pl/articles/123243.pdf

Wydawca:: Polskie Towarzystwo Inżynierii Ekologicznej
Tematy:: buffer zone

Opis:: A buffer zone is a belt of shelter or permanent grassland separating the agricultural land from watercourses and water reservoirs. According to the Code of Good Agricultural Practices, they constitute a landscape element that can limit the migration of biogenic substances. Increasing attention is paid to the fact that these barriers are effective during the growing season. However, in the autumn-winter and early-spring half-year, they can be a source of nitrogen compounds leached from the catchment to the surface water. In connection with this, research was undertaken to assess the content of nitrogen compounds in the soil of the zone at the channel and water of the watercourse in a small agricultural catchment. The processes occurring in the buffer zones leading to the release of biogenic compounds do not only concern leaching them to surface and groundwater; therefore, the amount of nitrous oxide emissions, which is the result of the denitrification process occurring in the soil, was examined. On the basis of the obtained results, it was found that an increased content of nitrogen compounds in the soil of buffer zones may have an impact on the elevated emission of N₂O and a raised content of these substances in surface water.

Opis:: The influence of different agriculture systems and measures of basic tillage on nutrient regime, its relation to the number of microorganisms involved in transformation of organic matter in typical black soils was studied. Direction of the formation processes of some physiological indices in the field of wheat winter was investigated. It was found that the most favorable conditions of nutrition and soil microflora development, as well as indices of crop growth and development are created when using ecological system of agriculture.
