The current investigation was undertaken to explore the physico-biochemical properties of sewage sludge (SS) and its feasible application in agricultural field as an organic manure as source of nutrients with to solve the environmental concern. Sewage sludge samples were collected from sewage treatment plants (STP), Bhagwanpur, Varanasi, Uttar Pradesh, India and passed through a 2 mm sieve for further analysis of different physical, chemical and biological parameters. The treated sewage sludge consists of both major and micro nutrients along with a good amount of organic matter. Application of this sewage sludge has the ability to enhance the physical, chemical and biological properties of soil which is beneficial for plant growth and development sustainable soil environment. However, it also contains some amount of toxic heavy metals and organic pollutants that can adversely affect soil environment depending on the origin source of sewage sludge, and treatment process of sewage sludge. Furthermore, the toxic elements go through the food chain due to its uptake and accumulation by crops posing a possible threat to human health. Sewage sludge application in soil offers essential nutrients particularly for plant growth, maintains the organic carbon in soil and decreases environmental concern with economic factors that restrict landfill or incineration disposal of sewage sludge. However, a careful assessment of the characteristics of sewage sludge is required prior to its soil application to improve the soil health without causing environmental hazard. The SS analyzed in the present study had heavy metals content but was within permissible limits as resulted its suitable for soil application as source of nutrients.

The role of human excretion, drinking water, and deposition as a source of heavy metals to municipal sewage was investigated and compared with common levels in sludge for soil application. These sources contributed more than half of the copper (Cu), zinc (Zn), and lead (Pb) content of municipal sewage sludge for soil application, while other sources dominated the fluxes of chromium (Cr) and cadmium (Cd). Drinking water was an important source for Cu and Zn. Deposition contributed about 40% to the Pb flux. Faecal excretion commonly caused less than 10% of the heavy metal load, while urinary excretion was here a negligible heavy metal source.

Проведено исследование эффективности применения разных доз многокомпонентных почвогрунтов на основе осадков сточных (ОСВ) вод кожевенного производства на агрохимические показатели слабогумусированной супесчаной дерново-подзолистой почвы при проведении культуртехнических работ перед озеленением. Цель исследований – изучение действия и последействия почвогрунтов на агрохимические показатели супесчаной дерново-подзолистой почвы в травостое райграса однолетнего сорта «Изорский». Эффективность оценивали на протяжении четырех лет в полевых условиях на опытном полигоне ФГБНУ ВНИИОУ в двух опытах – мелкоделяночном (опыт 1) и вегетационно-полевом (опыт 2). Изучаемые дозы внесения почвогрунтов: 60 тонн на гектар в расчете на 50 %-ю влажность (опыт 1); полное замещение почвогрунтом растительного слоя 0-20 см (опыт 2). Исследование химического состава почвогрунтов и почвенных проб проводили общепринятыми методами комплексного химического анализа; статистическую достоверность результатов определяли методом дисперсионного анализа. Результаты проведенных исследований показали, что наиболее эффективным культуртехническим приемом повышения плодородия слабогумусированной супесчаной дерново-подзолистой почвы на озеленяемых территориях является полное замещение растительного слоя готовым почвогрунтом на глубину пахотного слоя (0-20 см). Положительное влияние обусловлено кислотно-основными свойствами почвогрунтов, а также фактором разложения основной массы под действием почвенного биоценоза, разрушением органоминеральных комплексов в их составе, высвобождением катионов кальция и магния. Данный прием обеспечивает снижение обменной кислотности в почве на 26-32 %, увеличение суммы обменных оснований кальция и магния на 191-246 %, органического вещества – на 97-140 %, содержания подвижных фосфора и калия более чем на 100 %. Эффект проявляется в первый год внесения почвогрунтов. Последействие сохраняется до 4 лет. Оптимальные значения агрохимических показателей дерново-подзолистой почвы достигаются при включении в состав почвогрунта смеси компоста на основе ОСВ кожевенного производства и растительного грунта. The research presents studying the effi ciency of the use of different doses of multicomponent soils based on sewage sludge from leather industry of three options for the agrochemical indicators of slightly humifi ed sandy loamy sod-podzolic soil during agricultural work before landscaping. Effi ciency was evaluated over four years in the fi eld at the experimental training ground of FSBRI VNIIOU in two experiments: a small-plot one (experiment 1) and a fi eld-vegetation one (experiment 2). The studied doses of soil application were 60 tons per hectare per 50% moisture content (experiment 1), full substitution of 0-20 cm of soil layer in the vegetation layer (experiment 2). Studies of the chemical composition of soil and soil samples were carried out by the generally accepted methods of complex chemical analysis. The statistical reliability of the results was determined by dispersion analysis. The results of the studies showed that the most effective cultural technique for increasing the fertility of slightly humus sandy loamy sod-podzolic soil in green areas is the complete replacement of the plant layer with ready-made soil to the depth of the arable layer (0-20 cm). The positive effect was due to the acid-base properties of soil, as well as the factor of decomposition of the bulk under the infl uence of soil biocenosis, the destruction of organic mineral complexes in their composition, the release of calcium and magnesium cations. This technique provided a decrease in metabolic acidity in the soil by 26-32%, an increase in the sum of the exchange bases of calcium and magnesium by 191-246%, organic matter by 97-140%, and the content of mobile phosphorus and potassium by more than 100%. The effect was manifested in the 1st year of soil application. The effect lasted up to 4 years. The most optimal values of agrochemical indicators of sod-podzolic soil were achieved when a compost mixture based on sewage sludge from leather industry and plant soil was included in the soil composition.
