“…The changes that the lime-stabilized sludge caused to the soil-exchangeable Na, K, Ca and Mg values are given in Table 4 and Fig. 3 The Na, K, Ca and Mg values increased as the before sowing and after harvest averages, depending on the increased application Sludges contain N and P as well as more or less K, Ca, Mg and Na plant nutrients [41,42]. It should be noted that in the course of application to the soil, the amount of these elements, together with the application, was given to the soil and does not disturb the nutrient balance in the soil.…”

“…Chemical and mineralogical characterizations of the sludge were performed in a laboratory based on SEM/EDX analysis. The chemical analysis of the sludge was based on the following methods: determination of the pH by the method SR EN The types of sludge that were studied had the following characteristics: specific density, rs = 1.65-1.85 g/cm 3 ; density, r = 1.05-1.12 g/cm 3 ; upper limit of plasticity, wL = 100-333%; lower limit of plasticity, wP = 42-218%; linear contraction, 11%, free swelling, 1. The treatment of soil samples that were collected for the tests was in accordance with the standard SR ISO 11464/1998: soil quality, samples pre-treatment for physical-chemical tests.…”

Sludge management is a complex issue due to the environmental standards. It is required that the wastewater treatment activity be in close connection with the controlled recovery and storage of sludge. Thus, by using sludge in agriculture, nutrients essential for plant development can be recycled and some soil properties can be improved. The purpose of this paper was to present some results on the influence of municipal sludge treated and processed in a Euphore plant on the quantity and quality of rapeseed and soybean production. This technology allows for the recovery of the constituents of phosphorus, nitrogen, potassium, sulfur, magnesium, calcium, manganese, zinc, and copper. Our experimental data revealed that the obtained yield of Pioneer PT225 rapeseed hybrid was 5200 kg/ha in the variant treated with the Euphore process compared to that of the control variant at only 2356 kg/ha. For the Condor variety soybean crop, the highest average number of pods obtained per plant was 195.3 compared 88 pods per plant in the control variant. Thus, the sludge obtained from urban wastewater treatment plants processed using the Euphore method is a good source of macro and micronutrients in agriculture, without having a negative impact on the environment.

“…One of the valid solutions is the use of sludges in agriculture which implies a series of advantages among which natural nutrient intake, soil texture improvement and even water intake, if sludge distribution is performed before its drying. A particularly delicate aspect is that sludges contain, in addition to various beneficial substances, heavy metals, microorganisms, viruses or other pathogens which represent a potential hazard to human and animal health and to the quality of ecosystems, in case they are used as a fertilizer [21][22][23][24][25][26][27][28][29][30].…”

The use of sewage sludge in agriculture decreases the pressure on landfills. In Romania, massive investments have been made in wastewater treatment stations, which have resulted in the accumulation of important quantities of sewage sludge. The presence of these sewage sludges coincides with large areas of degraded agricultural land. The aim of the present article is to identify the best technological combinations meant to solve these problems simultaneously. Adapting the quality and parameters of the sludge to the specificity of the land solves the possible compatibility problems, thus reducing the impact on the environment. The physico-chemical characteristics of the fermented sludge were monitored and optimal solutions for their treatment were suggested so as to allow that the sludge could be used in agriculture according to the characteristics of the soils. The content of heavy metals in the sewage sludge was closely monitored because the use of sewage sludge as a fertilizer does not allow for any increases in the concentrations of these in soils. The article identifies those agricultural areas which are suitable for the use of sludge, as well as ways of correcting some parameters (e.g., pH), which allow the improvement of soil quality and obtained higher agricultural production.
