Investigation of Physicochemical Properties of flower farms wastewater, and its impacts on nearby river and Soil in Oromia.Ethiopia's flower farm industry today brings in a generous sum of money/income. Although it has made a substantial contribution to economic advancements, communities and environmentalists have expressed concerns about its effects on the environment. In light of these concerns, the study evaluates the Wolmera district's cut flower industry from cradle to gate using a case study methodology. The primary aim of the research was to examine the physicochemical characteristics of the raw water close to the flower farms, the effluent released from the farms, and the soil around the flower farms in the Wolmera district over the course of the cut flower manufacturing life cycle. The study's primary methodology was examining the physicochemical characteristics of soil samples taken from each of the chosen water shades of flower fields, river raw water, and effluent wastewater. The elements that were sampled were assessed and examined through comparison with the national effluent and river water standards (EPA 2003). Nevertheless, the outcomes of the soil sample testing were contrasted with the typical agricultural soil sample evaluation outcomes. The findings of the analysis of the sampled soil (EC, CEC, pH, T-N & P) were much higher than the results of the analysis of ordinary agricultural soil, while the results from the effluent and river water (EC, pH, TDS, SO42-, NO3-, PO43-, COD, BOD5, T-N) were currently below national standards. These very non-degradable pollutants (0.1-0.3) are in addition, degradable and non-degradable elements in wastewater from flower farms were assessed using biological oxygen demand (BOD5) to chemical oxygen demand (COD) ratios. Conversely, both sites have significant effects on environment and its’ elements.

The effect of salt toxicity on soil pH in the northern region of Tébéssa (Aouinet, Morsot, Boukhadra) AlgeriaThis work is the subject of a study of the pH variability of saline soils of the North Tébessa region (Morsott, El-Aouinet, Boukhadra).
In the experiment, soil salinity assessment was performed for the nine samples from the study area (from South to North). We noticed through the results, that the salinity of the soil varies from one region to another, the highest rates are recorded in the area of El-Aouinet and the lowest were recorded in Morsott, May with regard to the acidity of the soil, the results are similar. By comparing the results of the sample analysis, the effect of electrical conductivity, soluble salt level and salinite on soil pH was not observed, so the soil acidity is not affected by the salinity.
