Eutrophication meaning

Eutrophication Potential Eutrophication potential leads to an increase in aquatic plant growth attributable of nutrients left by over-fertilization of water and soil, such as nitrogen and phosphorus. From: Assessing and Measuring Environmental Impact and Sustainability, 2015 Related terms: • Energy Engineering • Life Cycle Assessment • Environmental Impact • Acidification Potential • Global Warming Potential • Greenhouse Gas • Ozone Depletion Potential • Measurer Regarding EP, the results from 12 studies were analyzed as shown in Fig. 10A and B. The mean impact on EP is 0.32kgPO 4eqodt −1 (±0.26 SD), with the median of 0.21kgPO 4eqodt −1 of produced feedstock (dry matter). The differences between the mean and the median were mainly attributed to the low EP (0.073kgPO 4eqodt −1) values and high EP (0.8kg PO 4eqodt −1) reported by Laschi et al. (2016) and Parajuli et al. (2017), respectively. The low EP found by Laschi et al. (2016) was because of the exclusion of fertilizer and agrochemical applications. In contrast, in the study of Parajuli et al. (2017), the high EP was mainly due to field emissions, such as nitrate leaching, as well as ammonia and phosphate emissions, which contributed 40% of the total EP, and then followed by agrochemicals production. This result was slightly different compared to the other studies, which normally indicated that the fertilizer and agrochemicals application were the major EP impact factor contributors.
