Nutrient balance for the Yalpugh and Cahul river basins in Moldova
Journal Title: Scientific Annals of the Danube Delta Institute - Year 2018, Vol 23, Issue
Abstract
Actual study is focused on calculation of nutrient loads, which reach water ecosystems of the Yalpugh and Cahul rivers, which discharge to the lower Danubian lakes Yalpugh and Cahul located in Ukraine. Article refers to quantitative estimations of nutrient loads originating from different sources and sectors of local economy. On the base of calculation of nutrient coming from main sectors of regional economy a total nutrient budget is calculated for the case-study area. Study showed that main flow of nutrients comes from agricultural lands with superficial runoff, which is responsible for more than 80% of all nutrients. Nitrogen loads predominate in total flow and its ratio to phosphorus could be estimated as 10-13: 1. Presented data show that phosphorus loads are rather limited and for agricultural development this element is a vital one. Loads of nutrients calculated for the region show necessity for development of different scenarios for its reduction and implementation of the soil erosion measures seem to be the most efficient one.
