STUDY ON NUTRIENT LOSSES IN THE STANDARD EROSION CONTROL PLOTS FROM PREAJBA EXPERIMENTAL POINT, GORJ

Abstract

Recent studies highlight that controlling nutrient emissions from agricultural sources remains one of the most pressing environmental challenges in safeguarding water bodies. The excessive release of nutrients, particularly nitrogen and phosphorus, can lead to the eutrophication of aquatic ecosystems, disrupting water quality and biodiversity. In this context, the present study focuses on the systematic monitoring of agrochemical soil indicators in designated standard plots at the Preajba experimental point in Gorj County. The primary objective is to evaluate and control nutrient losses originating from agricultural practices, with a particular emphasis on understanding the dynamics of nutrient mobility along different topographical positions. Two soil profiles were established for this purpose: one located at the top of the slope and the other at its base. This setup allows for a comprehensive assessment of nutrient losses influenced by slope position, providing critical insights into erosion-driven nutrient transport and soil fertility dynamics. The findings aim to inform sustainable soil and nutrient management practices tailored to mitigate environmental impacts while supporting agricultural productivity.
