PhD in Modelling nitrate leaching from farmland – with focus on grass as a field N measure to reduce nitrate leaching.
Research area and project description:
The agricultural sector is the main diffuse source of nitrate loading of our aquatic environment. In Denmark, we have an ambition of reducing the loading and impact of nitrate to fulfill the requirements of the European Water framework directive. In order to reduce the impact on the aquatic environment, knowledge on nitrate leaching levels and dynamics is essential to achieve a more targeted use of field and drain N measures. Knowledge on nitrate leaching loss process from grass clover mixtures can help environmental authorities and farmers to target and optimize use of this field nitrate leaching measures. Furthermore, more measured nitrate leaching data are needed for improving predictions of nitrate leaching from farmland used in the national nitrate leaching predictions.
The PhD focus will includes also expanding the precision/applicability of the empirical model NLES5 for predicting nitrate leaching from horticultural fields. New field leaching data from experiments on horticulture field production systems will be collected from ongoing field experiments, which along with the existing data set behind NLES5 will be the primary data source for theNLES5 development. Other types of data may be included in development of an empirical model predicting nitrate leaching from measured mineral nitrogen contents in the rootzone.
A second part of the PhD project is related to grass production as a measure for protection of the groundwater quality for supply of drinking water. Here, strategies for optimizing grass-clover production in order to minimize N–leaching, while optimizing grass-clover as a source for green protein production will be develop and tested. This work will be in collaboration with other scientists focusing on grass-clover production.
The PhD candidate’s objective is to increase our understanding of processes governing nitrate leaching in agricultural and horticultural systems
The project will be part of the GUDP Project with the Danish title ”Græs til Grøn Protein Produktion – virkemiddel til beskyttelse af grund- og overfladevand – GGP4H2O” and a national funded project ”Sædskiftemodel med grøntsagsforsøg “.
