Connecting Soil Nitrogen and Plant Uptake for Greener Agriculture

Grant number: DP200101162 | Funding period: 2020 - 2023

Completed

Abstract

This project will use synthetic organic chemistry, biochemistry, root and rhizosphere biology and rhizosphere modelling to establish detailed mechanistic knowledge of the nitrogen (N) transport and uptake processes at the soil-root interface to develop new, efficient urease and nitrification inhibitors for reliable provision of N to the plant/root system. The reduction of excessive N fertilisation has significant environmental benefits by reducing greenhouse gas emissions and water pollution. This project will lead to a breakthrough for the triple challenge of food security, environmental degradation and climate change, while improving plant productivity and increasing the profitability of a..
