Abstract

All crops do not use a proportion of the applied nitrogen (N) fertiliser, but the amount lost varies, depending on the soil type, weather and previous crop. This wasted nutrient can then cause environmental pollution. The development of precision agriculture means that the timing and quantities of fertiliser applications are critical for the narrow profit margins of the industry. Optimal fertiliser supply is required to establish the autumn crop but if too much is applied the excess is wasted as winter rain washes the applied nitrate too deep for the crop roots to access. The way that crops respond to changes in soil N availability, and to determine what limits the capacity to store N when nitrate is abundant are critical questions. This project is using a range of molecular and electrophysiological techniques to measure and manipulate the pools of N present in plant cells. The overall aim is to identify and modify the cellular processes that limit the uptake of N fertiliser by crops.
