How does CABR research help farmers grow healthier crops?

In the video below, Lord Gyimah, a PhD researcher at Centre for Applied Bioscience Research (CABR), is quantifying nitrate concentrations in soil leachate samples using the Dionex AS-DV Autosampler in combination with a Dionex ICS Ion Chromatography System, both manufactured by Thermo Scientific. This analytical procedure forms part of his doctoral research.

The objective of the analysis is to accurately determine the concentration of nitrate ions (NO₃⁻) that have migrated through the soil matrix. 

Why measure the concentration of nitrate ions (NO₃⁻)?

Each crop (wheat, for example) requires a different level of nitrate-nitrogen (NO₃-N) concentration for optimal growth, and by analysing the soil, we can ensure the soil quality is adequate for the specific crop type.

The analysis process involves precise sample preparation, calibration with certified standards, and instrumental analysis to identify any statistically significant nitrate concentrations.
