Liangxiu Han: 1843: What did the longest running crop experiment discover about nitrogen?

Nitrogen is the nutrient with the biggest impact on crop growth but monitoring its use by the plant is problematic.
Prof. Han has led the development of innovative precision agriculture solutions such as automated crop disease diagnosis and automated nitrogen diagnosis tools using big data/machine learning/ AI, robotics and various large datasets from remote sensing (Satellite, Drone), Smartphone and IoT to address challenges to food security.
Prof. Han explains: “Current methods of analysing crop metabolism are destructive and time consuming and require laboratory analysis of plant material. Measuring nitrogen in soil is also difficult as it is impacted by soil type, temperature, moisture content and microbial activity, so removing samples can also change the relative amounts of different forms of nitrogen.
“What is required is an autonomous, non-destructive method of measuring nitrogen that can determine the gap between bioavailability in the soil and the requirement from the plant.”
Prof. Han is working with Dr Mark Lee, Royal Botanic Gardens Kew, an expert in plant leaf and soil analysis, and Aron Kisdi of GMV Innovative Solutions, developers of the robotic rover platform to offer automated intelligent soil and plant nitrogen diagnosis.

REAP 2021: Changing Time(s) for Agriculture – 10th November 2021

Imagine a world where agriculture is not constrained by time. The ability to manage and manipulate time is increasing and REAP 2021 will explore the advances in technology and breakthroughs in science that is making this possible.
REAP brings together people from across the agri-tech ecosystem who believe that innovation is the engine for change. The conference bridges the gap between producer needs and technology solutions and showcases exciting agri-tech start-ups.
