PhenoRob CP 3: The Soil-Root-Zone
Soil Dynamics and impacts of potential interventions
Abstract
The accurate quantification of soil-root zone processes for application within yield and efficiency analysis is important to increase crop sustainability while conserving global resources. We address the task of measuring soil-root zones of crops in the field and in controlled environment rhizotron systems with minimally or non-invasive sensors and robotics. Sensor data will be ground-truthed at sub-millimeter to meter scales, and aligned with above ground sensor and yield component data and analyses in collaboration with CP1 and CP2 (see http://www.phenorob.de/research/). The overall aim is to develop technologies and scientific concepts for crop yield predictions and optimize resource inputs on farms in real time.
To predict spatial variability of crop biomass and yield in 1D/3D manner, we assimilate observations of below and above-ground processes into a processed-based model, validated by field data.
