Project description
Quantifying how plant roots interact with soil phosphorus
The amount of phosphorus (P) in the soil that is available to plants is very low due to its high reactivity. Plant roots have therefore evolved several strategies to improve P capture. However, as soil is opaque, studying these properties and their potential benefits to crops within the soil environment is difficult. Furthermore, current knowledge is fragmented because studies have generally employed destructive sampling techniques, artificial media, and experimental setups making observations in 1D or 2D. The EU-funded RootOutP project will address this challenge by conducting in-situ visualisation and quantification in real soil, which will benefit plant breeders and agronomists developing crop systems that make better use of applied and accumulated soil P.
Objective
Phosphorus (P) is a scarce resource that is critical for crop production, but it is not being used sustainably. Excessive past fertiliser applications mean large amounts of P have accumulated in soil, losses of which are of major environmental concern. Nonetheless, the majority of soil-P exists in pools of very low bioavailability to plants, due to the high reactivity of P in soil. Increasing the ability of plants to take up P from applied sources (fertilisers) and from accumulated soil reserves would allow for reductions of fertiliser use and decreased potential P losses to the environment. Through evolution, plant roots have adopted several strategies to improve P capture, including: 1) architectural traits that affect the spatial exploration of the soil profile; 2) adaptive (plastic) responses to zones of high P supply (e.g. around fertiliser granules); and 3) physiochemical alteration of the environment in their rhizosphere. A challenge for the research community is to evaluate these properties and their potential benefits to cropping systems. As soil is inherently opaque, these traits are hard to study. Our current knowledge is fragmented because studies have generally used destructive sampling techniques, artificial media, and experimental setups making observations in 1D or 2D. Further advances of our understanding require in-situ visualization and quantification in real soil. This project will deliver such in-situ information, relevant to breeders and agronomists developing crop systems that make better use of applied and accumulated soil P. I will carry out this research under the guidance of Assoc. Prof. Sander Bruun of the Dept. of Plant and Environmental sciences at Copenhagen University and I will make use of the National X-Ray Imaging Facility (DANFIX) and the Center for Quantification of Imaging Data (QIM). I will undertake a secondment with Dr Jakob Santner at the Institute of Agronomy of the University of Natural Resources and Life Sciences, Vienna
