Investigating a nature-based solution for agricultural runoff in Ireland: Identification of nutrient/trace element accumulator plant species and their microbial interactions
Diffuse water pollution from agricultural sources in the form of excessive nutrient run-off and drainage discharge is a persistent global contamination source of water quality in rural and agricultural catchment streams and a growing challenge in farming systems. Numerous studies have reviewed the effectiveness of vegetative buffer strips (VBSs) in retaining nutrients from runoff and overland flow. Moreover, VBSs separate agricultural land management activities from water courses by dispersing runoff through thick vegetation and root networks. The microbial constituents of plants, such as arbuscular mycorrhizal fungi (AMF), have been shown to improve plant growth, nutrient transformation, and accumulation, and have great potential to improve phosphorous tolerance and phytoremediation. This PhD project will focus on the (1) identification of native (Irish) nutrient accumulator (VBS) plant species in agricultural settings and their functional characteristics, (2) identify and characterize associated AMF and/or other microbial constituents with selected plants, and (3) assess nutrient accumulating capabilities of plants with native and/or inoculated AMF. Results from this study will contribute to the aim of the NuReCycle project by establishing a sustainable way that farmers can myco-phytoremediate agricultural soils, and in turn, use these plants at the end of a season as a nutrient sorbent biochar/natural overwintering green manure.
NuReCycle is an interdisciplinary project that explores factors driving diffuse water pollution from agricultural sources in Ireland and seeks to develop integrated nutrient control, recovery, and recycling systems. The project is generously funded by a Kinsella Challenge-based E3 Multi-disciplinary Project Award. For more information see https://www.tcd.ie/e3/research/e3-phd-programmes/phd-projects/
This award provides a unique opportunity for a doctoral student to pursue interdisciplinary research in the thriving intellectual community at Trinity College Dublin. Based in the School of Natural Sciences in the Botany Department, and enrolled in the Research PhD Programme, the PhD student work will closely with the other researchers involved in NuReCycle.
Applications should be made through the E3 website by 30th November 2021.
