Dr Lucy Crockford BSc (Hons), MSc, PhD
Lecturer in Soil and Water Management
As a Lecturer in Soil and Water Management, I have a wide range of research interests ranging across environmental chemistry, physics and engineering. My primary degree was in Environmental Science at NUI, Galway (2006), with my MSc in Environmental Engineering at Queen's University Belfast (2010) a couple of years after some experience in industry. My PhD research in Geography at the University of Dublin, Trinity College (2015), determined the application of high temporal resolution data in the management of eutrophic water bodies in agricultural catchments. I studied the flow and concentration data of two river catchments with varying drainage capacity and identified the drivers for the eutrophication observed both in-stream and in a lake as an end receptor. Therefore I have great experience in the management and maintenance of high frequency sensors such as HACH datasondes and HACH-Lange Phosphax machines as well as modelling in R and other software packages.
My research at Harper Adams University is primarily in the application of organic amendments to soils and the impact on soil structure and water movement dynamics - as well as the resulting water quality. I'm also very interested in catchments with high sediment movement and I'm looking to expand my knowledge in this area.
My teaching responsibilities range across all levels where I introduce students to general environmental science concepts and at higher levels thoroughly discuss the impact of nutrient cycling systems on soil and water quality. I also deliver a portion of the modules on the new BSc Geography and Environmental Management course. At postgraduate level, I co-supervise one PhD student who is investigating the optimisation of feedstock on anaerobically digested sludge for land application and I teach on a module concerning nutrient cycling and soil and water management. I also provide ad hoc support in environmental modelling and Life Cycle Assessment.

- Crockford L., Jordan P., Melland A R., Taylor D. (2015) Storm-triggered, increased supply of sediment-derived phosphorus to the epilimnion in a small freshwater lake Inland Waters 5 (This study investigated internal loading of sediment-derived phosphorus (P) in a small, meso-eutrophic lake (surface area 0.2 km2, catchment area 2.7 km2, mean depth 6 m, maximum depth 14 m) on the Atlantic seaboard of western Europe. High resolution data collected over 2.5 years (1 Mar 2011 to 30 Sep 2013) revealed inconsistent patterns in (1) the timing and magnitude of lake turnover and (2) the relative importance of the transfer of hypolimnetic sediment-derived P to the epilimnion when compared with external catchment loading. Lake turnover events during spring and summer had the effect of increasing the internal loading of epilimnetic P during the main growing season, thus adding to eutrophication pressure and contributing to algal blooms in the lake. Abrupt pre-fall (autumnal) turnover events and associated increases in eutrophication pressure such as those reported here may become more frequent occurrences in western Europe because of warming-induced increases in Atlantic summer storm frequency and magnitude, and they could counter the apparent effectiveness of measures aimed at reducing eutrophication impacts through limiting external loadings of nutrients from the catchment.)
- O'Dwyer B., Crockford L., Jordan P., Hislop L., Taylor D. (2013) A palaeolimnological investigation into nutrient impact and recovery in an agricultural catchment Journal of Environmental Management 124 (Abstract: Widespread deterioration in water quality as a result of anthropogenic activity has led to the development and implementation of measures aimed at the protection of water resources in the EU. To date, however, relatively little attention has been paid to the effectiveness of these measures. Evidence from an enrichment-sensitive lake permitted reconstructions of changes in ecological and chemical water quality over the last c. 150-200 years, a period that includes a mid to late 20th century intensification of agriculture that was widely experienced across the European Union and the subsequent implementation of measures aimed at protecting water resources against pollution from farming. The data show the development of a more nutrient-tolerant diatom community from early in the 20th century, while the main trophic changes occurred from the 1950s, with the site becoming eutrophic by the 1960s. Heightened enrichment is thought to be linked to enhanced levels of phosphorus (P) transfers from the surrounding grassland catchment owing to an intensification of agricultural activities locally. Most recently, since the late 1990s and particularly post-2007, evidence suggests a decrease in aquatic enrichment, despite continued increases in agricultural intensification. This decoupling is likely to mark a successful implementation in 2006 of measures aimed at decreasing diffuse nutrient transfers from catchments linked to agri-environmental policies in Europe. The research highlights the importance of enrichment-sensitive water bodies as sentinel sites in the monitoring of both external and internal nutrient loadings as agricultural activities and other pressures change within the context of implementing regulatory responses to earlier declines in water quality.)
