Rate My Professor Lucy Greenfield

Greenfield has authored or co-authored at least 19 publications, with her work cited 595 times and read over 6,400 times on ResearchGate. Her research explores critical environmental issues including the effects of micro- and macroplastics on crop biomass, nutrient cycling, microbial biomass, and soil health; microbial degradation of bioplastics like PHBV limited by nutrient availability; impacts of plastic mulch films on nitrogen partitioning, soil microbial diversity, and maize biomass; plant-soil nitrogen dynamics influenced by LDPE and biodegradable PLA-PBAT plastics in barley mesocosms; N2O emissions, microbial communities, and winter barley growth in response to conventional and biodegradable microplastics; soil protease activity assessment methods; root hairs and protein addition promoting leucine aminopeptidase activity in barley; plant use of root-derived proteases for soil organic nitrogen uptake; regulation of soluble protein mineralization and protease activity by supply or demand; and species-specific responses to nitrogen competition between subtropical native tree seedlings and exotic grasses mediated by soil N availability. Key titles include 'Uncovering plant root traits and mechanisms that enable penetration, exploration, and exploitation of soil parent materials: a systematic review' (2025), 'Microbial degradation of bioplastic (PHBV) is limited by nutrient availability at high microplastic loadings' (2024 and correction 2025), 'Field-based assessment of the effect of conventional and biodegradable plastic mulch film on nitrogen partitioning, soil microbial diversity, and maize biomass' (2024), 'Increasing concentration of pure micro- and macro-LDPE and PP plastic negatively affect crop biomass, nutrient cycling, and microbial biomass' (2023), 'LDPE and biodegradable PLA-PBAT plastics differentially affect plant-soil nitrogen partitioning and dynamics in a Hordeum vulgare mesocosm' (2023), and 'Synthesis of methods used to assess soil protease activity' (2021).
