Past Scholarship Winners

Anaya Hall, Anne Hallee & Onnr Grogan – 2019/2020 Young Investigator Scholarship Winners

Anaya Hall is a PhD student in the Energy and Resources Group at UC Berkeley where she focuses her research on data-driven models of coupled human and natural systems. She earned an MS from Tufts University in Agriculture, Food & Environment and a BA from Stanford University in Human Biology. As a PhD student, she is building on her interdisciplinary background linking ecological and economic sciences to promote equitable, sustainable, and climate-resilient food systems.

Anaya’s project will develop a spatial model for the state of California to connect organic waste streams with composting infrastructure and working lands in order to critically evaluate the feasibility and anticipated abatement costs of using composted municipally-generated organic waste as a soil amendment to both sequester carbon and meet state-level diversion requirements. This analysis combines spatial optimization and life-cycle assessment to consider the technical, economic, and institutional potential of actively managing the State’s food scraps and green waste for climate change mitigation. The research models a range of scenarios to estimate the cost per ton CO2eq of this abatement strategy and provides the first approximation of the potential impacts of organic waste management for soil carbon in California.

Anne Hallee is currently enrolled at The Evergreen State College in Olympia Washington pursuing her Bachelors of Science Degree with a focus in Chemistry.  She brings a background in sustainable agriculture and nutrient management planning to her academic focus in plant nutrient cycling and the symphony of microbiology at play in soil chemistry.  She plans to work in the agricultural sector as an educator and researcher.

Anne’s research project will investigate phosphorus availability in composts of varying feedstocks.  She will assess the amounts of soluble, plant available phosphorous typical of compost samples from static aerated composting facilities targeting three groups of feedstock types: manure based, green waste based and food scrap-based composts when applied to a low fertility soil.  Her project will involve compost characterizations, soil blends and an incubation mimicking a growing year to evaluate the representative phosphorous availability in land applied compost products. The information gathered from this study will inform the composting community of phosphorus content within various feedstocks, offer guidance for determining composting recommendations that limit phosphorus losses into the watershed, and inform best management parameters for manure-based compost, green waste-based compost and food waste-based compost.

Here's the Winner of the Special North Carolina Scholarship
donated by the North Carolina Composting Council

Onnr Grogan is a junior in the undergraduate Biological Engineering program at North Carolina Agricultural and Technical State University. The objective of her project is to determine how the method and schedule of turning a compost affects the temperature profile, nutrient contents, and time required for production of the compost. Wooden open-air pens will be compared to tumbler bins for ease and efficiency. Additionally, the turning schedule will be varied to determine the ideal frequency for compost turning with each method.

The long-term goal of her project is to develop the infrastructure and a process necessary to begin a comprehensive compost program through the main dining hall on campus. A cost benefit analysis will be performed to determine the economic sustainability of a continuous composting program compared to the current process of discarding all food in a trash compactor. When the project is completed, the plan is to present a proposal for a continuous composting program to the NC A&T Chancellor and a representative of Sodexo, the school’s food service provider.

 

Donald De Alwis & Sally Landefeld – 2018/2019 Young Investigator Scholarship Winners

Donald De Alwis is currently studying towards dual degrees in Environmental Science and Public Health Science at the University of Maryland, College Park. He specializes in environmental health, and enjoys exploring the interface between humans and the environment. He hopes to continue researching the human-environment nexus after his bachelor’s degree through a graduate or professional degree program.

Donald’s project focuses on the use of locally sourced compost to facilitate hydric soil conditions in wetland restoration. He will use cow manure and Bloom, a biosolid produced by a local water utility company, at three different cure times. Through a soil microcosm experiment, he will analyze ferrous iron and methane production with the intention of determining which soil amendment and cure time maximizes microbial activity while reducing greenhouse gas production. The results of the experiment will determine the feasibility of a novel use for compost, and will inform restoration practices for Maryland’s vast wetland ecosystems.

Sally Landefeld received a BA in chemistry from Occidental College in Los Angeles. Upon realizing that many preventable chronic diseases stem from lifestyle and food nutritional quality, Sally changed her plans to attend medical school and left the biomedical research field to focus on the root of the issue: soil health. She earned a MS in Environmental Science and Engineering from Oregon Health and Science University in 2017 and is pursuing a PhD in Civil and Environmental Engineering at the University of Washington.

Sally’s research aims to characterize the relationship between soil health and plant health: Does healthier soil grow healthier food? This project is looking at common garden crops grown in four types of soil amendments: composted biosolids from Pierce County (TAGRO), composted biosolids from King County (GroCo), vermicompost, and bokashi. These soils will be tested for a suite of chemical, physical, and biological properties to characterize the soil health, and crops are undergoing analysis for macronutrients, micronutrients, vitamins, and phytonutrients that act as potent antioxidants. Sally is hoping that her project may help “close the loop” on urban waste, provide fertile soil to local urban gardens, and sequester carbon in the form of soil organic matter.

 

Russell Galanti – 2017/2018 Young Investigator Scholarship Winner

Russell Galanti is from Maryland originally and got his undergraduate degree in Horticulture Science from Temple University in Pennsylvania. He is now completing his Master's in Tropical Plant and Soil Science at the University of Hawaii at Manoa. He plans to continue his research in improving agro-ecosystem cultural management under the context of sustainable agriculture.

Russell's project focused on looking at the effects of five locally sourced soil amendments on plant health and production and soil properties in macadamia orchards. The treatments were wood chip mulch, macadamia husk mulch, husk mulch with biochar, husk mulch with lactic acid bacteria inoculation, and soil profiling. He looked at tree yield, root growth, and tissue nitrogen, as well as soil organic matter, soil nitrogen, pH and electrical conductivity. This project focused on protecting Hawaii's limited natural resources, reducing the need for external resources. A cost benefit analysis was also be performed to determine the economic suitability of such treatments.

 

Clara Tang – 2016/2017 Young Investigator Scholarship Winner

Clara Tang, a master's student at North Carolina State, was chosen based on her project - looking at exploring alternative ways to manage soils more sustainably and seeking to understand the impacts of the use of compost on soil health. Her project evaluated the interactive effect of mycorrhiza and compost on soil and plant health by looking at the change in physical, chemical, and biological properties of soil and how that relates to plant growth. The main focus of the study was to determine the changes in the microbial communities by contrasting sterilized treatments to non-sterilized and determining if the beneficial effects of compost and mycorrhiza were due solely to nutrient addition or also enhanced by the microorganism present in these amendments.

 

Brandon Erny – 2015-2016 Young Investigator Scholarship Winner

Brandon Erny’s winning proposal, "Investigating the use of biochar to increase nutrient retention in compost-production, and following compost spreading," tested the role of biochar, charcoal used for soil amendment purposes, on retaining soil nutrients that normally escape in the compost process. Erny was compost manager at Sterling College in Vermont, where he studied carpentry and sustainable design.
