Lori Abendroth

Research Agronomist

Dr. Abendroth is a Research Agronomist within the Cropping Systems and Water Quality Research Unit of USDA-ARS in Columbia, Missouri. She strives to understand and develop cropping systems that are productive with high resiliency to climate change and a low footprint.

Her advanced degrees are in Crop Production and Physiology from the University of Nebraska-Lincoln (MS, 2004) and Iowa State University (PhD, 2019). In her doctoral research, she investigated climate warming trends in the Midwest, changes in commercial hybrid corn maturities as a potential climate adaptation strategy, and corn yield response to improved practices across sites that differ substantially in overall productivity and soil carbon.

Prior to beginning with USDA ARS in 2021, Dr. Abendroth was at Iowa State University in managerial, research, and teaching roles. She has been a part of numerous multi-state and multi-institutional teams addressing climate adaptation strategies, nutrient and water quality, crop productivity, and overall sustainability challenges.

As a Research Agronomist with USDA ARS, she explores the productivity, sustainability, and environmental footprint of our Midwest cropping systems. She is particularly focused on climate adaptation strategies that build resiliency under our current climate and into the future. We are in a time of rapid change and she is striving for her work to advance our scientific knowledge while having strong implications for real-world agriculture.  

Dr. Abendroth conducts research in the Long-Term Agroecosystem Research experiment in Columbia, MO. Learn about the regional and national importance of this research.
LTAR in Missouri: Finding Sustainable Solutions  

  

My research
I explore the productivity, sustainability, and environmental footprint of our Midwest cropping systems. I am particularly focused on climate adaptation strategies that build resiliency under our current climate and into the future. We are in a time of rapid change and I am striving for my work to advance our scientific knowledge while having strong implications for real-world agriculture.

Agronomy is the study of genetics, environment, and management (G x E x M). Altering these components, even slightly, can have a ripple effect on crop productivity and environmental footprints. My research questions include:

• Characterizing climatic hotspots and micro-changes occurring in farming practices,
• Developing systems that increase cropping intensity and diversity,
• Measuring the footprints of our cropping systems particularly as it relates to water use,
• Studying the implications of warmer nights and overall stress on the grain filling period,
• Building high-resolution datasets that illustrate the capacity of our systems for greater resiliency and stabilization.

Why I’m doing this research
Our climate is currently at 416 ppm atmospheric CO2 with 2050 projected to reach 550 ppm. This elevation in CO2 has direct and indirect implications on our agricultural systems. Improving their resiliency to heightened temperatures and differing precipitation patterns is a key area of study. I believe we can integrate robust climate adaptation strategies that meet crop productivity and sustainability goals but this requires large amounts of data to understand slight changes across space and time.

How my research is conducted
My research is primarily conducted at field-scale under row crop (corn, soybean, wheat, cover crops) production. I measure crop development, crop biomass manually and also with an EarthSense robot, photosynthesis and respiration using a LI-COR Photosynthesis System, greenhouse gas emissions with automated samplers, and substantial plant dissection and processing for tissue and grain nutrient concentrations. I pair local field data withlong-term, multidisciplinary data to understand the bigger picture using statistical models.
