Background Information

Currently serves as Director of the USDA-ARS National Sedimentation Laboratory (NSL), Oxford, Mississippi, USA, since March 1, 2016.  The NSL consists of two research units, Water Quality and Ecology (WQERU) and Watershed Physical Processes, with a total of 15 scientists.  The NSL research program emphasizes interdisciplinary studies dealing with physical, chemical, and biological processes related to natural resources in agricultural watersheds, and assessing strategies for sustaining and enhancing the integrity and function of agro-ecosystems.

Also serves as Research Leader for the WQERU (2003 - present), a component of the National Sedimentation Laboratory that consists of seven principal scientists and seven support scientists.  The WQERU mission is to conduct high priority research on water quality and ecological processes in agricultural watersheds, developing new technology to improve or restore water quality and ecosystem function in landscapes, streams, and reservoirs that are affected by agricultural activities.  As Research Leader, Dr. Locke is responsible for directing research to ensure that WQERU scientists are conducting a broad scale, high-impact research program that seeks to overcome obstacles to recommended watershed management strategies and meet regional and national needs.

Also serves as Research Leader for the USDA-ARS Delta Water Management Research Unit (DWMRU), Jonesboro, Arkansas, USA (June, 2017 to present).  The DWMRU consists of three principle scientists and one support scientist.  The DWMRU mission focuses on preserving the quality and availability of water resources used in agricultural environments, particularly in the small, rural farms that predominate the Lower Mississippi River Delta area.

Formerly Research Leader of the USDA-ARS Southern Weed Science Research Unit (SWSRU) (now Crop Production Systems Research Unit), Stoneville, Mississippi (1996-2003), consisting of ten principle scientists and two support scientists.  As Research Leader of SWSRU, he was responsible for administering and directing research to ensure that SWSRU scientists were obtaining basic and applied data to develop successful weed management strategies and meets the needs of the region and country.

Dr. Locke has authored or co-authored over 150 technical peer-reviewed publications and presented results at regional, national, and international meetings as author or co-author of over 200 abstracts.  He has national and international recognition as an authority on environmental aspects of conservation management, and has established himself as a substantial contributor and authority in the area of herbicide interactions in soil and water. Dr. Locke is a Fellow in the Weed Science Society of AmericaAmerican Society of Agronomyand Soil Science Society of America.  He has served as an associate editor for three journals: Soil Science Society of America Journal, Weed Science, and Pest Management Science; has co-edited one book, and authored several review articles or book chapters.

Personal Research

 Dr. Locke’s personal research is a broad program assessing agrochemical and conservation management factors that relate to protecting and enhancing soil and water resources.  Specifically, objectives of his personal research are:

 Critically assess effects of management and conservation practices on biological, chemical, and physical parameters in soil and water;

  1. Determine interactions among management effects and factors influencing degradation, sorption and movement, and microbial degradation pathways for agrochemicals such as pesticides and nutrients and develop new technology for improving soil and water resources;
  2. Develop and improve management strategies for minimizing non-target agricultural contamination by agrochemicals in watershed systems and restoring impaired water bodies.
