TWO M.S. ASSISTANTSHIPS IN SOIL FERTILITY
Two Graduate Research Assistantships for master's level graduate study are currently available in the Department of Crop, Soil, and Environmental Sciences at the University of Arkansas, Fayetteville, for students interested in soil fertility and soil-test development for the sustainable production of agronomically important crops (rice, soybean, corn, cotton, etc). This research will encompass both laboratory and field aspects of soil fertility and soil health research. The selected candidates will incorporate agronomy, soil science, and plant nutrient dynamics while interacting with a diverse group of researchers involved in a variety of soil chemistry/fertility, soil health, and plant nutrition-related projects. Specific projects that are available are outlined below.
Project 1: The first research project will focus on potassium management of irrigated cotton and development of a dynamic critical tissue potassium (K) concentration curve for correcting late-season K deficiency. A portion of the work will focus on investigating cotton responses to K fertilization and identifying critical tissue-K concentrations to help diagnose plant nutritional deficiencies in irrigated cotton production systems. Categorizing the responsiveness of cotton to fertilizer-K applications and the economics of return on fertilizer investment will be a focal point. A primary result of this research will be identifying novel ways to maximize cotton yield related to K nutrition and optimizing producer profitability through increased K use efficiency of cotton.
Project 2: The second research project focuses on the impact of short- and long-term agronomic practices, such as no-tillage, cover crops, nutrient management, and crop rotation, on soil health in Midsouthern US irrigated row crop production systems. Understanding how soil conservation and nutrient management practices affect soil health indices related to key soil functions and their effect on crop yield or production system efficiency is a primary objective of the project. Demonstrating the benefits of soil conservation practices in improving soil health and productivity while maintaining environmental health and sustainability are points of interest.
Required qualifications include a background in soil science with an interest in agronomy, soil fertility, and effective oral and written communication skills. In addition, successful candidates must be self-motivated and exhibit the ability to work independently and as team members. Interested candidates are encouraged to submit a letter of interest, CV, transcripts, and contact info for three references. Applications will be reviewed starting November 10, 2022 but will be accepted until a suitable candidate is identified.
