The Fluid Fertilizer Foundation is excited that Dr. Katie Lewis will be presenting a 30-minute webinar updating information on her project “Developing a Fertigation Strategy for Cotton using Subsurface Drip Irrigation.”  The Research Series Webinars present information from FFF sponsored research that influences proper nutrient management and crop production. Join us for the free, live, online event. The webinar will also be available on the FFF website after the event.

Biography
Dr. Katie Lewis joined TTU in September 2014. She received her bachelor’s degree in Chemistry, cum laude, in May 2008 from Sam Houston State University in Huntsville, TX. Her master’s and doctorate degrees, both in Soil Science were obtained from Texas A&M University, College Station, TX. Katie has a joint appointment with Texas A&M AgriLife Research and teaches Soil Fertility class in the Fall Semester.

Dr. Lewis’ goal is to “establish a nationally recognized Soil Chemistry and Fertility Program based on innovative research and competitive graduate student training.”

Research Interests: Soil Fertility, Biogeochemical Cycling, Sustainable Crop Production, Soil Microbiology, Environmental Reclamation, Organic Soil Amendments

Project Summary

What is the best strategy to fertilize a cotton crop using a subsurface drip irrigation (SDI) system? This question is asked quite often particularly by farmers who are new to SDI. Their question more specifically is related to the number of fertilizer applications – should they spoon feed their crop or provide the crop with less frequent larger doses of fertilizer. Not only does this question get asked by farmers but also by irrigation companies. To the best of our knowledge, data does not exist to answer this question specifically related to cotton (Gossypium hirsutum) and phosphorus (P) fertigation; therefore, this research is needed to provide farmers with the best approach to fertigation with SDI. This research focuses on developing a nitrogen (N) and P fertigation strategy that optimizes cotton yield and increases nutrient use efficiency and fertilizer return on investment.
