Rice Yield Response To Potassium: An Economic Analysis
Growing up on a university research farm, Mike Howell developed an interest in agriculture at a young age. While active in 4-H as a child, Howell learned to appreciate agriculture and the programs that would shape his career. Howell holds a Bachelor of Science degree in soil science and a Master of Science degree in entomology from Mississippi State University. He has more than 20 years of experience conducting applied research and delivering educational programs to help make producers more profitable. He takes pride in promoting agriculture in all levels of industry, especially with the younger generation.
Potassium fertilization is a necessity for rice production in the mid-south growing areas of the United States. The paper attached discusses how profit-maximizing rates are related to available soil potassium, applied fertilizer potassium, crop value, and fertilizer cost. This study included 91 site years from 2001 to 2018, and indicates that growers can increase profits by as much as $28.19/ha by utilizing profit-maximizing techniques.
