Kansas Fertilizer Research 2013

Abstract

The 2013 edition of the Kansas Fertilizer Research Report of Progress is a compilation of data collected by researchers across Kansas. Information was contributed by faculty and staff from the Department of Agronomy, Kansas agronomy experiment fields, and agricultural research and research-extension centers. We greatly appreciate the cooperation of many K-State Research and Extension agents, farmers, fertilizer dealers, fertilizer equipment manufacturers, agricultural chemical manufacturers, and representatives of various firms who contributed time, effort, land, machinery, materials, and laboratory analyses. Without their support, much of the research in this report would not have been possible. Among companies and agencies providing materials, equipment, laboratory analyses, and financial support were Agrium, Inc.; Cargill, Inc.; Deere and Company; U.S. Environmental Protection Agency; FMC Corporation; Fluid Fertilizer Foundation; Foundation for Agronomic Research; Honeywell, Inc.; Hydro Agri North America, Inc.; IMC-Global Co.; IMC Kalium, Inc.; Kansas Agricultural Experiment Station; Kansas Conservation Commission; Kansas Corn Commission; Kansas Department of Health and Environment; Kansas Fertilizer Research Fund; Kansas Grain Sorghum Commission; Kansas Soybean Commission; Kansas Wheat Commission; Iogen Corporation; MK Minerals, Inc.; Nutra-flo; Monsanto; Pioneer Hi-Bred International; International Plant Nutrition Institute; Pursell Technology, Inc.; Servi-Tech, Inc; The Sulphur Institute; Winfield Solutions; and U.S. Department of Agriculture–Agricultural Research Service. Special recognition and thanks are extended to Troy Lynn Eckart of Extension Agronomy for help with preparation of the manuscript; Kathy Lowe and Melissa Pierce, the lab technicians and students of the Soil Testing Lab, for their help with soil and plant analyses; and Mary Knapp of the Weather Data Library for preparation of precipitation data.
