Description

This is a master file of merged excel files with data from several studies on the influence of phosphorus and potassium nutrition on alfalfa. It includes numeric data such as yield, plant mass, plant counts, and tissue concentration of various nutrients. Conventional wisdom states that plants that are poorly fertilized and do not have adequate phosphorus and especially low potassium will become winterkill. This study showed that plants did not necessarily die in winter with low potassium stress. Study dates: 1997 to 2004. Location/Latitude and Longitude: Throckmorton Purdue-Agricultural Center located 15 km south of West Lafayette, IN (40°N and 87°W)
