Maximizing Phosphorus Efficiency: An Introduction

The availability of phosphorus is critical during early growth to get corn off to a quick and healthy start because phosphorus:

•Needs to be available by the V6 growth stage for maximum yield potential

•Is needed for strong root development

•Encourages early plant growth for longer grower seasons (drier corn at harvest)

The final grain yield is influenced by tissue phosphorus concentration prior to the V6 growth stage, regardless of the phosphorus supply at later stages!
