Potassium Decisions: Timing, Sources, and Management Strategies for Maximizing Yields
In this session, we will explore the critical role of potassium in crop production and how informed decisions about timing, sources, and management strategies can optimize yields. We will examine recent field studies conducted across various soils and environments, focusing on pre-plant and in-season applications for corn and soybean. Additionally, we will discuss the integration of plant analysis with soil testing to guide effective fertilization and management decisions.
