It’s light, after all, that is turned into the energy a plant needs to grow strong — and yield high.
In short, light is required for chlorophyll and the process of photosynthesis to make energy for a crop. But what is at the core of chlorophyll? The answer isn’t (likely) the subject of elementary school lessons, but nonetheless plays several imperative roles in plant growth, not the least of which is to ensure a productive photosynthetic process.
As one of three secondary macronutrients (along with calcium and sulfur) required for balanced crop nutrition, magnesium (Mg) plays a critical role in various functions within the plant, and can have a substantial effect on plant growth and yield.
“Although magnesium is a macronutrient, it’s typically not a nutrient that is top of mind when looking at balanced crop nutrition,” says Curt Woolfolk, senior agronomist for The Mosaic Company. “Similar to potassium, we are finding situations where plant-available Mg in the soil may not be keeping up with crop demands, challenging us regarding the best ways to supplement this nutrient and increase yield.”
