What is the optimum magnesium level for crops other than grass forage crops?

The optimum magnesium level for crops other than grass forage crops is indeed in the range of 60 to 120 ppm. Magnesium plays a crucial role in photosynthesis as it is a central component of chlorophyll and also aids in the activation of many enzyme systems that facilitate plant growth and development.

In this range, crops can efficiently utilize magnesium for their physiological processes without experiencing deficiency or toxicity issues. For most crop types outside of grass forages, having magnesium levels in this optimal range promotes healthy root development, proper nutrient uptake, and ultimately contributes to improved yield and quality of the crops.

The concentrations below or above this range might not provide the same beneficial effects for crop health and productivity, making the specified range of 60 to 120 ppm the ideal target for ensuring robust crop growth.
