What is the optimum magnesium level for grass forage crops?

The optimum magnesium level for grass forage crops is recognized to be in the range of 120 to 180 parts per million (ppm). This is because magnesium plays a crucial role in plant physiological processes, including photosynthesis and nutrient absorption. Adequate magnesium levels ensure that grass crops can effectively synthesize chlorophyll and maintain cell and tissue integrity.

When magnesium levels fall below this range, plants may exhibit deficiencies that can lead to issues such as poor growth and reduced forage quality. Conversely, levels exceeding this optimal range could indicate potential nutrient imbalances, which can affect the overall health of the crop and soil ecosystem.

Understanding the optimal range for magnesium is essential for ensuring healthy crop production and maximizing forage quality, which is critical for livestock nutrition and agricultural productivity.
