Calcium and Magnesium are essential secondary nutrients involved in chlorophyll formation and sugar production
Magnesium deficiency appears as interveinal chlorosis (yellowing between veins) on older leaves and may progress to younger leaves and lesion formation
Deficiencies are common in high pH soils (>8) and acidic soils (<6.5)
High levels of calcium and potassium can reduce magnesium uptake
Turf application should be based on soil test results to identify deficiencies
Recommended for season-long use where calcium and magnesium are deficient or marginal
Compatible with fertilizer spray solutions for convenient application
