Sufferin’ Sulfur
How to Identify
and Treat Sulfur
Deficiency in Plants
by Chris Bond
Sulfur is necessary for plant
health and high yields. Here’s
how to tell if your plants are
lacking this macronutrient,
and what to do if they are.
S
ulfur is one of the few elements that
plants need in larger quantities.
Along with nitrogen, potassium, phos-
phorus, calcium, and magnesium, sulfur
rounds out the six macronutrients that
plants need in sufficient amounts to
maintain good health and achieve high
yields. After nitrogen, potassium, phos-
phorus, sulfur is the fourth most-needed
nutrient that plants require.
