How Sulfur and Magnesium Support Terpene Production in Plants

Terpenes play a critical role in determining the aroma, flavor, and overall quality of plants.
For growers aiming to produce high-value crops, optimizing terpene production can be an important part of overall crop quality.
Sulfur and magnesium are both essential nutrients involved in plant metabolism, and adequate availability of these elements can support processes related to secondary metabolite production.

​What Are Terpenes and Why Do They Matter?

Terpenes are aromatic compounds produced by plants.
They are responsible for:

• Distinct aromas and flavors
• Plant defense mechanisms
• Overall crop quality and market value

Terpene concentration and composition can influence aroma, sensory characteristics, and market preference in aromatic crops.

​The Role of Sulfur in Terpene Production

Sulfur is an essential nutrient involved in amino acids, proteins, enzymes, and many important metabolic processes. It also contributes to the formation of sulfur-containing compounds that can influence plant aroma.
It contributes to:

• Normal enzyme and protein function
• Formation of sulfur-containing volatile compounds
• Healthy plant metabolism during growth and flowering

While sulfur is important for overall plant metabolism, its direct effect on terpene production can vary by crop and growing conditions and is still being studied.

​Why Magnesium Is Essential

Magnesium plays a central role in photosynthesis and plant metabolism.
It supports terpene production by:

• Acting as a core component of chlorophyll
• Supporting photosynthetic efficiency
• Supporting metabolic processes involved in secondary metabolite production

Insufficient magnesium can reduce photosynthetic performance and may limit normal secondary metabolite production.

How Sulfur and Magnesium Work Together

Sulfur and magnesium support different but complementary functions in plant metabolism.
Together they:

• Support normal photosynthesis and metabolic activity
• Contribute to balanced mineral nutrition
• Support overall plant vitality during the flowering stage

Balanced availability of both nutrients is important for consistent plant performance.

Nutrient Strategies to Support Terpene Profiles

To support healthy secondary metabolite production, growers should focus on balanced nutrition rather than simply increasing individual nutrients.
Key practices include:

• Ensuring sufficient sulfur availability during flowering
• Maintaining adequate magnesium levels throughout growth
• Using appropriate microbial inoculants where they are compatible with the growing system
• Evaluating biostimulant or carbohydrate-containing products based on their formulation and measured crop response

Common Mistakes to Avoid

• Ignoring sulfur levels during flowering
• Underestimating magnesium requirements
• Overfeeding without balance
• Focusing only on NPK while neglecting secondary nutrients

Balanced nutrition is essential for supporting healthy plant metabolism and secondary metabolite production.

Sulfur and magnesium are important components of overall plant nutrition, and magnesium in particular has been shown to influence terpene production in cannabis. However, terpene profiles are also strongly influenced by genetics, environment, plant development, and overall nutrient balance.
