Sulfur, Prilled, True Organic

Soil Acidifier and Micronutrient for pH Balance and Plant Health

True Organic Prilled Sulfur is a finely granulated elemental sulfur ideal for amending alkaline soils and supporting plant sulfur needs. This slow-release, OMRI-listed input helps lower soil pH over time, making nutrients more available-especially iron, manganese, and phosphorus-in high pH soils. It also supplies sulfur, a critical micronutrient for protein synthesis, enzyme formation, and chlorophyll production in plants.

Recommended for blueberries, azaleas, onions, garlic, brassicas, and acid-loving fruits, as well as for balancing soil in regenerative, organic, and no-till systems.

Key Characteristics

• Gradual Soil Acidification for Alkaline Soils
  Prilled sulfur lowers soil pH slowly and steadily as soil microbes oxidize it into sulfuric acid. This is particularly valuable for growers working with calcareous soils or aiming to grow acid-loving crops like blueberries, rhododendrons, or potatoes.

• Supplies Essential Sulfur for Plant Metabolism
  Sulfur is vital for the production of amino acids, vitamins, and enzymes. Plants deficient in sulfur often show stunted growth and pale foliage. This amendment helps ensure healthy leaf development, disease resistance, and flavor in allium crops and brassicas.

• How to Use in Garden, Orchard, or Field

  • pH adjustment: Apply 1-3 lbs per 100 sq ft for each point of pH reduction desired (based on soil test).

  • General nutrient support: --1 lb per 100 sq ft lightly worked into the topsoil.

  • Tree and shrub basins: --- cup around drip line of acid-loving perennials.

  • Timing: Best applied in spring or fall; allow 4-8 weeks for microbial breakdown.

• Compatible with Biological Soil Systems
  Works well in conjunction with compost, microbial inoculants, and organic matter to gradually buffer and correct soil chemistry without shocking soil life. Beneficial in orchard guilds, berry beds, and diverse perennial systems.

• Best For These Crops and Situations

  • Blueberries, cranberries, grapes, strawberries

  • Onions, garlic, cabbage, broccoli, kale

  • Potatoes, rhubarb, and acid-loving ornamentals

  • Soil remediation and pH adjustment in new beds or alkaline zones
