TerraSoil Elemental Sulphur (500 g Tub)
-
Precise pH Lowering
Fine elemental sulphur gradually converts (via soil bacteria) into sulphuric acid, reducing soil pH in a controlled way, ideal for acidic-loving plants, soil correction, or pH adjustments. -
Strong Purity & Reliability
With 99.95 % purity and minimal impurities, each application is consistent, effective, and safe for use on food crops when handled properly. -
Dual Role: Fertilizer + Defense
Supplies sulphur, an essential macronutrient — while also acting as a fungicide / mild pest suppressor when applied correctly (e.g. dusting). -
Fine Particle for Uniform Coverage
The very fine powder ensures even spreading and good contact with soil or plant surfaces. -
Sustainably Packaged & Stored
Supplied in a resealable 500 g tub to preserve quality, reduce dust loss, and facilitate safe handling.

Use Case Recommended Rate Instructions / Notes Soil / Substrate pH Correction ~1 g S per kg soil lowers ~1.5 pH units (estimate; adjust for soil type) Mix thoroughly into the upper layer of soil; water in well. For heavy clays or buffered soils, more may be needed. Around Individual Plants 50–100 g per plant, worked into topsoil Apply in a ring around stem (at safe distance), water after applying to activate. Field / Farm Use Up to 15 kg/acre (adjust based on test) Use equipment to spread evenly and mix into topsoil. Fungicide / Dusting Use Light dust on affected surfaces Use a dry air stream / blower to apply a thin coating; reapply as conditions allow. Parameter Value / Description Purity 99.95% elemental sulphur (minimum) (TerraSoil) Max Acid Content ≤ 0.01 % (TerraSoil) Particle Form Very fine powder / dust (TerraSoil) Packaging Resealable 500 g tub Storage Conditions Keep dry, sealed, in cool, ventilated area, away from ignition sources and oxidizers (TerraSoil) Safety Use dust mask, gloves when handling fine powder (TerraSoil) Elemental sulphur (S⁰) is oxidized by soil microbes (e.g. Thiobacillus spp.) into sulphuric acid (H₂SO₄) over time. This acidification lowers pH and releases sulfate (SO₄²⁻), an essential sulphur nutrient for plant growth.
-
Fine particles speed up microbial oxidation by increasing surface area.
-
The acid generated improves micronutrient solubility (Fe, Mn) in slightly alkaline soils.
-
Because conversion is gradual, sulphur offers safer pH adjustment compared to strong acids.

1. Can I apply sulphur just before planting?
Yes — but allow a few days (or ideally 1–2 weeks) if possible, so microbial oxidation begins and pH adjustment moderates before seed germination or root establishment.2. Is this safe for edible crops?
Yes, when used within recommended ranges and in well-aerated soils. Rinse or water in after foliar dusting to reduce residual surface residue.3. What kinds of plants benefit most?
Acidophilic or pH-sensitive plants (e.g. blueberries, azaleas), or soils suffering from alkalinity or calcareous residues.4. Can I mix with other fertilizers or amendments?
Yes, but avoid mixing directly with nitric fertilizers or oxidizers. Incorporate into soil first, then apply fertilizers.5. How often should I reapply?
Depending on soil buffering capacity, crops, and pH drift, one application per season or every few seasons may suffice. Monitor soil pH and sulphate levels to decide.-
