Organic pH Down

Acidifies soil or spray tanks

• Soil Acidification
  More effective than elemental sulphur. Works instantly to lower soil pH, increase the availability of iron, phosphorus, and zinc, and inhibit pathogens like Take-All Patch (Gaeumannomyces graminis). Ideal for ericaceous plants such as blueberries, rhododendrons, and camellias.

• Spray Tank pH Control
  Prevents the degradation of pH-sensitive pesticides when mixed in hard or alkaline water. Effective with actives like glyphosate (RoundUp), cypermethrin, and azoxystrobin.

• Worm Casting Management
  Use as part of a soil conditioning program alongside Yucca Extract, Lime Sulphur, and Salicylic Acid to make turf and amenity areas less appealing to earthworms.

• NPK Neutral & Organic
  Will not affect your nutrient regime. The organic acid formulation also supports natural chelation of calcium and micronutrients for improved uptake.

• Biodegradable Formula
  Safe for use in sustainable and organic systems.

How to Use Organic pH Down

pH Adjustment in Spray Tanks

• Soft water: 50 mL per 100 L

• Medium hard water: 150 mL per 100 L

• Very hard water: 200 mL per 100 L

Soil Acidification

Do not apply to very dry soil.

• Dilute 2–4 mL per litre of water

• Apply 100 mL of the diluted solution per m²

• Rinse leaves with clean water immediately after application, but avoid heavy watering into the soil

• Re-test soil pH after rainfall. Repeat if pH remains above 7.0. For ericaceous crops, continue until pH is below 6.0

Fertigation pH Adjustment

• After adding nutrients, test the pH of the solution

• Add Organic pH Down at 0.1 mL per litre until the solution is within pH 5.5–6.5
