TerraSoil Yield Master Soil Blend - 500g - Organic Soil Blend

As a complete soil blend

• Mix 75% quality potting soil with 25% worm humus.
• Add 10 g of Yield Master per litre of mix (about 1 small handful for every 10 L of soil).
• Blend thoroughly before filling pots or beds.

Top-dressing established plants

• Sprinkle up to 200 g per plant evenly over the soil surface.
• Gently work into the top few centimetres and water well.

When to apply

• At the start of the grow when preparing your soil.
• As a top-dress during the season if plants show signs of hunger or to support heavy flowering.

Tips for maximum yields

• Use pH-balanced, dechlorinated water for best nutrient uptake.
• For very heavy feeders, you can improve nitrogen with products like Azospirillum brasiliensis or horn meal (around 250 g) and boost potassium with worm humus, kelp meal, wood ash or mined potassium sources.
• For extreme yields, combine Yield Master with TerraSoil Flower Topper during flowering.

Yield Master combines natural minerals, organic matter and biological inputs to feed both your plants and the soil.

• Granite & Basalt Rock Dust
  Provide a broad range of trace minerals (iron, magnesium, silica, etc.) that support strong plant structure and resilience.

• Gypsum & Bentonite Clay
  Improve soil structure, water-holding capacity and nutrient retention, creating a better environment for roots and microbes.

• Rock Phosphate & Bat Guano
  Supply phosphorus and additional nutrients needed for root development, flowering and fruiting, especially in high-yield crops.

• Seaweed (Kelp)
  Adds natural potassium, trace elements and growth stimulants that support overall plant health and stress resistance.

• BioChar & Leonardite
  Increase nutrient-holding capacity and provide carbon to support a thriving soil food web.

• Dolomite & Insect Frass
  Add calcium and magnesium, gently balance pH and contribute extra nitrogen and beneficial compounds from insect frass.

Together, these ingredients create a balanced, living soil blend that can sustain plants through vigorous growth and heavy harvests with fewer bottled inputs.
