Guano Force Silica Max is a high-performance natural fertiliser derived from seabird guano deposits in the Indonesia region, formulated to support both nutrient availability and plant structure.
By combining plant-available phosphorus with naturally occurring silica and supporting minerals, it is well suited to crops requiring strong root development, improved plant strength and sustained performance through environmental stress.
Imported for the Australian market, Silica Max delivers consistent, globally sourced natural nutrition suitable for broadacre, horticultural and plantation use.
As with all Guano Force products, it is naturally processed, environmentally favourable and designed to work with soil biology rather than disrupt it.

Benefits for Your Crop & Soil
Guano Force Silica Max supports natural phosphorus availability while also contributing to stronger plant structure and improved resilience. Sourced from seabird guano deposits with naturally occurring silica, it promotes efficient nutrient use, improved crop robustness and long-term soil function without the aggressive behaviour associated with highly soluble synthetic fertilisers.
Stronger Root Systems
Supports healthy root development, forming the foundation for nutrient uptake and crop stability.
Improved Plant Strength
Naturally occurring silica contributes to stronger cell walls, supporting crop structure and standing power.
Improved Flowering & Yield
Helps plants better utilise available phosphorus for energy transfer, flowering and fruit set.
Stress & Resilience Support
Assists crops in tolerating environmental pressure such as moisture variability and physical stress.
Broad Application Use
Suitable for broadacre and horticultural systems where both nutrition and plant robustness are required.
Soil-Friendly Input
Works with soil biology, supporting balanced nutrient release and long-term soil health.
Application Guidelines
While rates will vary according to soil type, crop, and existing nutrients, here are suggested application routes (note: always base on soil test):
Pre-plant bed preparation: Incorporate granules into the top 5-10 cm of soil before sowing / transplanting.
Side-dressing / Top-dressing: For established crops, apply around the plant dripline and lightly work into the soil, then irrigate.
Container & horticultural crops: Lower rates but more frequent checks are advised; monitor phosphorus and other nutrients.
Important: Do a soil test to ensure your P level is not already high
Storage: Keep product in dry cool space, sealed to avoid moisture uptake.
