Agronix Guano 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 Agronix products, it is naturally processed, environmentally favorable and designed to work with soil biology rather than disrupt it.

General Guidelines
| Category | Recommendation |
|---|---|
| Application method | Apply as a granular fertiliser via air seeder, spreader, or banded application |
| Crop suitability | All crops (broadacre, horticulture, pasture, turf) |
| Rate selection | Use lower rates for sensitive crops or when applying in-furrow |
| Blending | Compatible with most granular fertilisers; confirm before blending |
| Application conditions | Avoid excessive application rates in the seed zone |
| Air seeder use | Ensure compatibility with fertiliser blends and avoid excessive salt loading in the seed zone, particularly when combined with starter fertilisers |
Application Rates Simplified Guide
| Application Method | Rate | When to Use |
|---|---|---|
| In-Furrow (Air Seeder) | 20–50 kg/ha | At planting for early root development and establishment |
| Broadcast / Soil | 50–150 kg/ha | Pre-plant or during crop growth |
| High-input program | 150–300 kg/ha | Where soil constraints or deficiencies exist |

Benefits for Your Crop & Soil
Agronix Guano Silica Max delivers naturally occurring phosphorus and supporting minerals in a form plants and soils can use efficiently over time. Sourced from seabird guano deposits, it supports strong root systems, improved flowering and long-term soil health without the harsh spikes associated with highly soluble synthetic fertilisers.
Stronger Root Systems
Enhances root development, phosphorus is key for strong root systems.
Mineral-Rich Nutrition
Supplies beneficial minerals (e.g., calcium, magnesium) supporting soil biology, structure and long-term fertility.
Improved Flowering & Yield
Promotes vigorous flowering and fruit set: plants can better utilise the available phosphorus for energy transfer, bloom, and yield.
Balanced Nutrient Release
Slow to moderate release compared to highly soluble synthetics — better matched to soil biological activity and more forgiving for large scale or horticultural applications.
Broad Application Use
Ideal for both broadacre and horticultural use, particularly where phosphate is limiting, or you’re seeking a natural / low-chemical input route.
Soil-Friendly Input
Naturally gentle on soils, supporting biological activity and reducing the risk of nutrient lock-up or root burn compared to aggressive soluble fertilisers.
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.
