Understanding the difference between chemical and biological soil health
For decades, soil testing has focused mainly on chemistry — pH, phosphorus, and a few key nutrients. But at AgriSea, we believe there’s far more to soil than what’s soluble right now. Healthy soils are living systems that feed crops, retain nutrients, and support resilience across the whole farm.
Our AgriSea Soil Analysis goes beyond the basics to measure the biological engine of your soil: organic matter, carbon, and microbial activity. These are the factors that tell you how alive your soil is — and how well it can sustain productivity without relying on synthetic inputs.
Why it matters
When you understand what’s locked up in your soil and how your biome can make nutrients available naturally, you can:
- Reduce fertiliser wastage and leaching
- Improve pasture and crop performance
- Build long-term fertility and resilience
- Support animal health through better nutrient cycling
AgriSea Soil Testing Options
Basic Soil Test with Sulphur Profile – $92 excl. GST
Provides the bare minimum: pH, major cations, and sulphur levels. Useful for a quick snapshot of soluble nutrients, but misses key biological and micronutrient data.
AgriSea Essentials Soil Analysis – $224.10 excl. GST (includes 10% off)
Adds key indicators of biological health such as carbon, organic matter, and nitrogen cycling potential. Ideal for farmers ready to move beyond chemical-only testing.
AgriSea Full Spectrum Soil Analysis (Gold Standard) – $317.70 excl. GST (includes 10% off)
Our most comprehensive test, including full micronutrient profiling and reserve nutrients (Total P, Total S, Reserve K). Recommended for baselining or farms that haven’t tested in the past five years.
Why choose AgriSea
Our testing focuses on:
- Biological focus: Measuring life and resilience, not just chemistry
- Nutrient cycling: Understanding what your soil can naturally supply
- Micronutrient health: Finding the trace elements conventional tests miss
- Long-term thinking: Building fertility, reducing losses, and regenerating carbon
- Cost efficiency: Making smarter, evidence-based nutrient decisions
We test deeper — at 150mm instead of 75mm — to ensure results represent the true active root zone, giving you an accurate picture of your soil’s performance.
