Northern Rivers Sugarcane Soil Health & Biome Checklist
Your Soil Has a Story — Now We Can Finally Read It
Improve nitrogen efficiency.
Protect Reef water quality, and build soil function tailored to your soil type.
Reading the Soil: A New Approach to Protecting the Reef
New tools are transforming how we manage sugarcane soils in the Northern Rivers.
With BeCrop® DNA sequencing and AI-powered analysis, we can now “read the soil” — not just its chemistry, but its living biology and how it functions. This allows us to pinpoint how nutrients like nitrogen behave in local soils, where losses or inefficiencies are likely, and how to intervene early and effectively.
Instead of relying on trial and error, growers now have clear, science-backed insights into processes like denitrification, organic matter cycling, and microbial nutrient retention. It’s a powerful shift — one that helps improve nitrogen efficiency, reduce input waste, and boost productivity by working with the biology already present in the soil.
What is this checklist?
This checklist is a practical tool for sugarcane growers in the Northern Rivers to assess and improve soil health across the region’s major soil types.
It brings together:
✅ Best-practice soil management tailored to volcanic, alluvial, and sodic landscapes
✅ Agronomic actions such as pH correction, organic matter recovery, and compaction mitigation
✅ BeCrop® insights into microbial functions — including nitrogen cycling, denitrification risk, and root zone health
Each soil type comes with its own challenges and potential. This checklist helps you match the right practices to the right paddocks, improve nitrogen use efficiency (NUE), reduce nutrient losses to waterways, and support sustainable productivity in the Northern Rivers.
Choose Your Soil Type
1️⃣ Basalt-Derived Ferrosols (Red Volcanic Soils)
- Surface crusting
- Acidity
- Compaction
- Phosphorus fixation
2️⃣ Alluvial Loams (Floodplain Soils)
- Waterlogging
- Sodicity in subsoil
- Denitrification risk
3️⃣Acidic Duplex Soils (Sodic Subsoils)
- Poor infiltration
- Sodicity
- Acidity
- Shallow topsoil
🧬 BeCrop® Biome Focus by Northern Rivers Soil Type
1️⃣ Basalt-Derived Ferrosols (Red Volcanic Soils)
🧪 BeCrop® Focus:
Phosphorus cycling
Fungal:bacterial balance
Root-microbe interactions under low pH
🦠 Biome Notes:
High microbial potential due to diverse minerals. Acidic pH often suppresses beneficial fungi unless managed.✅ Practices:
Lime or gypsum for pH and structure correction
Legume rotations to boost microbial diversity
Use biostimulants that support fungal networks
Reduced tillage to stabilise biological layers
2️⃣ Alluvial Loams (Floodplain Soils) Ferrosols)
🧪 BeCrop® Focus:
Anaerobic nitrogen loss tracking
Carbon turnover under wet–dry cycles
Microbial buffering of pH and salinity
🦠 Biome Notes:
Microbial populations often shift toward denitrifiers; risk of nitrogen loss unless drainage is addressed.✅ Practices:
Install or maintain drainage
Monitor ammonium vs nitrate dynamics
Use organic matter inputs to improve structure
Apply biostimulants tolerant to wet-dry fluctuation
3️⃣ Acidic Duplex Soils (Sodic Subsoils)
🧪 BeCrop® Focus:
Biological infiltration support
Microbial indicators of sodic breakdown
Root zone stress diagnostics
🦠 Biome Notes:
Surface can host high bacterial activity, but sodic layers below restrict root access and biological penetration.✅ Practices:
Deep ripping + gypsum to break subsoil sodicity
Maintain stubble/cover to protect surface
Select microbial blends for stress tolerance
Add compost or carbon-rich materials to feed shallow soil life
✅ Practices:
Conduct drainage mapping (e.g. drone DEMs) and implement laser levelling where needed
Use raised beds or furrow design to manage waterlogging
Incorporate organic inputs with high calcium to counter sodicity (e.g. gypsum + compost)
Apply BeCrop® monitoring to detect denitrification zones and manage N losses
Encourage surface cover and minimum tillage to prevent crusting and erosion
