Mackay 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 changing the way we manage cane soils in the Burdekin. By using 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 lets us pinpoint how nutrients like nitrogen move through the system, where losses are likely, and how to intervene before they reach the reef. Instead of relying on assumptions or trial and error, we now have clear, science-backed insight into processes like denitrification, organic matter cycling, and microbial nutrient retention. It’s a powerful shift: one that helps growers improve crop efficiency, reduce input waste, and actively protect the Great Barrier Reef — all by working with the biology already in their soil.
What is this checklist?
This checklist is a practical tool for sugarcane growers in the Burdekin to assess and improve soil health across the region’s major soil types.
It brings together:
✅ Best-practice soil management tailored to common soil types
✅ Agronomic actions like pH correction, organic matter strategies, and compaction relief
✅ BeCrop® insights into microbial functions (e.g., nitrogen cycling, stubble breakdown)
Each soil type has its own challenges and potential — this checklist helps you match the right actions to the right paddocks, boost nitrogen use efficiency (NUE), reduce nutrient losses, and align with Reef protection goals.
Choose Your Soil Type
1️⃣ Ferrosols (Red Volcanic Soils)
- Often compacted
- Acidic
- Manganese toxicity
2️⃣ Podzolic Soils (Acidic Grey/Brown Sands)
- Low organic matter
- Leaching risk
- Acidity
3️⃣Alluvial Soils (Black/Brown Floodplain Loams)
- Poor drainage
- Sodicity in lower layers
🧬 BeCrop® Biome Focus by Mackay Soil Type
1️⃣ Ferrosols (Red Volcanic Soils)
🧪 Biome Notes: High microbial activity potential due to iron-rich profiles and good mineral diversity; phosphorus often bound in unavailable forms.
🦠 BeCrop® Focus: Root growth promotion, microbial resilience, phosphorus cycling
✅ Practices:
Apply lime or dolomite to lift pH and reduce manganese availability
Use deep-rooted cover crops (e.g. sun hemp) to break compaction biologically
Incorporate compost or mill mud to support microbial communities and CEC
Introduce phosphate-solubilising inoculants to counter P lock-up in acidic conditions
Maintain minimal tillage to protect structure and fungal networks
2️⃣ Red Basaltic Soils (Krasnozems / Ferrosols)
🧪 Biome Notes: Naturally high microbial diversity due to better structure and aeration. Often acidic with phosphorus-fixing tendencies.
🦠 BeCrop® Focus:
Organic matter decomposition, microbial nitrogen cycling, mycorrhizal support
✅ Practices:
Apply stable organic matter (compost, biochar) to buffer nutrient and moisture loss
Use legume interrows or cover crops to rebuild carbon and nitrogen levels
Consider lime + gypsum blends for pH correction and improved structure
Apply microbial biostimulants to promote nitrogen fixation and cycling
Schedule frequent, smaller fertiliser applications (split-N) to reduce leaching
3️⃣ Alluvial Loams (Brown Dermosols)
🧪 Biome Notes: Can support rich microbial diversity if not waterlogged; denitrifying organisms often dominate under poor drainage.
🦠 BeCrop® Focus:
Anaerobic stress monitoring, nitrogen loss risk, carbon turnover
✅ 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

BeCrop® testing supports:
Site-specific biological benchmarking
Functional insight into N cycling, disease suppression, and microbial efficiency
