Q88. How do I add more carbon to my soil?
To build soil carbon, focus on boosting root growth, limiting erosion, retaining stubble, using pastures and cover crops, managing soil constraints, and minimising disturbance.
Q87. How do I get an accurate carbon baseline and can I do it myself?
No, you can’t do your own carbon baseline for carbon farming – sampling must be done by an independent, qualified provider after the project is
Q86. What test should I use to measure soil organic carbon?
Choose a soil organic carbon test based on your goal—use the same method for monitoring changes over time, Walkley Black for general farming, or dry
Q80. Can I fully rehabilitate a seep area (i.e. crop it like the rest of the paddock) and how long will it take?
Yes, Mallee seeps can be fully rehabilitated for cropping, but success and timeframes – typically 3-5 years – depend on salinity levels, seep severity, and
Q76. Can I punch a hole in the clay at the bottom of a seep so the water will drain out the bottom?
No, punching through the clay beneath a seep isn’t practical or permitted, and managing seeps with above-ground solutions is safer and more effective.
Q78. How do I find a seep before it becomes a problem?
You can spot a developing Mallee seep early by looking for persistent green growth, waterlogging, and ryegrass invasion, then confirming with NDVI imagery and digging
Q73. Why are Mallee seeps appearing in my paddock?
Mallee seeps form when excess water accumulates above shallow clay layers, creating perched water tables that raise salinity and waterlog soils, eventually making them unproductive.
Q72. What’s the difference between a Mallee seep, magnesia patches and dry saline land?
Mallee seeps are caused by rising saline water tables from perched water, while magnesia patches or dry saline land result from salt wicking up through
Q69. Does drought make soil water repellent?
Drought doesn’t cause water repellence but worsens it by drying soil further, strengthening hydrophobic bonds and reducing microbial breakdown of repellent compounds.
Q66. Do I need to change my fertiliser strategy during drought?
Yes, drought conditions require adjusted fertiliser strategies—apply less upfront, rely on soil testing, and target nutrients efficiently based on crop demand and root access.
