Improving carbon levels in sandy soils requires a combination of strategies. Start by incorporating cover crops like legumes or grasses to build organic matter. Minimise soil disturbance by adopting no-till or reduced-till practices to protect carbon already stored in the soil. Adding organic amendments such as compost or manure can also boost carbon levels over time. Finally, ensure your soil is well-covered year-round to prevent erosion and retain nutrients.

Carbon farming involves practices like planting high-biomass crops, reducing tillage, and using cover crops to capture atmospheric carbon and store it in the soil. This increases organic matter, improves nutrient cycling, and boosts soil health, leading to higher fertility and productivity.

Rotating diverse crops, such as legumes, cereals, and oilseeds, reduces pest pressures, breaks disease cycles, and enhances nutrient availability. Incorporating nitrogen-fixing crops like legumes can naturally replenish soil nitrogen, improving both soil health and yield potential.

Rotational grazing allows pastures to rest and recover, promoting deeper root growth and increasing organic matter in the soil. It prevents overgrazing, improves water retention, and distributes nutrients more evenly across the land, leading to healthier soil and more productive pastures.

To enhance drought resilience, focus on increasing soil organic matter through compost or cover crops to improve water retention. Reduce tillage to maintain soil structure and minimise evaporation. Practices like deep ripping and mulching can also help retain moisture and reduce surface runoff.

Why is soil health a major focus for MSF?

Building Soil Function

Healthy soils are vital for sustainable farming. MSF promotes practices like soil amelioration, cover crops, and carbon farming to improve soil structure, fertility, and resilience against erosion and salinity.

What is a Mallee Seep?

Soil and Carbon

A Mallee Seep occurs when a perched water table brings saline water to the soil surface, creating patches of unproductive land known as saline scalds. These can significantly reduce crop and pasture yields.

How does MSF help farmers manage Mallee Seeps?

Soil for Drought Resilience

MSF offers tools like the Mallee Seeps Decision Tree, research insights, and practical guidance to help farmers identify, assess, and rehabilitate areas affected by Mallee Seeps.

What does MSF do?

Soils and Cropping

MSF conducts innovative on-farm research, hosts educational events, and provides resources to address key challenges like soil health, drought resilience, and sustainable farming practices in low-rainfall regions.

Who is Mallee Sustainable Farming (MSF)?

Soils and Livestock

MSF is a farmer-driven organisation dedicated to improving the productivity, profitability, and sustainability of low-rainfall farming systems in the Mallee region through research, education, and collaboration.

Q60. Does fire create water repellent soil?

Intense fires (>300°C) can increase soil repellence by pushing organic matter deeper, while cooler stubble burns may reduce repellence but at the cost of beneficial

Q51. Why is repellence ‘better’ in wet years?

Soil repellence appears reduced in wet years because increased moisture weakens hydrophobic bonds, allowing water to infiltrate more easily, but repellence returns when the soil

Q53. Why is crop establishment worse on water repellent sand when sown dry?

Crop establishment is poorer on dry-sown water repellent sands because dry sowing disrupts natural water entry paths and funnels more repellent soil into seed furrows,

Q52. How deep is the repellent soil layer?

Water repellent soil typically occurs in the top 10–15 cm, usually strongest between 2–5 cm depth, but can start slightly below the surface in bare

Q55. How do wetting agents work?

Wetting agents reduce water repellence by lowering surface tension (penetrants) and retaining moisture near roots (humectants), with best results from seed-zone application on stable furrows;

Q50. Why do soils become water repellent?

Soils become water repellent when organic compounds from plant residues, animal manure, and microbes coat soil particles, especially under dry conditions that slow their breakdown.
