The Cost of Inaction in Victorian Agriculture: A Closer Look

Victorian beef and lamb producer Andrew Freshwater shares valuable insights and financial implications drawn from a model farm in Northeastern Victoria. A ‘do nothing’ fertiliser and soil improvement strategy has cost the business an alarming $3.13 million over several years.

Understanding Inflation’s Impact

Producers must not fall into the trap of relying on 2022 prices as a benchmark in 2026. The Producer Price Index (PPI) for agriculture has significantly outpaced general inflation since January 2022.

• The Adjustment: Cumulative inflation has reached approximately 21.4%.
• Purchasing Power: $1.00 in 2022 now equates to roughly $0.79 of the same goods.
• The Inaction Fallacy: Skipping fertiliser could seem like a $54,000 annual saving, but inflation has eroded this cash value, making it a poor choice in the long run.

Victorian Farm Monitor Project (VFMP) Insights

Data from the Livestock Farm Monitor Project (LFMP) highlights how, despite efforts to cut variable costs, Fixed Overheads have become a troubling burden on cash flow.

• 2022 Fixed Overheads: Approximately $76.50 per hectare
• 2026 Fixed Overheads: Approximately $118.00 per hectare (an increase of 54.2%)
• The Mechanics: Costs related to rates, insurance, power, and compliance apply regardless of production levels.

In our model of a 714-hectare farm, the cost of merely existing rose from $54,621 to $84,252. A decline in stocking rates led to a doubling of overhead costs per animal, resulting in increased operational expenditures without any additional productivity.

The Regenerative Agriculture Perspective

Nutrient Export Reality

Proponents of Regenerative Agriculture often suggest that biological practices can replace mineral inputs. However, this view contradicts the Law of Conservation of Mass.

For every 450kg steer that leaves the farm, minerals are physically exported:

• Phosphorus (P): 3.2kg
• Nitrogen (N): 11kg
• Calcium (Ca): 6.5kg

For an enterprise with 10,000 DSE, this equates to about 10,000kg of elemental Phosphorus exported annually.

The Manure Fallacy

To substitute that 10,000kg of Phosphorus with manure (which contains roughly 0.6% Phosphorus), one would need to:

• Spread 2,333kg of dry manure per hectare.
• Maintain 21 DSE/ha throughout the year.

Yet, to support 21 DSE/ha, the farm must produce 11,500kg DM/ha, whereas an unfertilised North East Victorian farm yields only 4,500kg DM/ha. Thus, the logic fails; doing nothing is merely extracting resources without replenishing them.

Aluminium Levels and Soil pH

Soil Acidification

In granitic soils, soil acidifies at a rate of approximately 0.05 pH units per year under grazing conditions.

• The Threshold: Al becomes soluble when pH (CaCl2) drops below 4.8.
• Toxicity: Soluble Al acts as a root-tip poison, inhibiting cell division.

By 2026, the ‘Do Nothing’ model shows soil pH declining from 5.1 to 4.9, with Aluminium levels exceeding 15%. Roots that should reach 1.2 metres are now stunted at 10cm. During hot weather, plants with limited root systems die while those with deep roots continue to access sub-soil moisture.

The Consequences of Poor Animal Growth Rates

Average Daily Gain (ADG) Concerns

One of the most significant costs of inaction is the detrimental shift in the botanical composition. Declining Phosphorus levels lead to a loss of Clover, a crucial protein source.

• Weed Proliferation: Silver Grass and Capeweed take over, causing animal growth to plummet.
• The Energy Gap: Steers that once gained 1.2kg/day now struggle to reach 0.4kg/day and even lose weight in winter.

Following this maintenance feed-only state, the model farm incurs $84,252 in fixed overheads for animals that are not growing, leading to a low-productivity system.

Where is the Revenue Going?

The Real Cost of Poor Decisions

Choosing to save money for years has ultimately led to a significant loss of value:

• The Revenue Gap: An opportunity cost of $2,114,819. The farm could have produced 1.5 million kilograms more beef had it maintained a competitive Average Daily Gain.
• The Asset Restoration Cost: Estimated at $523,005, this bill includes:
• Capital Lime: $196,350
• Capital P: $98,175
• Pasture Re-sowing: $199,920
• Labour Opportunity Cost: With a farm manager’s time valued at $100,000 per year, five years of inaction cost the farm $500,000 in unpaid labour.

Understanding Soil Types

The effects of inaction vary across different soil types on the model farm, which is likely managing three distinct soil profiles:

The Granitic Uplands

These lightweight sandy loams are chemically fragile:

• Low Cation Exchange Capacity (CEC) leads to rapid nutrient loss.
• Acidifies quickly, resulting in aluminium toxicity.

The Sedimentary Slopes

These soils contain buckshot gravel, which ties up Phosphorus:

• They appear green in the short term, often dominated by non-nutritive plants.

The Alluvial Flats

Heavier soils near creek lines can initially mask the impact of neglect:

• Because they are more productive, the opportunity cost of underutilizing these areas is significantly higher.

A Decade of Consequences: 2022–2032

The cost of inaction must be projected into the coming decade to reveal the complete financial picture:

• Maintenance Model (14 DSE/ha): Steady revenue and manageable costs lead to a net profit of $4.8 million over ten years.
• Do Nothing Model: Initial savings don’t last beyond Year 2; production drops 40% by Year 5, resulting in $1.2 million in losses over ten years.

The Health of Livestock & Genetic Impacts

In a neglectful system, the model farm not only fails to produce quality meat but also suffers from genetic erosion:

• Heifer Development Crisis: With diminished weight gain due to nutrient deficiencies, conception rates could plummet from 92% to 74%.
• Trace Mineral Deficiency: Lower availability of essential nutrients leads to increased veterinary costs and health concerns.

Getting Back on Track

For those managing a depleted farm, a structured restoration plan is critical:

Step 1: The Lime Application (Months 1–6)

• Neutralise Aluminium toxicity by applying 2.5t/ha of high-neutralising value Lime.
• Goal: Raise pH from 4.8 to 5.2 for optimal root development.

Step 2: Phosphorus Restoration (Months 6–12)

• Apply a capital use of 250kg/ha of Single Super to stimulate Clover growth.

Step 3: Genetic Over-Sowing (Year 2)

This is an ideal time to introduce more resilient varieties like Holdfast GT Phalaris, enhancing pasture productivity.

Between 2022 and 2026, the model farm faced a critical choice: prioritize sustainability over flawed cost-cutting measures. The ultimate cost of inaction totaled $3,137,824, serving as a cautionary tale for the agricultural community. As the Southern Oscillation Index reveals further climatic challenges, maintaining high-fertility, resilient systems will determine survival and profitability in the coming years.
