Research question

The manuscript asks whether conventional perpetual-growth assumptions used in discounted cash-flow valuation remain economically defensible when the physical, technological and ecological conditions of a fertilizer business are incorporated into the terminal state.

Core finding

The evidence supports neither a uniform positive perpetual-growth convention nor a universal ecological zero-growth rule. A defensible terminal state must distinguish nominal cash-flow growth from physical fertilizer throughput and reconcile growth with reinvestment, incremental returns, margins, asset replacement, transition requirements, competitive fade and geography-specific ecological internalization.

Sector findings

The study finds materially different constraint structures across fertilizer nutrients. Nitrogen is principally exposed through energy, carbon and downstream reactive-nitrogen effects. Phosphate combines biological non-substitutability with concentrated mineral supply, quality and pollution issues, while current aggregate reserves do not support an imminent-exhaustion conclusion. Potash is more strongly shaped by concentration, geopolitics, logistics, project economics and local mining impacts than by a nitrogen-like global ecological boundary.

Geographic implication

Mature, high-use regions and nutrient-deficit regions require different terminal narratives. Efficiency-driven demand moderation can be material in mature systems, while low nutrient access and soil depletion in other regions prevent a universal assumption that physical fertilizer demand must decline everywhere.

Method

The manuscript uses an interdisciplinary critical synthesis across corporate valuation, ecological economics, agronomy, industrial technology, mineral-resource economics, regulation and financial reporting. It distinguishes directly observed evidence and established scholarly interpretation from analytical inference, hypotheses, assumptions and unresolved evidence gaps.

Research significance

The proposed stable-state framework treats ecological conditions through the financial channel they actually affect—such as demand, price and mix, operating cost, transition capital, asset life, incremental returns, working capital or financing risk—rather than applying a generic ESG adjustment or forcing every ecological effect into the perpetual growth rate.
