Phosphorus travels by weathering and sediment, not as a major gas in the air.

From the opening
Phosphorus moves through the world mainly by weathering of rock, uptake of dissolved phosphate, and transport of particles in water and dust. Unlike nitrogen, it has no large gaseous reservoir that serves as the main highway of the cycle. The opening covers weathering releases a little phosphate, why phosphate sticks to particles, and sediment as the main highway.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
