Phosphorus in Fertilizer: Root Growth, Soil pH, and Environmental Impact

Role of Phosphorus (P)

• Essential for root development and energy transfer.
• Part of macronutrient trio N-P-K (traditionally 3-1-1 ratio).
• Affects soil pH, which controls nutrient availability.

Environmental Concern

Excess phosphate runoff pollutes waterways. Modern regulations limit P in fertilizers; organic compost provides balanced, slow-release P naturally.

Phosphorus is vital but must be managed responsibly.
