Soil phosphorus - The basics

Phosphorus (P) is a major element (macronutrient) that plays a number of important roles in plants, such as productivity, crop quality, increased root growth, and earlier crop maturity. It is necessary for proper cell division and formation of new cells. It's important that soil P is managed correctly for crop nutrition.

This fact sheet covers the common characteristics of soil P and its availability for uptake by plants such as pH, mobility and microbial activity, and provides practical management tips and tools in line with the ‘4Rs’ - right source at the right rate, right time, right place.
