Hidden Soil Phosphorus Fuels Future Farming
19 Jun
Summary
- New method simplifies measuring DNA-bound phosphorus in soil.
- DNA-bound phosphorus is linked to microbial activity.
- Findings may improve soil fertility and sustainable agriculture.

Researchers have uncovered new details about DNA-bound phosphorus, a biologically active form of the nutrient found within living soil microbes. This discovery is critical for efficient nutrient management in agriculture, especially with growing populations and finite phosphorus reserves.
A simpler, more cost-effective method has been developed to measure this DNA-bound phosphorus. This technique provides fresh insights into how phosphorus moves through soils, potentially enhancing soil fertility and supporting sustainable food production systems.
The study revealed that DNA-bound phosphorus concentrations correlate strongly with soil pH and microbial biomass. This suggests that this phosphorus is part of a dynamic microbial ecosystem, not a stable underground reserve.
Understanding how microorganisms store and recycle phosphorus could lead to improved farming practices. This includes better soil fertility management, reduced fertilizer losses, and lower environmental impacts, contributing to overall environmental sustainability.
