New Soil Test Reveals How Microbes Help Feed Plants

Topic: Environment

Scientists have developed a new way to measure phosphorus in soil. This will help us understand how microbes in soil help plants grow and use nutrients.

Phosphorus is an essential nutrient for plant growth, but the world's natural reserves are limited. To maintain fertile farmland and reduce waste, scientists need to understand how phosphorus moves through ecosystems.

A team of international researchers has created a simpler and less expensive way to measure DNA-bound phosphorus (DNA-P) in soils. This form of phosphorus is connected to living microorganisms and can offer insight into the biologically active portion of the soil phosphorus cycle.

The researchers tested and modified an existing analytical procedure, then applied the improved version to 32 different soil types from across the United Kingdom. They found that eliminating enzyme treatments made the method easier and cheaper while still preserving precision and sensitivity.

Why It Matters

This new test will help Indian farmers use phosphorus more efficiently, reducing waste and environmental damage. It will also support sustainable farming practices and contribute to food security in India.
