The study looked at how different types of wheat plants affect the levels of different forms of phosphorus in the soil around their roots. They found that the amount of inorganic phosphorus in the soil varied between the area close to the roots (rhizosphere) and further away (non-rhizosphere). All wheat plants reduced the levels of inorganic phosphorus, but some did so more than others. The soil close to the roots had more organic phosphorus compared to further away. The researchers used a special technique to separate the soil around the roots from the rest of the soil. This information can help us understand how different wheat plants affect the availability of phosphorus in the soil, which is important for their growth.
