"Global Crop Yields at Risk Due to Potassium Depletion in Soil"
A study published in Nature Food reveals that potassium deficiency in agricultural soils poses a significant threat to global food security, with more potassium being removed from soils than added in many regions. This depletion can inhibit plant growth and reduce crop yields, affecting food supplies for millions of people. The researchers recommend policies and practices to address this issue, including global assessment of potassium stocks, monitoring and responding to price fluctuations, sustainable application practices, and intergovernmental cooperation to develop global policy coordination.
