In a five-year trial reported in 2025, scientists mixed discarded oyster shells into acidic farmland; peanut yields rose by up to 37%

Researchers repurposed oyster shell waste to improve sour farmland in China. This five-year trial significantly boosted peanut crop yields by up to thirty-seven percent. The soil's acidity decreased, and toxic metal uptake was reduced. This innovative approach addresses waste and enhances agricultural productivity simultaneously. Such low-cost, circular farming methods are crucial for global food security.
