Chinese researchers have discovered the optimal conditions for growing blueberries, which require high levels of organic matter and a specific soil pH level. The study found that the best results were achieved when peat treatment was combined with acidified rice husk, which provided the greatest beneficial microbial diversity and brought the soil pH to 5.53. This could be an alternative to sulfur fertilizers in practical production. Furthermore, husk with an organic matter content above 8.50% is most suitable for blueberry growth, with the ideal soil having an organic matter content of 8-12%.
