Boosting Soybean Yields and Soil Health: Potassium Fertilizer Breakthrough Transforms Farming in Vertisols
The study looked at how different levels of potassium affected soybean yield and soil nutrients in vertisols. They tested four treatments with varying amounts of NPK fertilizer. Results showed that soil pH, EC, and organic carbon improved the most with 30:75:90 kg NPK ha-1. Available nitrogen, phosphorus, and potassium were significantly increased with 90 kg K2O ha-1 along with the recommended N and P doses.
