A new grading system for plant-available potassium using exhaustive cropping techniques combined with chemical analyses of soils
A new grading system for plant-available potassium (K) in soils based on K release rate from soils and plant growth indices was established. In the study, fourteen different agricultural soils from the southern subtropical to the northern temperate zones in China were analyzed by both chemical extra...
