La solución extractora y la humedad en relación con el potasio intercambiable. Experiencias en un suelo aluvional de Costa Rica

Studying the exchangeable potassium in an alluvial sandy loam soil, derived from recent volcanic materials, on air drying and oven drying, potassium fixation was observed. Normal ammonium acetate solution was found a more efficient extractor than Morgan's solution. Liming increased exchangeable pota...

Summary:Studying the exchangeable potassium in an alluvial sandy loam soil, derived from recent volcanic materials, on air drying and oven drying, potassium fixation was observed. Normal ammonium acetate solution was found a more efficient extractor than Morgan's solution. Liming increased exchangeable potassium. A high field capacity and an unusually high amount of water in the air dried soils are reported.
