    A Thermodynamic Assessment of the Nutrient Status of Malayan Soils Quantity-Intensity Measurements for Potassium Using Calcium Chloride Equilibriation
    (1968) Mohinder Singh, M.; Tan, K.T.; Pushparajah, E.; Talibudeen, O.
    Quantity /Intensity (Q/I) relationships for potassium status of soils were determined in nine acid soils of Malaya which are known to have widely differing K-status and on which rubber Is commonly grown, by the calcium chloride equilibriation procedure of BECKETT. Quantity. Intensity and Buffer Capacity values derived from these Q/l relationships did not give better relation with the status of soil, as indicated by greenhouse cropping by Pueraria. than the conventional acid-extractable value. The best assessment parameter appeared to be a Buffer Capacity value (B. C. cropping), obtained from greenhouse cropping data and the laboratory measured intensity, although intensity, when taken alone is the poorest Indicator of soil K status as assessed by greenhouse cropping by Pueraria.
