Rock Phosphate Availability as Influenced by Soil pH 1
Abstract. The influence of the pH of the culture medium on the availability of rock phosphate to oats was investigated by means of two sets of pot cultures. In one set, quartz sand containing 1% of montmorillonite clay served as the culture medium. Samples of the clay, previously saturated with H+, were treated with varying.
