摘要: Summary Soluble phosphorus was allowed to age in contact with four colliery shales for up 6 months. The ageing process apparently involved three stages–(i) a rapid initial drop controlled by pH; (ii) steady-state period; and (iii) an exponential decline whose rate proportional buffering capacity. Using this relation-ship model derived predict soil requirement.
