Phosphate rocks and partially-acidulated phosphate rocks as controlled release P fertilizers

  • Published:
Fertilizer research Aims and scope Submit manuscript

Abstract

Properties of phosphate rocks (PRs) and partially acidulated phosphate rocks (PAPRs) which affect the pattern of P dissolution and thus the potential for manipulating the rate of P release are reviewed. The effects of soil and plant properties are also considered.
