The Initial and Residual Value of Phosphorus from Apatite Rock Phosphates and Superphosphates as Measured by 32p Dilution Technique

A pot trial using maize (Zea mays, L.) grown on an Ultisollabelled with 32p was carried out to evaluate the agronomic value of nine types of apatite rock phosphates and triple superphosphate. Results show that the effectiveness of tested rock phosphates is variable as compared to superphosphate, w...
