The results show that there is a linear correlation between magnetic susceptibility and density. Take 1.6 g/cm^3 as a boundary value, the magnetism of high density coal and low density coal was opposite. The diamagnetism property of low density coal weakens and the paramagnetism of high density coal enhances along with the size reduction of fine coal. The magnetic field intensity influences the magnetism of coal.

The inhibitive effect of 1, 2-benzenedicarboxylic acid on the absorption of N, P and K increased with its concentration rising. Low concentration of dibutyl phthalate increased the absorption of N, but decreased the absorption of P and K. Its high concentration restrained the absorption of N, P and K, while the low concentration of diphenylamine could stimulate the absorption of N and K, but restrain the absorption of P.
