The heat cured sand of Al-Mg-B compound phosphate inorganic binder was modified by ultrasonic oscillation to binder and adding organic polymer YPPJ while mixing of sand.
On the process of vacuum-deposited Al on organic coat, the film quality is affected dy gases from the organic volatile matter and water vapour in the coat.
Applying organic chemical fertilizer decreased significantly exchangeable al in soil, increased soil nutrients content, and kept the high and stable yield of crops.
