Abstract

A permanent magnet moulded with a water-soluble binder is embedded in soil to accelerate plant growth. It then disintegrates to a powder in the presence of water to act as a fertilizer. The magnet may be of iron, Co-Fe ferrite, or Mn-Bi alloy. A deliquescent material, e.g. Mg, Ca, or Fe chloride, may also be incorporated.ALSO:Plant growth is accelerated by use of a permanent magnet moulded with a water-soluble binder, which disintegrates in the presence of the water in the soil. The magnet may be of iron, Co-Fe ferrite, or Mn-Bi alloy. A deliquescent material, e.g. Mg, Ca, or Fe chloride may also be incorporated. In the experiments described, the growth of radishes and lettuce was investigated with and without magnets, and with the magnet at different depths in the soil. A citrus grafting was also carried out.
