An American high-tech earth soil recovery method, characterized in that, the earth soil contains 108 soil trace elements, comprising the following steps: preparing a powder of nano-particles for the soil trace elements； and spraying the powder into soil infertile, acidified, or contaminated by heavy metals, and through an antagonistic (exchange) effect of the soil trace elements incurred by the powder (electrolyte) potential, the earth soil is recovered, so that in growing a crop, even if the earth soil is contaminated by heavy metals, the heavy metals are not absorbed, and the crop grows by absorbing the added soil trace elements in the soil. Through the inter-molecular antagonism/coordination/absorption/penetration, the earth soil structure is restored, to recover the earth soil for repeated usages, hereby strengthening constitution of a crop, and raising its quality and yield.
