A system to manufacture a native soil flowable fill onsite includes hydro excavation equipment having a suction hose. In addition, the system includes a plurality of onsite debris tanks, where each onsite debris tank is configured to be coupled separately to the suction hose and to store native soil vacuumed from an adjacent hole at an onsite excavation. The system also includes a mixing apparatus inside each of the onsite debris tanks configured to mix the native soil from the adjacent hole with additional components to form a native soil flowable fill for the respective adjacent hole.

A method for production of a modified clay powder comprises the steps of: a) acquiring batch clay, and b) forming a modified clay powder with an average particle size of between 2 nm and 150 nm. The main groups of clays include kaolinite, montmorillonite, bentonite, smectite, and illite. A method for improving the stability of a soil sample comprises a steps of: a) acquiring the soil sample, b) acquiring a clay, c) forming a clay powder (nano-clay as nano green-additive) with an average particle size of between 2 nm and 150 nm, optionally preparing a suspension of the nano-clay in water, d) mixing the clay powder or the suspension of the clay powder in water with the soil sample in a weight ratio of between 1:100 and 1:1 of the clay powder to the soil sample, respectively, e) applying the mixture obtained in step d) to the required construction site, f) forming the mixture at the construction site in accordance with a predetermined construction project until a structure of predetermined dimensions is obtained, g) exposing the structure obtained in step f) to an amount of water for the curing time. Applying the mixture obtained in step e) to the predetermined construction site can be realized with a method of spraying.

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.
