A composition comprising at least one nutrient element, wherein the at least one nutrient element possesses a relative energy-state value greater than the relative energy-state value of the at least one nutrient element in a preexisting state, the composition being effective, perhaps because of the greater energy-state value, to improve the ability of a soil, when combined with the composition, to support plant growth better than the soil, when not combined with the composition. Also a composition comprising at least one nutrient element, wherein the composition possesses an energy spectrum more positive than the energy spectrum of the composition in a preexisting state, the composition being effective, perhaps because of the more positive energy spectrum, to improve the ability of a soil, when combined with the composition, to support plant growth better than the soil, when not combined with the composition. Methods of making and using the same for improving soil, plants, plant growth, seeds, and/or plant products, including quality of plant products, are also disclosed, as well as improved soil, seeds, including quality of seeds, plants, and/or plant products, including quality of plant product.

A vertical ring magnetic separator for de-ironing of coal ash comprises a rotating ring (), an inductive medium (), an upper iron yoke (), a lower iron yoke (), a magnetic exciting coil (), a feeding opening (), a tailing bucket () and a water washing device (). The feeding opening () is used for feeding the coal ash to be de-ironed, and the tailing bucket () is used for discharging the non-magnetic particles after de-ironing. The upper iron yoke () and the lower iron yoke () are respectively arranged at the inner and outer sides of the lower portion of the rotating ring (). The water washing device () is arranged above the rotating ring (). The inductive medium () is arranged in the rotating ring (). The magnetic exciting coil () is arranged at the periphery of the upper iron yoke () and the lower iron yoke () so as to make the upper iron yoke () and the lower iron yoke () to be a pair of magnetic poles for generating a magnetic field in the vertical direction, wherein the inductive medium () is layers of steel plate meshes, each steel plate mesh is woven by wires, and ridge-shape sharp corners are formed at the edges of the wires. A method for magnetically separating and de-ironing of coal ash, utilizes the vertical ring magnetic separator for de-ironing of coal ash. By adopting the vertical ring magnetic separator and the method of magnetic separation for de-ironing, the de-ironing efficiency is improved by at least 20%.
