Magnesium deficiency most commonly occurs in acid, sandy soils in areas of moderate to high rainfall.

Taking the aqueous sandy soil in hot summer and warm winter area as a heat transfer medium, studies the influence of seepage on heat transfer characteristics of the soil by a simulating experiment.

The soil were divided into five groups of soil, e, g, light clay, heavy loam, medium loam, light loam and sandy soil, using the group of soil texture of plowed layer as the mapping unit.
