Unlike fertilizer, the exact composition and chemical composition of soil reforming depend on the source, and soil permeability and water retention characteristics can be improved by using a soil preparation. Impaired soils are usually poorly vegetated, poorly structured, hindered plant root growth, low fertility, or lack of nutrients (unbalanced, acidified, salinity, excessive or insufficient soil moisture, toxic substances, etc.). Obstacle soils include sandy soil, clay soil, structural obstacle soil, acid soil, saline soil, alkaline soil, and contaminated soil ( Contaminated soil), etc.

  • Sandy soils are mainly found in dry areas and appear in soils undergoing desertification. In dry areas, the soil is eroded by wind or the soil is eroded by concentrated rainfall, so the survival rate of planted water is low. It is difficult to form a forest or grassland because the roots of plants such as trees or grass cannot use not only water but also nutrients.
  • Inorganic salts such as MgCl 2 can retain moisture in the soil, but in particular, in sandy soils, they are easily dissolved by rain and are easily removed from the soil. . In addition, the use of an excessive amount of inorganic salt may cause environmental problems such as soil acidification and plant death.
