Özet
Calcareous soils are widespread in arid and semi-arid climate regions. It is estimated that these soils constitute more than one-third of the world's surface area. Calcareous soils are characterized by the presence of calcium carbonate (CaCO3) in the parent material and lime deposition. These soils are generally known to have a pH ≥ 7 and above. In general, CaCO3 in calcareous soils can be concentrated in hard layers, called caliche layers, which adversely affect the distribution of plant roots and the infiltration of water. Although these soils are not so bad in terms of plant nutrients, a fixation reaction occurs, which reduces the solubility of elements such as phosphorus (P) and potassium (K) in the soil solution, gradually reducing their availability to plants. This fixation is physical in calcareous soils but chemical in acid soils. Phosphorus fixation is a combination of surface adsorption and precipitation of various calcium phosphate minerals on both clay and lime surfaces. Consequently, the formation or deposition of lime in soils can be an effective method to slow climate change. © 2024 Nova Science Publishers, Inc. All rights reserved.
