solo sódico
1. Soil that contains excessive amounts of sodium ions (Na+), typically with a sodium adsorption ratio (SAR) greater than 13, which causes poor soil structure, reduced permeability, and impaired plant growth
The farmer's field became a sodic soil after years of irrigation with saline water.
O campo do agricultor se tornou um solo sódico após anos de irrigação com água salina.
2. A type of degraded soil characterized by sodium accumulation that disperses clay particles and creates a hard, crusty surface layer
Sodic soil management requires the application of amendments like gypsum to improve soil structure.
O manejo do solo sódico requer a aplicação de corretivos como gesso para melhorar a estrutura do solo.
This term is primarily used in technical and agricultural contexts in both Brazil and the USA. In Brazil, soil sodicity is a significant issue in semi-arid regions and areas with high irrigation practices. The term is essential in agronomic discussions regarding soil fertility and land reclamation projects.
