Na
Definition: Na
Na: symbol for sodium. Sodium, though not a primary nutrient, can influence soil structure and water infiltration. High sodium levels can lead to soil compaction and reduced water permeability, negatively affecting plant growth. Farmers can benefit from monitoring and managing soil sodium levels through soil testing and adopting practices like gypsum application or crop rotation with salt-tolerant species. This helps maintain soil health, improves crop performance, and ensures sustainable land use.
