What impact does soil salinity have on plant health?

Soil salinity significantly impacts plant health by leading to moisture stress and inhibiting growth. High salinity levels in the soil create an osmotic pressure that can make it difficult for plants to absorb water, essentially putting them under drought-like conditions even when water is present in the soil. This stress can lead to physiological responses such as reduced photosynthesis and stunted growth, as plants direct their energy towards survival rather than growth. Furthermore, excessive salts can directly affect root development and nutrient uptake, compounding the stress experienced by the plant. Therefore, understanding the effects of soil salinity is crucial for managing plant health and ensuring optimal growth in diverse agricultural and horticultural contexts.
