Chloride ions in irrigation water can have negative impacts on crop growth and soil health. High chloride levels can cause salt stress, reduce plant growth, and increase the risk of foliar damage. Additionally, chloride can accumulate in the soil, leading to soil salinization and reduced soil fertility. Chloride can also react with other soil nutrients, reducing their availability to plants. Monitoring and managing chloride levels in irrigation water is essential to preventing these negative impacts on crop growth and soil health.
