The soil becomes toxic to plants when the concentration of its essential elements is in the range labelled

Answer Details

The soil becomes toxic to plants when the concentration of its essential elements is in the range labelled IV. In soil, there is an optimal concentration range of essential elements that supports plant growth and development. When the concentration of essential elements exceeds the optimal range, it can become toxic to plants and adversely affect their growth and survival. The range labelled IV refers to the concentration range where the essential elements become excessively high, resulting in toxicity for plants. Therefore, it is important to maintain the optimal range of essential elements in the soil for healthy plant growth.
