Which of the following phenomena affects plants growth in an alkaline soil?
Answer Details
Poor drainage affects plant growth in an alkaline soil.
Alkaline soil is characterized by a high pH level, typically above 7.0, which can lead to a variety of problems for plants. One of the major issues is poor nutrient availability, as many essential plant nutrients become less soluble and therefore less available to plants at high pH levels. Poor drainage exacerbates this problem by further reducing the availability of nutrients. When water is unable to drain effectively from the soil, it can become stagnant and oxygen-deprived, leading to anaerobic conditions that are detrimental to plant growth. This can also cause root damage or death, which further limits the plant's ability to take up nutrients and water from the soil. As a result, poor drainage is a major factor that affects plant growth in alkaline soils.
