How does a low pH level in the soil effect plants?



  1. 0 Votes

    Each plant has its own recommended soil pH value range. The reason for this is that soil pH effects the availability of nutrients within the soil and plants have different nutrient needs. For example the nutrient nitrogen, a very important plant nutrient, is readily available in soil when the pH value is above 5.5. Similarily the nutrient phosphorous is available when the pH value is between 6 and 7. If a plant is placed into the wrong kind of soil it will be lacking in nutrients that it needs which will promote disease. In general the best pH value range for soil is approximately 6 or 7 as this is the range in which most nutrients can be readily available.
