Which of the following nutrients is available at neutral pH value?
Answer & Solution
Correct Answer:
Option
D
Phosphorus is the nutrient available at a neutral pH value. Soils with pH values between 6 and 7.5 are ideal for phosphorus availability, while pH values below 5.5 and between 7.5 and 8.5 limits phosphorus availability to plants due to fixation by aluminium, iron or calcium.
