Answer:
B. Calcium nitrate
Step-by-step explanation:
Calcium nitrate is one of the materials that will increase the pH of the soil and make it more alkaline in nature.
Calcium nitrate is helps to increase the alkalinity of soils.
- For a plant to take up nitrate, it must discharge or lose a hydroxyl ion.
- A hydrogen ion is used to take up the nitrate.
- This releases more hydroxyl into the soil than usual.
- Ammonium sulfate reduces soil pH.
