Question

Repeated use of sodium nitrate fertilizers increases the alkalinity of the soil.

• A. True
• B. False

Answer 1

The correct option is A

Repeated use of sodium nitrate fertilizers increases the alkalinity of the soil. If soil pH is greater than 7, then the availability of iron, manganese, zinc, copper, and cobalt is reduced, resulting in the reduction of nutrient uptake and foliage production.
