Question: Due to over liming in acid soil, ____ deficiency may occur?
Options:
B (Boron)
Ca (Calcium)
Zn (Zinc)
N (Nitrogen)
✅Explanation:
• While over liming acid soil can potentially affect the availability of several nutrients, boron (B) deficiency is the most commonly observed issue. Here's why:
-Liming increases soil pH: Calcium carbonate (CaCO₃) is the most common liming material, and it raises soil pH as it dissolves.
-Reduced boron availability: At higher pH levels, boron becomes less soluble and less available for plant uptake.Â
