Phosphorous and nitrogen ions generally get depleted in soil because they usually occur as
Options
- ANeutral ions
- BNegatively charged ions
- CPositively charged ions
- DBoth positively and negatively charged but disproportionate mixture
Correct answer
B. Negatively charged ions
Step-by-step solution
Phosphorus is absorbed by the plants from the soil in the form of phosphate ions H 2 PO 4 - and HPO 2 2- , and nitrogen is absorbed by the plants in the form of nitrate ions (NO 3- ). The negatively charged mineral ions can be easily absorbed by the plants because they are not adsorbed on soil particles.
