MCQ (Single Correct) +4 −1
Which nutrient is often a limiting factor in agricultural production?

  • Carbon: Readily acquired by plants from atmospheric carbon dioxide ($CO_2$) during photosynthesis and is not a soil-supplied mineral limiting nutrient.
  • Oxygen: Absorbed freely from air and soil pore spaces during root respiration and is not a limiting mineral fertilizer element.
  • Hydrogen: Supplied in abundant quantities through water ($H_2O$) absorbed by roots during transpirational uptake.
