inorganic acceptors.
In light of the above statements, choose the correct answer from the options given below.
Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Application of lime resulted in reduced adsorbed and solution Al", thereby, Al toxicity potential is greatly
reduced and increases yield potential
Reason (R) : When lime is added to acid soils, exchangeable and solution Al? is reduced by precipitation as Al(OH), with an
increase in soil pH
In light of the above statements, choose the correct answer from the options given below.
