Why can adding organic matter improve highly basic soil?
Answer and explanation
Correct answer: It can slowly provide a mild acidic effect and improve balance
Highly basic soil has a pH above the range preferred by many crops. Organic matter decomposes through microbial activity and may release organic acids and carbon dioxide, producing a gradual moderating effect rather than an instant chemical change. This can improve nutrient availability and soil condition. Therefore option A is the best answer; the remaining choices are chemically incorrect or exaggerated.
