A
organic manure
💡 Explanation:
Plants can neither grow in too acidic conditions nor grow in too basic conditions. Thus for the proper growth of the plant optimum pH of the soil has to be maintained.
If the soil is too basic then it can be corrected by using organic manure. Compost micro-organisms operate best under neutral to acidic conditions with their pH ranging from 5.8 to 8.
Thus they not only help in maintaining the pH of the soil but also increase the nutrient availability and improve the quality of the soil (unlike inorganic chemical fertilizers which damage the soil quality).
Thus organic manure creates acidic conditions, which help in neutralizing the basic soil and makes the pH optimum for plant growth.
Hence, the correct answer is the option (C).
