उत्तर
Yes, it is better to use compost instead of chemical fertilizers. This is because compost is prepared from plant and animal wastes, therefore, it easily gets decomposed. It does not add any harmful chemicals to the soil, whereas an excessive use of chemical fertilizers causes soil and water pollution.
