प्रश्न
Explain how soil gets affected by the continuous plantation of crops in a field.
उत्तर
Continuous cultivation of crops in the field causes deficiency of some nutrients in the soil, such as nitrogen, phosphorus, potassium etc. Due to which its fertility also decreases. This is the reason why crops should not be grown continuously in the field and the field should be left fallow for some time. Another method is crop rotation, in which farmers grow a different type of crop after one crop, so that nitrogen is replenished in the soil.
