Poet Kazi Nazrul Islam wrote “The soil of my land is richer than pure gold”. Truly, the soil of Bangladesh is more pure than gold. The fertility of this soil was once a matter of wonder. The silt deposited from the rivers used to expedite the cultivation of crops. However, at present it is us who have polluted the soil and in turn have reduced its fertility. Chemical fertilisers are being used in the fields to produce more food for an ever-growing population across the country. And, excessive tilling has caused the land to become unfertile and lose its organic characteristics.
