Answer:

(i) Excessive use of urea (fertilizer) poisons earthworms and it leads to their death (earthworms) and soil acidification.

(ii) Modern agriculture implements save time, labour and energy. And the benefits will be much more than crops grown using traditional methods.

(iii) 2,4-D Ethyl ester, Neem extract, Glyphosate are three commonly used wedicides. Farmers must cover their mouth and nose while spraying wedicides because it can be harmful to them.
