mention the modern farming method and explain their drawbacks
Answers
Modern farming methods refer to the agricultural production system characterized by the high inputs of capital, labour, heavy usage of farm machinery such as threshers, harvesters, winnowing machine, heavy usage of technology such as selective breeding, pesticides, chemical fertilizers and insecticides.
Drawbacks of modern farming methods :-
1) Modern farming generally includes the use of chemical fertilizers which results in decrease in soil fertility year by year.
2) About half of the nitrate in chemical fertilizers used on crops is dissolved by the rain. The dissolved nitrate runs off the fields to contaminate water courses.
3) Where repeated deep ploughing is done to turn over the ground, heavy rains can carry away the top fertile layer of soil and leave the ground useless for cultivation.
4) Where stubble is being burnt, large amounts of potentially useful organic matter disappear into the sky in the form of clouds of polluting smoke.
5) As water resources are limited, the modern farming methods need excessive use of water that will ultimately lead to water shortage.
6) Use of modern technology also results in killing of various useful micro organisms in the soil needed for healthy growth of crops.
7) Due to the excessive use of chemical fertilizers, we are having intoxicated crops which is very harmful for us.
8) With mechanization in agricultural sector, the farming work force is getting steadily replaced by the machinery, leading to the unemployment and poverty.
Modern farming methods involve the use of high-yield variety seeds. These seeds require a combination of chemical fertilizers and pesticides, agricultural implements like tractors and proper irrigation facilities like electric tubewells to produce the best results. All these elements are manufactured in Industries.
It's main drawback is that it leads to pollution and unemployment.
