How is permaculture farming different from conventional chemical farming?
1.Permaculture farming discourages monocultural practices, but in conventional chemical farming, monoculture practices are predominant.
2.Conventional chemical farming can cause an increase in soil salinity, but this phenomenon is not observed in permaculture farming.
3.Conventional chemical farming is easily possible in semi-arid regions, but permaculture farming is not so easily possible in such regions.
4.The practice of mulching is very important in permaculture farming but not necessarily so in conventional chemical farming.
Select the correct answer using the code given below:
Explanation
Permaculture farming promotes multi cropping and integrated farming systems, whereas chemical farming is more suitable for monoculture cropping due to use of crop specific inputs like irrigation, chemical fertiliser and harvesting methods. Hence, 1 is correct.
Chemical farming makes the soil less fertile over time due to use of chemical fertilizers, which can lead to serious problems like soil salinisation. Hence, 2 is correct.
In case of chemical farming, intense use of chemical fertilizers and irrigation make the soil less fertile over time, thus restricting its practice in semi-arid regions. Thus, conventional chemical farming is not suitable for semi-arid regions. Hence, 3 is not correct.
Mulching is an important component of permaculture farming for promoting maximum efficiency. Whereas, conventional chemical farming does not consider it as essential. Hence, 4 is correct.
Therefore, option (b) is the correct answer.
