Select the correct answer using the code given below.
a) 1 and 3
b) 1, 2 and 4
c) 4 only
d) 2 and 3
Answer: (b)
- Statement 1 is correct: Permaculture is a nature-based system that promotes multi-cropping and integrated farming systems. Example: Agroforestry. Chemical farming is more suitable for monoculture cropping due to the use of crop-specific inputs like irrigation, chemical fertilizer, and harvesting methods.
- Statement 2 is correct: Chemical fertilizers will make the soil less fertile over time, which can lead to serious problems like soil salinization. However such problems are not seen in permaculture farming as it relies on organic fertilizers.
- Statement 3 is incorrect: Chemical farming is based on the intense use of inputs like Chemical fertilizers and irrigation that make the soil less fertile over time, thus restricting its practice in semi-arid regions. Thus, conventional farming is not suitable for semi-arid regions.
- Statement 4 is correct: Mulching is an important component of Permaculture systems for promoting maximum efficiency
