At the heart of agroecology is the idea that agroecosystems should mimic the biodiversity levels and functioning of natural ecosystems. Such agricultural mimics, like their natural models, can be productive, pest-resistant, nutrient conserving, and resilient to shocks and stresses. In ecosystems there is no ‘waste’, nutrients are recycled indefinitely. Agroecology aims at closing nutrient loops, i.e., returning all nutrients that come out of the soil back to the soil such as through application of farmyard manure. It also harnesses natural processes to control pests and build soil fertility i.e., through intercropping. Agroecological practices include integrating trees with livestock and crops. Consider the following: 1. Cover crops 2. Fertigation 3. Hydroponics 4. Mixed farming 5. Polyculture 6. Vertical farming Which of the above farming practices can be compatible with agroecology, as implied by the passage?

Explanation

"implied by the passage" is same as "inferred". Agroecology focuses on natural solutions and mimicking nature. We know the following broad definitions of these words - Fertigation is a method of fertilizer application in which fertilizer is incorporated within the irrigation water by the drip system. This is not seen in nature. Hydroponics is the technique of growing plants using a water-based nutrient solution rather than soil. Again, not mimicking nature. Vertical farming is the agricultural process in which crops are grown on top of each other, rather than in traditional, horizontal rows We can remove these artificial methods and remaining options are answer ie 1, 4 and 5
