Answer 1

Hint: Preparation of organic fertilizers is very important for reducing soil pollution and increasing the fertility of the soil with environmental friendly products. The chemical fertilizers are very harmful to the soil and even to the plant and human health.

Complete Answer:
- To solve this question, we have to know about compost. Compost is the organic matter used as a fertilizer in cultivational fields. To produce, compose the organic matter and undergo the decomposition process and form the composting.
- The organic matters like vegetable wastes, husk, and cow dung are used to undergo composting. It is useful for the plants as it is rich with high nutrients. Depending on the pile size of the compost it will take different time to produce fertilizer but minimum it takes three month maximum two years.
- Healthy items to compost involve vegetable peelings, teabags, fruit waste, cutting grass, and pruning of plants. These are rapidly break-down and give substantial nitrogen as well as humidity. Having items like egg boxes, cardboard, fallen leaves, and scrunches paper are good too.
- Now, in vermi- processing worms and human excreta are used mostly in the soil as manure and fertilizers as they help in the growth of plants by providing the essential nutrients. It is beneficial when compared to fertilizers as they contain chemicals which sustain in the soil, degrading its quality. Also, chemicals in fertilizers run away with water causing water pollution.

Hence, the correct option is ‘a’. Redworm.

Note:
- Worms are also used for preparing vermi-compost in which certain earthworms’ species are used to enhance the conversion of organic wastes to produce good fertilizer.
- Vermicomposting can be carried out in two methods; bed methods in which beds of different organic matters are being prepared and the pit method in which the organic matters are dumped inside a cemented pit along with the worms and left for decomposing.
- But the pit method has some disadvantages as it has a water logging problem and poor aeration.
