Question

Which of the following may increase the fertility of soil?
(a)Vermicompost
(b)Manure
(c)Industrial waste
(d)Both (a) and (b)

Answer 1

Soil fertility refers to the flexibility of the soil to sustain plant growth. Fertile soil leads to high yield and better quality of plants. Fertile soil is wealthy in fundamental parts and minerals, has fine aeration, water holding capacity, and good texture.

Complete answer:
Vermicomposting is a process during which the earthworms are used to convert organic waste into manure rich in high nutritional content. Vermicomposting turns the kitchen waste and other green waste into dark, nutrient-rich soil. Because of the presence of microorganisms, it maintains healthy soil. Manure is an organic matter obtained from solid animal wastes, used to enhance the soil quality and increase the yield of healthy crops. Manure is very rich in organic matter and humus and thus improves the soil fertility. Therefore, both vermicomposting and manure are utilized in the sector to extend the fertility of the soil.

Additional information:
Millions of factories, mills, industries, mining plants, etc. around the world. These industries use raw materials to supply finished goods for consumers. But within the manufacturing process, there are materials which are rendered useless. They constitute an economic waste. Some samples of industrial wastes are metals, paints, etc. Industrial waste is often categorized into biodegradable and non-biodegradable.
The advantages of Manure are-
-These are an honest source of macronutrients.
- Improves soil fertility.
- Reduces erosion and leaching.
-Improves the physical properties, water, and nutrient holding capacity of the soil
- It is often transported easily.
- Methane gas is a by-product of manure and can be used for cooking and heating purposes.
-The crops grown on the land treated with manure produce healthy crops.
The advantages of vermicomposting are-
1. Develops the roots of the plants.
2. Improves the body of the soil.
3. Improves the fertility and water-resistance of the soil.
4. Assist in germination, plant development, and crop yield.
5. Nurtures soil with plant growth hormones like auxins, gibberellin, etc.

So, the correct answer is ‘Both (a) and (b).
Note: Vermicomposting is an eco-friendly process that recycles organic waste into compost and produces valuable nutrients. Manure is environment-friendly and has contributed an excellent deal in increasing food production. trash forms the simplest manure just in case of gardening. It also acts as a nutrient-rich fertilizer when it becomes compost and applied to crops.
