Answers
Answer:
(d) Fertilizers are environment friendly.
Explanation:
fertilizer are not environment ffriendly
Fertilizers are added to crops in order to produce enough food to feed the human population. Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and to produce more food. Nitrogen in particular is an essential nutrient for the growth of every organism on Earth. Nitrogen is all around us and makes up about 78% of the air you breathe. However, plants and animals cannot use the nitrogen gas in the air. To grow, plants require nitrogen compounds from the soil, which can be produced naturally or be provided by fertilizers. However, applying excessive amounts of fertilizer leads to the release of harmful greenhouse gases into the atmosphere and the eutrophication of our waterways. Scientists are currently trying to find solutions to reduce the environmentally harmful effects of fertilizers, without reducing the amount of food we can produce when using them.
The incorrect sentence is d) fertilizers are environment friendly.

- Fertilizers are synthetically manufactured in factories. It harms the beneficial microbes present in the soil and also decreases soil fertility if used for a long time.
- Manures and fertilizers help in conserving and developing the fertility of the soil. Fertilizers are not environmentally friendly.
- Manure adds nutrients to the soil without affecting the soil and plant. It does not affect the crops and produces healthy plants.
- Manure provides humus to the soil. Humus is the product of the decomposition of leaves and animal wastes.
