Question

Why are manure and fertilizers used in fields?

Answer 1

Hint: Manure and fertilizers. Manuring is the process of addition of natural or chemical sources of nutrients for the crop. Fertilizers are used to increase the productivity of crops.

Complete Answer:
- Manure is the natural fertilizer free from synthetic chemicals. Manure is made from decomposing plant’s parts and animals waste. Therefore, it is rich in nitrogen, phosphorus, potassium and other nutrients.
- All these nutrients are essential for plant growth, thus using manure as fertilizers in fields provide crops with all required growth factors.
- Manure also contains different types of microbes that improve the fertility of soil by improving its organic content.
- Manure is the natural substance obtained by the decomposition of plant and animal remains by bacteria. It provides humus to the soil and is less rich in plant nutrients. The manure can be prepared in fields and they are inconvenient to store and transport.
- The manure is slowly absorbed by plants. The fertilizers are inorganic substances or compounds. They do not provide humus to the soil. The fertilizers are rich in plant nutrients such as nitrogen, phosphorus and potassium.
- The chemical fertilizers are prepared in factories. They are easy to store and transport. Fresh manure breaks down faster than composted manure. Not all manure provides nutrients to plants.
- As it breaks down, manure containing a lot of bedding takes nitrogen from the soil. This reduces the amount of nitrogen available to plants and applying too much synthetic fertilizers can “burn” foliage and damage your plant.
- Six primary nutrients are carbon from $C{O_2}$ in the air, hydrogen from water, oxygen from water and air, nitrogen helps plants make the protein phosphorus and potassium are main nutrients.

Note: Stored manure is often referred to as ‘’rotted manure’’. It has no unpleasant smell, and its texture has changed since it was produced. Remember that is possible if we over-apply organic matter of any kind.
