Question

Compare the manure and fertilizer in maintaining the soil fertility.

Answer 1

Hint: Manure and fertilizer is the type of nutrient which enhances the fertility of soil because the productivity of soil decreases after harvesting one crop after another. Adding the proper amount of manure and fertilizer the yield of crops and fertility of soil both increase.

Complete Answer:
Manure provides the organic matter to the soil which is prepared from the degradation of waste material of animals and plants.
Fertilizer provides the mostly inorganic compound to the soil whose excess amount in soil leads to harmful effects on bacteria as well as on humans.

Sl.no	Manure	Fertilizer
1.	It provides organic material.	It provides inorganic material.
2.	It makes soil productive and fertile.	It also makes soil productive and fertile for a short time.
3.	It enriches the soil with nutrients.	With a long or high amount of fertilizer makes the soil dry and powdery.
4.	It reduces the soil erosion.	It increases the soil erosion.
5.	Manure has no harmful effect on bacteria.	Excess amount of fertilizer leads to death of bacteria which are present in the soil.
6.	It has no effect on the nature of soil.	It changes the nature of soil from acidic to basic.
7.	Slowly absorbed by plants.	Easily absorbed by plants.

Additional information:
- Manure provides organic material which helps to grow the crops by dissolving nutrients in the soil.
- Fertilizer provides the inorganic material which is essential for increase the soil fertility that is nitrogen, phosphorous, calcium, potassium and magnesium

Note:
- Manure and fertilizer both increase the fertility of soil. Manure formed by natural process while fertilizer made by chemical process.
- Normal amounts of fertilizer are very good for soil, because fertilizer is rich in nutrients.
