List two differences between Manures and Fertilizers.
Answers
Answer:
The difference between manure and fertiliser can be drawn clearly on the following grounds:
Manure can be described as an organic material prepared by decomposition of crop residue or animal excreta, that can be added to the soil to improve its fertility. Unlike, fertilizer is described as any substance (organic or inorganic), that is added to the soil, increase the yield of crops.
The manure is prepared in the field, by dumping the animal and plant waste in open pits, to decompose it. Conversely, fertilizers are produced in factories through the chemical procedure.
As manure is generated out of the decayed plant and animal waste, it provides humus to the soil, which increases the water holding capacity of the soil. Unlike, fertilizer does not provide humus to the soil.
Manure is not as much rich as fertilizers in terms of plant nutrients, as fertilizers are rich in plant nutrients.
As manure is insoluble in water, it is slowly absorbed by the soil. On the other hand, fertilizers get easily dissolved in water, and that is why it is used by the plants immediately.
While manure is economical, as it can be prepared by farmers themselves, fertilizers are industrially manufactured chemical; it is costly.
Manure does not cause any harm to the soil; in fact, it raises the quality of the soil in the long run. In contrast, use of fertilizer in excess can decrease the effectiveness of the soil, as well as it causes harm to the organism present in the soil.
