Write the different between Fertilizers and Manure with examples
Answers
→Answer :
• Manure :
Manure is an organic substance that is obtained from decomposition of vegetables and animal waste.
Manures are relatively less rich in plant nutrients, they only remove general deficiency of soil.
They add humus to soil by providing organic substances and nutrients.
The addition of manure to soil does not require any special guideline
Manure is not readily soluble in water thus it is absorbed by plants slowly.
•Fertilizers :
Fertilizers are inorganic substances manufactured in factories.
Fertilizers are very rich in plant nutrients like NitrogenN, Phosphorus P, Potassium K.
They ensure healthy growth and development of plants by providing nutrients however lack to add humus to soil.
The addition of fertilizer to soil requires special guidelines like dose time and post addition precautions should be followed to avoid mineral toxicity.
Fertilizers are readily soluble in water thus are rapidly absorbed by plants.
