Answer 2

Explanation:

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.It protects the environment and helps in recycling farm waste.

While Fertilizers are very rich in plant nutrients like Nitrogen, Phosphorus, Potassium. 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.Its excessive use causes water pollution and can not replenish organic matter of soil.
