Nutrient Releasing Mechanism and duration	It supplies nutrients to the plants faster and with in a short period	It supplies nutrients to the plants very slow and take long period due to slow decomposition of organic material.
Farmer Point of View	It gives more yield and immediate supply of nutrients to the plants.	It increases soil fertility and slowly supplies nutrients to the plants.

 Conclusion:

Both manure and fertilizer aim to nurture healthy soil and thriving plants, their methods differ in their function. So, many farmers and gardeners use a combination of both fertilizers and manure to optimize or to increase soil health and plant productivity by reducing environmental impacts.
