Detailed Solution

Manure and fertilizers are used in fields to supply essential nutrients to the soil, improve soil fertility, and increase crop production. For healthy crop growth, plants need nutrients like nitrogen, phosphorus, and potassium. Continuous farming makes soil lose its natural nutrients, leading to lower productivity. To overcome this problem, farmers add manure and fertilizers.

What is Manure?

Manure is an organic substance obtained from the decomposition of animal dung and plant waste.
It improves soil texture and fertility naturally.
It is eco-friendly but provides nutrients in smaller amounts.

What are Fertilizers?

Fertilizers are chemical substances rich in nutrients like nitrogen (N), phosphorus (P), and potassium (K).
They are quick in action and help crops grow faster.
Examples include urea, ammonium sulfate, and superphosphate.

Comparison Between Manure and Fertilizers

Manure	Fertilizers
Natural and organic	Chemical and synthetic
Improves soil structure	Supplies nutrients quickly
Eco-friendly	Can cause pollution if overused
