Fertilizers are substances added to soil to provide essential nutrients for plant growth.
The three primary nutrients in fertilizers are Nitrogen (N), Phosphorus (P), and Potassium (K).
Nitrogen is important for the growth of leaves and stems in plants.
It helps in the production of chlorophyll, which is essential for photosynthesis.

Phosphorus is required for the development of roots, flowers, and fruits.
It plays a vital role in energy transfer within the plant.
Potassium strengthens plants and improves their resistance to diseases and drought.
It also helps in the synthesis of proteins and starches in plants.

Common nitrogen fertilizers include urea, ammonium nitrate, and ammonium sulfate.
Phosphorus fertilizers include superphosphate and ammonium phosphate.
Potassium fertilizers include potassium chloride, potassium sulfate, and potassium nitrate.
Balanced use of NPK fertilizers ensures healthy and high-yielding crops.

Excessive use of fertilizers can harm the environment and reduce soil fertility.
It can cause water pollution through runoff into rivers and lakes.
Farmers are encouraged to use fertilizers based on soil testing for best results.
Organic fertilizers like compost and manure can also supplement nutrients naturally.

Modern agriculture relies on NPK fertilizers to meet the growing food demand.
Proper use of fertilizers promotes sustainable farming and protects the ecosystem.
