What Are Fertilisers?

Fertilizers, either natural or synthetic, are crucial for plant growth as they replenish essential nutrients in the soil. Historically, as agriculture developed, managing soil quality became vital. Fertilizers, containing elements like nitrogen and phosphorus, can be organic or inorganic. Their efficient production has boosted crop yields and supported population growth. However, excessive use can harm natural systems. The video concludes by summarizing the role of fertilizers in enhancing crop production.
