Question

Why are artificial fertilizers sprayed on crops?​

Answer 1

Answer:

Artificial fertilizers are used because they provide elements needed by plants to grow well, such as nitrogen, phosphorus and potassium and replace the essential nutrients for plant growth to the soil after they have been depleted.

Explanation:

Fertilisers provide elements needed by plants to grow well, such as nitrogen, phosphorus and potassium. They can make crops grow faster and bigger so that yields are increased. The compounds used must be water-soluble so plants can absorb them through their roots.Fertilizers are applied to replace the essential nutrients for plant growth to the soil after they have been depleted. Excess amounts of fertilizers may enter streams creating sources of nonpoint pollution. Fertilizers most commonly enter water sources by surface runoff and leaching from agricultural lands.
