Conclusion

Fertilizer is necessary for providing nitrogen to crops. Nitrogen is an essential element for plant growth and development. Without nitrogen, plants would be unable to photosynthesize, produce chlorophyll, or create new cells.

Nitrogen is found in the atmosphere, but it is unavailable to plants in this form. Nitrogen must be “fixed” by bacteria in the soil before plants can use it. This process of nitrogen fixation is essential for the growth of all plants.

Fertilizers provide nitrogen to crops by supplying it in a form that plants can use. Inorganic fertilizers, such as ammonia, are manufactured using the Haber-Bosch process. This process combines nitrogen from the atmosphere with hydrogen to create ammonia.

The ammonia can then be used to create other inorganic fertilizers, such as urea and ammonium nitrate. These fertilizers are then applied to crops to provide them with the nitrogen they need to grow.
