**3.1 Drawbacks of fertilisers use alone**

Inorganic fertiliser usage typically necessitates more frequent fertilising. Plants can easily take the nutrients, but they do not stay in the soil for as long. This issue can be addressed by using a slow-release fertiliser, but typically, inorganic fertiliser needs to be applied to the soil often. Although inorganic fertilisers are frequently less expensive, the cost savings may be offset by the need for several applications because it depends on the amount of nutrients in soil. Plants can be burned or scorched if too much fertiliser is used because the nutrients are concentrated and easily accessible. High salinity is also more likely when using inorganic fertilisers. Saline soils contain an excessive amount of salt and can impair a plant's ability to absorb nutrients and water. The soil's surface may develop a crust as a result of these fertilisers.
