One of the key factors that contribute to the high demand for fertilizers is the rapid population growth, along with an increased requirement for food production. Based on worldwide agricultural statistics, fertilizers have played a significant role in ensuring food security for a large portion of the world's population. As highlighted by ‘Our World in Data’, nearly half of the world’s population depends on food produced through the use of fertilizers.
The rise in food consumption implies that farmers would be required to boost their crop production on less agricultural land. This necessitates the need for using fertilizers, not only to ensure that the soil nutrients remain balanced but also to enhance the growth rate of the plants. According to the Food and Agriculture Organization of the United Nations (FAO), the use of fertilizers has resulted in more than a 50 percent increase in crop yields worldwide, especially in cereals and oilseeds.

Expansion of Intensive Farming Practices
A further contributor towards the rising need for fertilizers includes the increasing prevalence of intensive agriculture. Contemporary agriculture depends on adding nutrients to keep up with the required level of efficiency. The natural condition of many soils does not have enough quantities of essential nutrients such as nitrogen, phosphorous, and potassium.
The global statistics related to agriculture reveals that fertilizer use has risen almost 59 percent since 1980 up until 2022, which aligns closely with the increase in agricultural output for the same period.
This demonstrates the necessity of fertilizers within contemporary agricultural systems, allowing farmers to harvest crops consistently at higher intensities of cultivation.

Increasing Nutrient Depletion in Agricultural Soil
The repeated cultivation of crops leads to the loss of necessary nutrients in the soil, causing deficiency in essential nutrients. In order to compensate for such a problem and continue with soil productivity, the application of fertilizers is necessary.
According to data by FAO on the use of agricultural fertilizers across the globe, inorganic fertilizer use in agriculture amounted to about 185 million tons of nutrients per year in 2022. The percentage of nitrogen in the application of fertilizers was 58 percent of total fertilizer use.
Replenishment through fertilizers is necessary in order to prevent such problems in the future.
