Advantages
Arguably the biggest advantage of chemical fertilizers is that they tend to cost much less than organic fertilizers. The higher cost of organic fertilizers is due not only to the need to harvest organic material to use in the fertilizers but also to the higher costs of being certified organic by government regulatory agencies. The promise of equivalent nutritional content and lower purchasing costs greatly popularized synthetic fertilizers and, according to one scholarly source, "has greatly increased crop yields and made the green industry more cost efficient."
DisadvantagesRecent concerns over the environmental effects of using synthetic fertilizers have led many to reconsider synthetic fertilizers as a suitable alternative to organic fertilizers. On the production side, synthetic fertilizers require more fossil fuels to produce and create more greenhouse gases during production than do organic fertilizers. Some of the synthetic compounds used to manufacture chemical fertilizers can have negative environmental effects when allowed to run off into water sources. There is also some evidence that plants treated with chemical fertilizers do not yield as productive results as those treated with organic fertilizers.Similar questions
