Are there alternatives to synthetic fertilizer?

By Austin Tannenbaum
YES

Many alternatives to synthetic fertilizer exist. The USDA lists "compost, cover crops, plant by-products, animal manure, and other biological materials" as common choices used in organic farming to avoid synthetic fertilizer.

Synthetic fertilizer increases short-term crop yields by adding limiting nutrients such as nitrogen to the soil. However, it also contributes to global warming via nitrous oxide emissions and disrupts ecosystems via runoff.

In addition to cover crops that protect the soil and organic fertilizers such as compost and manure, farmers also employ crop rotation to enrich soil, utilizing nitrogen-fixing crops such as legumes. 

There is disagreement about whether organic farming can feed the world. A widely cited Nature study from 2017 says it is possible, but assumes more land is made available for agriculture, more people adopt a plant-based diet and less food is wasted.

This fact brief is responsive to conversations such as this one.
ABOUT THE CONTRIBUTOR
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
