Commercial Crop Yields Reveal Strengths and Weaknesses for Organic Agriculture in the United States The analysis we present here offers a new perspective, based on organic yield data collected from over 10,000 organic farmers representing nearly 800,000 hectares of organic farmland. Averaged across all crops, organic yield averaged 80% of conventional yield. However, several crops had no significant difference in yields between organic and conventional production, and organic yields surpassed conventional yields for some hay crops.

> If the world adopted a plant-based diet we would reduce global agricultural land use from 4 to 1 billion hectares > Farmyard manure in natural farming leads to higher yield than conventional method: Study First, these two items are mutually exclusive. Second, about 95% of manure right now is produced by animals that are fed "non-organic" corn, that is produced with the help of fertilizers. Honestly, "organic" people should just study the basics: the nitrogen cycle.

  > these two items are mutually exclusive How? Why? > about 95% of manure right now is produced by animals that are fed "non-organic" corn That's not the only way how to get manure, right? Three field system, for example. And manure is not the only thing we could use, we have also compost and mulch and nitrogen fixing plants and companion plants and agroforestry etc.

    > How? Why? If the world switches to a vegan diet, there wouldn't be any manure. > That's not the only way how to get manure, right? Nope. Not right. > Three field system, for example. And manure is not the only thing we could use, we have also compost and mulch and nitrogen fixing plants and companion plants etc. If you're talking about bilogical methods, then nitrogen-fixing plants are THE ONLY way you can get nitrogen. Animals don't fix nitrogen, they simply concentrate it in the form of manure. And guess what? Plants suck at nitrogen fixation. So overall yields would be around one tenth of the current ones for many important crops.

      > If the world switches to a vegan diet, there wouldn't be any manure. We could, and probably would still have the animals. There are vegan sanctuaries even in this day and age. But even without manure we'd still be ok. > So overall yields would be around one tenth of the current ones for many important crops. Yields were 2-3 times smaller before the "green revolution," not 10 times less. With better methods, processes, and with automation we could further improve yields. This would undoubtedly require more knowledge than the uniform methods we're currently using. Animal agriculture is so wasteful and inefficient that we could absolutely free 75% of the lands we're currently using for reforesting and rewilding and still have 2x more space than we have now for veggies, fruits, and nuts, while feeding everyone sustainably. We should even accept those lower yields than we currently have; the priority should be the restoration of soils and biodiversity rather than the maximal exploitation of natural resources. Soil depletion/erosion is a serious problem, and both industrial and animal agriculture are the culprits.
