I think we're just talking about different things and my link wasn't very relevant. If you actually visit the farms you can immediately tell the differences.

I think we're just talking about different things and my link wasn't very relevant. If you actually visit the farms you can immediately tell the differences. When you visit a large farm, there is always things like tons of wasted space and water not covering some plants while others getting drowned. None of the plants are taken care of nearly as well as small farms (tomatoes usually aren't pruned for example). Overall, from what I've seen, large farms try to compensate for lack of individual plant maintenance by chemical treatments. Here's a link to some "urban farming" that I think scales basically to other sizes: http://www.farmlandinfo.org/sites/default/files/Philadelphia_Harvest_1.pdf http://www.farmlandinfo.org/sites/default/files/Philadelphia... Specifically, if you look at table 3, yield per crop area only decreases with size (1.2 for the largest farms and ~1.42 for the rest): https://seafile.entervice.com/f/175b18396c774698b6d2/ https://seafile.entervice.com/f/175b18396c774698b6d2/ Then there is recent greenhouse indoor farming survey: http://stateofindoorfarming.agrilyst.com/ http://stateofindoorfarming.agrilyst.com/ Here is comparison of revenue per square foot for large and small farms from that survey: https://seafile.entervice.com/f/c0a224916e6742ef9873/ https://seafile.entervice.com/f/c0a224916e6742ef9873/ It really depends on the crop but in this case everything but cannabis had higher yields in small farms. Finally, if you're not convinced, here's some prose from cgiar regarding farm sizes and yields: https://wle.cgiar.org/thrive/2017/03/20/precision-agriculture-bigger-yields-smaller-farms https://wle.cgiar.org/thrive/2017/03/20/precision-agricultur... select quote from there: "In some ways, precision agriculture takes us back to the future. In some developing countries, very small farms tend to have marginally higher yields than somewhat larger farms. This can in part be explained by the relatively higher labor input on small farms, which can rely largely on unremunerated family labor. Under these circumstances, it is possible to check on every corner of the field on a daily basis, pull out weeds individually, and fertilizer precisely." But here they're talking about very modern high precision farming which isn't actually taking place in many large farms. When it does take places it almost matches small farms.
