ramble is good.
why do they rotate with cotton and not soybeans?
Dunno. Nobody grows soybeans in California. Those guys in the Midwest all dryland farm for the most part – plant and let God irrigate it up. Harvest when he’s done.
Going forward with the subsurface drip, you have to cultivate something that is compatable with the drip tape and doesn't destroy it. Cotton grows well on 30" row centers. Tomatoes are farmed on 60" beds, so you can make it work. Corn makes too much post harvest debris. Alfalfa is grown flat so that won't work either.
really, though, why should cotton (or other thirsty, low price crops) be grown in CA at all since water is at a premium?
Because they used to be profitable. Be careful – you’re fixing to fall into a trap. People talk about rice, alfalfa, and cotton as evil because they use a lot of water. It’s a little more complicated than that.
Rice requires a lot of water because you have to keep it flooded for 120 days or so. There is a ton of excess water north of the Delta that otherwise would run out through the Oakland bay. Also, the land they farm rice on is prone to flooding almost every other year, making it useless for anything other than……rice. If they stopped farming rice, we wouldn’t save a gallon.
Alfalfa is a low value crop and water intensive - because it contains a lot of water. Do you like milk at current prices? How about cheese and ice cream? Because without alfalfa there is no cattle feed. It may be inefficient, but it’s necessary if you want dairy products, and as inefficient as it is, it’s also the most efficient mechanism to feed dairy cows.
Cotton production has fallen off a cliff in California for the reasons we are discussing.

You still need cotton as a rotational crop for tomatoes as a management tool, primarily for nematodes (a microscopic organism that feeds on certain crops). There are around 2000 types of nematodes. Only 4 or 5 are bad for your particular crop. You can’t just single them out (the rest are beneficial), you either fumigate and kill all of them or you rotate crops and the bad ones die because they don’t have their preferred plant to lunch on. They have this problem with wine grapes from time to time and have to pull their entire rootstock and replant.
shouldn't the farmers have to take into account the price of their supply of water (which they get a huge federal subsidy on, or used to)?
They do – see the cotton acreage graph.
The water problem in California is a matter of storage and logistics. There’s plenty of water North of the Delta. They used to pump the excess out of the delta for the California Water Project, but that has been greatly reduced because of the effects on the fish in the Delta. They used to pump so much out of the delta it would cause the river to run backwards and cause salt water intrusion out of the bay into the delta.
This is a bit of a chicken and egg argument. Nobody was growing out there until the government decided it needed the production and built the project – hence the subsidy, which was an interest free loan paid back over 50 years. The government induced the development, and has an obligation not to yank the carpet out from the growers now ‘somebody’ changed their mind.
why not stick to high value crops like tomatoes, strawberries, fruits, etc?
That change is happening, but you must remember, you have to make a market for what you grow. To grow tomatoes you have to get a contract from a cannery else you won’t have anybody to deliver to. Growing commercial strawberries is a lot like avocados, you need to have a special climate and the right type of high drainage sandy soil (Irvine @ the El Toro Y FTW!).
A decade ago, my family’s operation was a rotation of cotton and alfalfa and silage corn. This year, it’s tomatoes and alfalfa and almonds. Next year it’s tomatoes and almonds – provided everything works out okay.
Also, you don’t just ‘switch’ crops without cost. To do 120 acres of tomatoes required a $125,000 irrigation system and $180,000 in additional working capital. That was about four years worth of free cash flow on an average 1800 acre California farm (assuming average year).
Fruits are horrible business. You have huge issues with accounts receivable realization. You grow a crop, then the real costs get you in labor to harvest and cold storage and transportation. Then, after it’s all sold, your end customer may decide there was something wrong with it and take a discount of 50-80% on what they agreed to pay, and there’s not a damn thing you can do about it because your product is long sold and gone. The fruit business right now is just horrible.
why not let wetter parts of the world supply the cotton?
This is a subsidy problem. Everyone on the planet who grows gets subsidies. Seriously - everybody. If the US were to remove the subsidy, it would destroy the US domestic production because the US grower would be at a price disadvantage to the rest of the world – losing the domestic production does not help the US consumer. In short, free trade my ass. It’s a total joke.
Example – in the fall of 1992, the adjusted world price of cotton fell from $0.65 to $0.30 The US had a subsidy strike price around $0.90, and paid the grower the difference. It cost about $0.88 to grow it. Greece had a strike price of $4.50 – they slapped an import tariff of $4.20 on every pound imported, and transferred it back to the grower!
If you can buy it on the world market for thirty cents, it costs you eighty eight to produce it, and your Greek competitor set a floor for their domestic producers at $4.50 PLUS you can’t sell any cheaper, how you gonna compete with that? Do you want to pay $4.50 instead of $.90 like you did before? Earlier in this thread I take Mish to task for advocating against farm subsidies precisely because he misses the above point.
The rest of the world isn’t going to drop their subsidies, much to the chagrin of the African contingent, who believes that if the world would drop their subsidies the Africans would be able to compete on the worldwide market. The reality is if the world got rid of it’s subsidies the US grower would decimate everyone else because we are so much more efficient if you count $1 of inputs to = pounds output. Most of that is technology.
