Fuel ethanol is significant but not the largest use of corn. Livestock feed is the largest use of corn, which connects into the larger conversation about food and sustainability. About 45-50% of all US corn crop and 70% of soybeans is used for animal feed. Almost all of my crop goes to those uses eventually.
As someone with a medium to large scale farm, the fertilizer price rises have been pretty severe. Already up about 40% over last year. It's really a confluence of factors. Natural gas is required to produce ammonia (it's about 80% of the cost), and usually the the prices of both move together, but this has outpaced those global fuel increases. Supply chain disruptions, increased demand, new tariffs on urea, higher fuel costs have all contributed.
Fertilizer accounts for about 35% of the input costs for my farm (corn and beans) and 25% for other crops so price changes have a pretty significant impact. There's pros and cons, price increases means less fertilizer applied and lower yields, but also less environmental impact and runoff/leaching.
Yes there should be no difference. I believe this is due to how Roku handles account region settings. When you create an account and register your Roku it gets region set to your country at that time. According to what I've read this becomes a permanent account setting, which you can change this by contacting Roku support, but they only allow you to change it once.
A possible workaround is to create a new separate Roku account from your new country and add it to your Roku, however beware this requires factory resetting your device. Also before doing so make sure Amazon Prime is available in your new country.
