Eli5: how do farmers water their fields? If it doesn’t rain are they just screwed over for the year?

Modern farms use mobile [irrigation systems](https://ruralwaterdirect.com/media/magefan_blog/RuralWaterDirect-120531-Farm-Irrigation-System-Blogbanner1.jpg) to ensure that their crops get enough water. They factor in how much water the crops have gotten from rain and use artificial systems to augment that to get the crops what they need.
Modern farming is actually incredibly scientific and complex. Soil additives, pesticides/herbicides, water levels, even the seeds themselves are all carefully selected and monitored to maximize crop yields in a given area.
