With the help of a loan you are able to pay someone to dig a well that can be used to water some of your fields. You dig ditches at the high ends of all your fields and then bury lathe boxes that run from the ditches into every row of wheat. The lathe boxes allow the water to be turned on and off when the row no longer needs more water. Each acre of wheat takes 900,000 gallons of water in a year so for your 160 acre farm you will need 144 million gallons of water to substitute the water that is not coming through rain.
