How much water does it take to grow enough wheat to make a loaf of bread?

Answer 1

none whatsoever if you have irrigation or your own watering system.

According to Montana State University, both spring and fall wheat crops need between 18 and 21 inches of water per season. this will be determined further by your local climate.

Answer 2

Loaves vary in size, of course, and some use more wheat than others, but there is about 1/5 cup of water in the wheat used to make the 3 cups of flour in a loaf of bread.

You don't "use up" water in growing wheat. Wheat is normally grown without irrigation. Some of the rainfall ends up in the river, where it is used for drinking water downstream, some of it soaks through the ground and eventually makes it to the water table, and some of it ends up evaporating, to fall as rain elsewhere. The wheat kernels have about 14% moisture. Some of this moisture is removed in the flour milling process, some of it evaporates in the baking process, and some is in the finished bread.

In NW Ohio, crops aren't irrigated. Yields average about 5000 pounds per acre, and annual rainfall runs 34 inches. That's 952,000 gallons of water producing 5000 pounds, or 190 gallons per pound of flour. Five pounds of flour is 12 cups, which makes 4 loaves. That means that there needs to be 247 gallons of rainfall per loaf of bread.

Hydroponic wheat experts say the it takes only 3% as much water as growing wheat in soil. That means about 8 gallons of water to grow enough wheat for a loaf of bread. The rest of the rainfall goes to waste.

Answer 3

Wheat requires the sun temperature around 70 to 75 degree F. Whereas the minimum temperature needed is 40 degree F and if the temperature exceeds 95 degrees F means,then the whet will not grow.

Answer 4

How many? I believe one sun is enough, last time I checked.

Answer 5

not alot
