They are then able to take in atmospheric nitrogen, usually unavailable to plants and convert it to a form which plants can use. This is good for the bacteria, the bean, squash and, especially, corn!
As a plant that uses C 4 carbon fixation, maize is a considerably more water-efficient crop than plants that use C 3 carbon fixation such as alfalfa and soybeans. Maize is most sensitive to drought at the time of silk emergence, when the flowers are ready for pollination.

[13] [14] The total water extraction from center-pivot irrigation in the area is estimated to be about 5.42 million acre-feet of water per year. [15] In 1950, irrigated cropland covered 100,000 hectares (250,000 acres). With the use of center-pivot irrigation, nearly 1.2 million hectares (3 million acres) of land were irrigated in Kansas alone.
Until the 1960s, there were fewer than half the number of people on the planet as of 2024. People were not as wealthy as today, consumed fewer calories and ate less meat, so less water was needed to produce their food. They required a third of the volume of water humans presently take from rivers.
