And
precision agriculture, a subdomain of agricultural engineering, which involves the use of satellites and artificial neural networks among others, is often
employed to spot crop stress and make adjustments to irrigation and fertilization regimens.
Methods such as accurate water measurement and soil moisture monitoring, laser - leveling fields, using conservation tillage to retain soil moisture, switching to low energy
precision application sprinklers, lining canals, and
employing subsurface drip irrigation where possible could save upwards of 40 percent of
agriculture's water use while improving crop yields and saving energy.
