Underground piping is used to pump water from a water source (like a lagoon, reservoir or river), and send it through large sprinklers that are positioned (and built) above th…e crops. Water is then sprayed through these large sprinklers, descending on the crops much like rain does. (MORE)
moat irrigation are used to carry buckets of water where they are needed. Much like clotheslines that use pulleys to move clothes nearer or further away, pulley systems for ir…rigation are designed to cut down on the amount of manual labour needed to take care of gardens or farmland. Since pulleys automate part of the process, they are a cheap and useful way to carry water to plants and soil. Pulleys must be installed aboveground - they may be tied to stakes that are buried in the earth - strong rope will hold the pulley-based irrigation system together. (MORE)

Irrigating with water of higher salinity than a crop can tolerateresults in yield loss and decreased quality. Plants vary greatly in their tolerance to saline water. The exten…tof yield loss when plants are irrigated with saline water dependson a number of factors including soil type, drainage and thefrequency, method and time of irrigation. (MORE)
Archaeological investigation has identified as evidence ofirrigation where the natural rainfall was insufficient to supportcrops for rainfed agriculture. Perennial irrigation …was practiced in the Mesopotamian plainwhereby crops were regularly watered throughout the growing seasonby coaxing water through a matrix of small channels formed in thefield (MORE)
