"The use of sprinkler systems, made from aluminum, in the irrigation of soils for farming is reviewed. Rain conditions are often adverse leaving dry periods when the plant survives but does not reach the best size and quality. Both too dry and too wet soil leads to plant decline or death. Early irrigation methods including flooding or furrows had disadvantages ranging from erosion to excess water, leaching valuable plant foods. Sprinkler irrigation applies the water under complete control, uniformly, and only as fast as the soil can absorb it. The introduction of light and portable metal systems has expanded the use of this type of irrigation. The sprinkler system is explained as a farmer irrigating his field is shown setting it up and moving it around. A pump is set up at the nearest water source - lake, river, swamp or stream - and the water is piped to the field. The system is adaptable to different topography and various soil types. This sprinkler irrigation system insures against drought and provides a rich harvest of any crop in any climate. The film emphasizes that 'It is very important, in the face of growing world need for food, that all arable land, including marginal land, be brought into maximum production.'"
