Description
Photograph of an advertisement for Aerocultor, a machine used to cultivate soil with air, [s.d.]. The advertisement appears as text outlined by a five-line border. The advertisement reads as follows: "Aerocultor (Cultivates the soil by air) Aearoculture is a patented mechanical process of injecting pure air into the soil. It is done under pressure and to depths up to four feet by especially designed equipment. The oxygen and nitrogen of the air is thus delivered to the roots of growing vegetation. Aeroculture fills the soil in all directions with the life-giving elements so prevalent in the air, and displaces dormant and poisonous gases which have been locked in and under the cultivated soils. Aeroculture granulates compact soils, thus enabling water to penetrate to effective depths. Aeroculture accomplishes the results sought by cultivation and plowing, but at reduced cost. Aeroculture removes sour soil conditions subsoils without cutting and destroying roots accomplishes air-slacking of hard pan, plow sole and otherwise impervious soils, where found, in place. Aeroculture stimulates bacterial action necessary for the conversion of natural or artificial fertilizing materials into plant food. Aeroculture contributes directly to the growing of better, larger, sweeter, and finer vegetables, grains, flowers, shrubs, lawns -- in fact, all plant life. These facts -- and they are facts -- you should know. Thousands of dollars and many years have been spent to develop this process -- now call Aeroculture. It is now perfected and in use exceeds all claims made for it. Investigate what has been done by the 'Aerocultor' A. L. Harlow, Sales Manager Phone 115-22 Factory: 316 Azusa St., Los Angeles, Calif.
