    We can not assume complete control of environmental factors by means of landscaping, because landscaped fields exist generally in non-closed space. Therefore the significance of landscaped environment, that has the varied characteristics of nature together with the stable characteristics of art, is considered to be as follows; if people, who are adapted themselves to an artificial environment, step in another natural environment, they will feel themselves psychological change under the fresh stimulus, and they will regain vital function by reproductive metabolism when environmental change is rather desirable to them.

    Experiments were carried out to know the effects of three nutrient elements on the growth of American and European lawn grasses (Kentucky bluegrass, colonial bentgrasses-Highland bent and Astoria bent, redtop, Bermudagrass, chewings fescue and Italian ryegrass) in Japan.
    The results obtained were as bollow:
    (1) By want of nitrogen element, as a rule, the growth of the grasses was worst, by want of phosphorus element, it was somewhat better than the former, and by want of potassium element, it was comparatively good.
    (2) In the case of some grasses, the effects of three nutrient elements in summer differ from in autumn. Iu Kentucky bluegrass, the effects in autumn were more remarkable than in summer, while in Bermudagrass, the effects were comparatively remarkable in summer, In bentgrasses, the effects were remarkable in both seasons, but in chewings fescue and Italian ryegrass, the effects were not remarkable.
