一般认为土壤图在生产中和农业行政上往往难以实际应用。这一情况是由种种原因造成的。为了解决这一问题,足立认为必须绘制大比例尺土壤图和应用土壤图。目前除已有高密度的调查外,在肥力保持基本调查中,正继续努力绘制生产性分级图以及土壤肥力保持措施图。纵然如此,仍感到土壤图难以被应用。其原因除土壤图难于理解外,也因为尚未建立根据土壤调查的测定值来判断土壤生产力的方法。
It is generally considered that soil maps are often difficult to apply in production and in agricultural administration. This situation is caused by various reasons. In order to solve this problem, Adachi considers it necessary to draw large-scale soil maps and soil map applications. In addition to the high-density surveys currently under way, efforts are continuing to draw up production grading charts and soil fertility maintenance plans in the basic survey of fertility maintenance. In spite of this, we still find it difficult to apply the soil map. The reason for this is that it is difficult to understand in addition to the soil map and because no method has been established for determining soil productivity based on the measured values of the soil survey.
