Conteúdo: | It is very difficult to determine certainly the precise factor which is responsible for the poor growth of a specific plant under e given acid soil from the fact that numerous soil parameters change as the acidity is altered. In the present paper, predominant factors for poor growth of three kinds of crop plants on acid soils different in acidity was determined by the method that to control plot a complete rate of mineral elements was omitted. The results obtained were as follows: 1. Good growth of radish plants in comparison to the other two plants was considered to be due to a lower sensitivity to aluminum toxicity and higher ability to accumulate mineral elements from kuroboku and its subsurface soils. 2. The poorer growth to tomato plants than egg plants was mainly based upon higher sensitivity to aluminum toxicity. 3. The predominant factors for poor growth were potassium, magnesium and calcium deficiencies in radish plants, potassium, phosphorus and nitrogen deficiencies in egg plants and aluminum toxicity, calcium and molybdenum deficiencies in tomato plants in kuroboku soil. 4. The predominant factors for poor growth of these plants were respectively nitrogen and phosphorus deficiencies in kuroboku subsurface soil.
