| Abstract: | Growth response of crop plants to a soil with a low level of each nutrient element is different among species.The differences are mainly caused by (1) difference in the internal requirement for each nutrient element and (2) difference in the absorbing power of soil with low nutrient level.When the internal requirements are satisfied by the absorbing power, the crop plant suffer from deficiency of the nutrient element and deficiency symptoms appear.Importance of plant function to secrete organic compounds from root in the absorption of P, Fe,Mn, Zn and Cu were emphasized.Typical deficiency symptoms of each element in crop plants and the causes of nutrient deficiencies are discussed with some current thinking of diagnostic techniques for efficient fertilizer management.In the case of nitrogen which is a key element in obtaining high or reasonably yields, growth response to the nitrogen levels of soils is more complicated.Therefore it is discussed separately. |
