摘要：

A trial carried out in a greenhouse over a two-year period is discussed. The effects on Cs-137 concentration in plants, roots and soil have been investigated versus the grassland species composition (legume, grass and mixture) and eight combinations of mineral fertilizers (NPK). The results indicate: (a) the effect of K fertilizer in reducing Cs-137 plant absorption; (b) the effect of N fertilizer in favouring grass growth and radiocaesium absorption; (c) for all fertilizer combinations, a higher Cs-137 storage in the root system of the legumes and a lower Cs-137 absorption in the plants.
