| The root uptake of 134 Cs by forage plants was studied as a function of growth stage and N fertilization with biotite supplementation.The study was conducted by means of pot experiments with peat soil. In the growth stage studies,ryegrass,white clover and yellow-flowered lucerne were cut once 30,60 or 90 days after sowing or three times at intervals of 30 days.In the one-cut system, at 90 d,the activity concentration of 134 Cs in ryegrass and clover was higher and that in lucerne lower than in the three-cut system.In both treatments,the activity concentration in ryegrass decreased and that in legumes,generally,tended to increase with time.In the N fertilization studies,ryegrass was grown at different levels of ammonium nitrate (100,200 and 400 mg N l -1... |

| In a three-year Research program of organic food and farming in Finland there are five projects under the theme of animal husbandry and food safety. The projects focus on red clover as feed for cattle, on suckler cow production and pathogen prevalence on organic cattle and pig farms. First results are now available. |
