Summary The effect of different phosphorus supplies on the uptake, translocation and accumulation of14C-urea by orchard grass was investigated. Phosphorus starvation inhibits the uptake, translocation and accumulation of the carbon of urea similarly to the nitrogen of urea. As compared with the uptake process the reduction of the accumulation is much more effected by the inhibition of the carbon translocation from roots to the aboveground parts. Lack of phosphorus also decreases the incorporation of the14C of urea into high-molecular compounds. The effect of phosphorus deficit on the accumulation of14C-urea increases with time of starvation.
