Accumulation of fertilizer phosphorus in peat soils

In the present paper the results of a preliminary study of the accumulation of fertilizer P in peat soils is reported. The material consisted of samples from an old field experiment in Leteensuo Experiment Station and from 12 experiments on newly reclaimed soils in Northern Finland. The primary obje...
