“…A large part of the phosphorus occurred in organic form, and, almost without exception, this percentage of total phosphorus increased with the depth: in undecomposed plant material this proportion was about
50—60 per
cent, in the surface layers 70 per
cent, on the average, in deposits deeper than
50 cm seldom less than 80 per
cent and it could even reach 95 per
cent. 1he amount of organic phosphorus expressed as a percentage of organic dry matter was low in most of the samples and although it tended to increase with the depth only in 11 of all the 122 samples values higher than 0.1 per
cent were obtained. …”
