afs-71397	Kaila, Armi; Missilä, Hilve	Accumulation of fertilizer phosphorus in peat soils	1956	11	.pdf	application/pdf	4886	254	65	The total P, inorganic P and organic P content of the plots annually dressed with 0, 20, 40 or 60 kg/ha of P 20 5 applied as superphosphate is reported in Table 1. The data in the same paper indicated that during the ten years of an experiment the total content of organic P in a limed lowmoor peat soil increased due to the P fertilizers, and even more intensively than the corresponding content of inorganic P. Jackman (4, 5) has found a rather marked conversion of applied P into organic forms also in mineral soils.	cache/afs-71397.pdf	txt/afs-71397.txt
