afs-71549	Kaila, Armi	Effect of incubation and liming on the phosphorus fractions in soil	1961	9	.pdf	application/pdf	3758	162	57	The differences in the various fractions of inorganic phosphorus in the samples treated with superphosphate and in the untreated samples are the following: I' ppm Loam soil Silt soil extracted Original Incubated Incubated Original Incubated Incubated by with lime with lime NH 4 CI 2 3 5 13 5 NH.F 58 58 60 39 40 38 NaOH 43 The corresponding differences in the values for the samples from the plots treated with hyperphosphate and from the untreated plots are the following: P ppm Loam soil Silt soil extracted Original Incubated Incubated Original Incubated Incubated by with lime with lime NH 4 CI 1110 2 1 NH.F 21 37 21 17 21 16 NaOH 23 27 12 25 30 16 H2 SO, 222 204 231 197 171 193 As could be expected, in both soils the hyperphosphate phosphorus is accumu- lated mainly in the acid-soluble fraction.	cache/afs-71549.pdf	txt/afs-71549.txt
