afs-5762	SAARELA, I.; JÄRVI, A.; HAKKOLA, H.	Phosphorus status of diverse soils in Finland as influenced by long-term P fertilisation 2.Changes of soil test values in relation to P balance with references to incorporation depth of residual and freshly applied P	2004	19	.pdf	application/pdf	11187	503	62	The total pool of soil P was also influenced by leaching and erosion. The higher percentages of applied P previously recovered by Barkoff (1959) in the chemical fractionation of soil P may be explained at least in part by the infrequent tillage operations, as typical for the old ley-dom- inated crop rotation.	cache/afs-5762.pdf	txt/afs-5762.txt
