Saarela, Into (2008) Changes of yield responses and soil test values in Finnish soils in relation to cumulative phosphorus and potassium balances. In: NJF Report, Nordic Association of Agricultural Scientists, 4 (2), pp. 52-55.
Field experiments with five rates of annual P fertilisation were carried out at 24 sites in Finland 1977-1994. A summary of the yield results was calculated on the basis of the amounts of P recommended to cereals according to STP in early 1990s.
The effects of repeated K fertilisation were studied at 21 sites in 1977-1994.
