Objective: In Finland fertilization statistics has been compared with mortality statistics of middle aged people and found several associations. The value of such associations can be scanty, if it is not possible to make respective assessment in other countries. FAOSTAT has collected statistics on fertilization and arable land since 1961.The aim of this study has been to assess the associations of consumption of the main mineral fertilizers N, P and K (nitrogen, phosphorus and potassium) (Eq/ha) in Finland (Fin) and West-Europe (WE) during 1961-2000.
Results: Ratio of WE to Fin fertilization rate was 1.86 by N, 1.51 by P and 1.96 by K. Regressions by WE fertilizer rates explained respective Finnish values as follows: N by 89.7 %, P by 82.2 %, K by 70.8 % and NPK by 86.9 %. Details: N rates were nearly identical. P rates reached their maximum in 1973-74 and general consumption reduction occurred since 1989. In the 1980's K's had plateaus in Fin and WE, but P not.
Conclusion: This compliance suggests on assessment these parameters with parameters of public health in WE.
In Finland fertilization statistics has been compared with mortality statistics of middle aged people and found several associations [1-3]. The aim of this study has been to assess the associations of consumption of the main mineral fertilizers N, P and K in Finland (Fin) and West-Europe (WE) during 1961-2000 (Figures 1 & 2).
Annual fertilization statistics (N,P2O5 and K2O) and arable land are from FAOSTAT [3,4]. Fertilizer parameters were changed to N, P and K equivalents per ha (Eq/ha/a).
Ratio of WE to Finnish fertilization rates was 1.86 by N, 1.51 by P and 1.96 by K. Regressions by WE fertilizer rates explained respective Finnish values as follows: N by 89.7 %, P by 82.2 %, K by 70.8 % and NPK by 86.9 %. Details: N rates were nearly identical. P rates reached their maximum in 1973-74 and general consumption reduction occurred since 1989. In the 1980's K's had plateaus in Fin and WE, but P not. Discussions are included in [1-3,6]. Additionally: shorter annual snow cover can explain higher fertilization rates in W-Europe.
This compliance suggests on assessments of these parameters with parameters of public health in West-Europe too.
