Compliance between Finnish and West-European Fertilization Rates in 1961-2000
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2018, Vol 8, Issue 5
Abstract
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. Introduction 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). Materials and Methods 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).
