Abstract

Aim: Changes in #human non-CHD (nCHD) mortality has not thoroughly been explained. Regressions by #fertilization parameters, e.g. Mg/Ca and K/Mg, have been given and discussed. Daily allowance of phosphorus (P) is about double to the RDA. The possible role of excess phosphor fertilization on human general and vascular health has not got much attention. This study shows regressions of human CHD and nCHD(death- rates) in 1961-2000 by single and #multiple fertilization parameters, assessing especially the difference caused by replacement of potassium with phosphorus in regressions by two parameters or parameter ratios. Mortality and fertilization (Eq/ha) data are from the same sources as earlier published. In the results parameters x are Nitrogen (N), phosphorus (P) and potassium (K).

Results: Associations of [P/Mg], [P;Mg], [P/NPK] and [P;NPK] were stronger with CHD and nCHD than respective associations before replacement of K with P.[x/Mg], explained stronger nCHD than CHD, [x/NPK] explained them similarly and [x;NPK] explained stronger CHD. [P;Mg] explained stronger CHD, [N;Mg] explained stronger nCHD, [K;Mg] explained them similarly. Regression coefficients were positive with P and K, except single K with nCHD. Regression coefficient was positive with [N/Mg], but in other N regressions negative. Associations for given (N 32) regressions were highly significant (p < 0.001) in all but three cases.

Conclusion: Many changes in fertilization are statistically associated with #human mortality. Replacing K by P in CHD and nCHD regressions increased the strength of associations. Causes of associations are discussed.
