Plant elemental composition and element ratio in some crops at the flowering stage

Abstract

The elemental composition of winter wheat, spring barley, oat, rye, buckwheat and potato at flowering stage as well as the molar ratio of elements to each other in these crops were determined. Presented is a new theoretical approach to fertilization based on the view that knowing the ratio of elements in crops at the flowering stage can be useful in determining the appropriate ratios of fertilizer components in plant nutrition and fertilization.
