Composition Of Plant Not A Guide








It has been pointed out that a
chemical analysis of a soil is not a dependable guide in the selection
of a fertilizer. Years ago the theory was advanced that the analysis of
the crops desired should be a guide, but it has proved nearly
worthless. This theory does not take into account the soil's supply of
plant-food. Moreover, a certain crop may demand a large supply of an
element at a time of the year when the soil's supply is inactive. The
need of nitrogen for grass in the early spring, before nitrification in
the soil is active, is an illustration. Let the causes be what they
may, the fertilizer formulas that call for plant-food in a fertilizer
in the same proportions that it is found in plants are disappointing in
their results. The analysis of the plant is not a dependable index.
