The Multiplication Of Formulas
Categories:
MIXTURES FOR CROPS
Fertilizer manufacturers have made all
possible combinations of fertilizer materials, using them in various
quantities. Each manufacturer has given a mixture a brand of his own,
and confusion reigns. There is no formula for a soil or crop that will
remain absolutely the best, even for one particular field. It
represents one's judgment of the present need, and is employed subject
to change, just as is the prescription of a physician. It is usually
only an approach toward the most profitable amount and kind of
plant-food that may be supplied. The one important consideration is
that no manufacturer can know the need nearly so well as the
intelligent farmer who knows the history of his field and constantly
tests its ability.
