Abstract
Process for inhibiting the corrosive characteristics of a nitrogenous fertilizing solution comprising incorporating in said nitrogenous fertilizing solution at the moment of its constitution, about 50 to about 150 ppm of at least one of the linear esters of acid phosphates having the formulae; ##STR1## wherein R1 and R2 which are identical or different from one another, are selected from the group consisting of the n-heptyl, n-octyl, n-nonyl and n-decyl radicals.

Process for inhibiting the corrosive characteristics of a nitrogenous fertilizing solution comprising incorporating in said nitrogenous fertilizing solution at least one of the linear esters of acid phosphates having the formulae:
- ##STR3## wherein R1 and R2 which are identical or different from one another, are selected from the group consisting of the n-heptyl, n-octyl, n-nonyl and n-decyl radicals, or the alkaline salts of said esters in an amount efficient to prevent the formulation of insoluble deposits in said solution.
Nitrogenous fertilizing solution having incorporated therein an amount efficient to prevent the formation in said solution of insoluble deposits of at least one of the linear esters of acid phosphates having the formulae:
- ##STR4## wherein R.sub.1 and R.sub.2 which are identical or different from one another, are selected from the group consisting of the n-heptyl, n-octyl, n-nonyl and n-decyl radicals, or the alkaline salts of said esters.
