System and process for quantifying potentially mineralizable nitrogen for agricultural crop production

A process of determining a nitrogen fertilization rate for an agricultural crop, said process comprising the steps of:

• a. fluorometrically quantifying at least one amino acid or amino sugar content from of said crop using a salt solution, wherein said amino acid or amino sugar content excludes unexposed amine groups;
• b. determining a potentially mineralizable soil nitrogen content of said crop based on said amino acid or amino sugar content;
• and
• c. determining said nitrogen fertilization rate for said crop based on said potentially mineralizable soil nitrogen content.

A process of providing a site-specific nitrogen fertilization rate for an agricultural crop to achieve a predetermined yield potential, said process comprising the steps of:

• a. quantifying a potentially mineralizable soil nitrogen content of said agricultural crop based on an amino acid or amino sugar content of said crop;
• wherein said amino acid or amino sugar content excludes unexposed amine groups;
• and
• b. providing said site-specific nitrogen fertilization rate for said crop based on said potentially mineralizable soil nitrogen content to achieve said predetermined yield potential for said crop.
