METHOD FOR RECOMMENDING PHOSPHORIC FERTILIZER (PF) DOSES FOR LARGE-SCALE AGRONOMIC CROPS IN THE PRESENCE OF CROP RESIDUES ON THE SOIL (CRS)

Abstract

Method for calibrating phosphoric fertilizer inputs to agronomic crops comprising a Mitscherlichian response curve describing the diazotrophic activity of the azotobacterial flora in arable soil in the vicinity of recently buried crop residues, and a phosphoric fertilization method comprising the application of a dose dp of phosphorus thus calibrated directly to said crop residues, advantageously in combination with an azotobacterial inoculum.
