Soil chemical sensor and precision method for determining the amount of agricultural chemicals.

A SYSTEM OF CHEMICAL DETECTOR OF THE LAND AND PRECISION AGROCHEMICAL DELIVERY IN REAL TIME INCLUDES A PLURALITY OF TOOLS FOR COUPLING TO THE LAND, TOGETHER WITH INDIVIDUAL DETECTORS OF THE LAND THAT MEASURE THE CHEMICAL LEVELS OF THE LAND. THE SYSTEM INCLUDES THE ADDITION OF A SOLVENT THAT QUICKLY SATURES THE SOIL / TOOL INTERFACE TO FORM A DRIVING SOLUTION FOR DESALTED CHEMICALS FROM THE GROUND. A MULTIPURPOSE ELECTRODE, POSITIONED WITHIN A MULTIPURPOSE FRAME OF THE COUPLING TOOL TO THE GROUND, APPLIES A VOLTAGE OR PRINTS A CURRENT BETWEEN THE ELECTRODE AND THE TOOL FRAME. A REAL TIME CHEMICAL DETECTOR OF THE LAND AND CONTROLLER DETECTS THE ELECTROCHEMICAL REACTION RESULTING FROM THE APPLICATION OF THE VOLTAGE OR CURRENT TO THE DESALINATION, MEASURES IT BY METHODS OF RESISTIVITY AND COMPARED TO THE PREVIOUSLY ADJUSTED LEVELS OF RESISTIVITY FOR SUSTANTS. STILL HIGHER ACCURACY IS OBTAINED THROUGH THE CALIBRATION OF THE SECOND CURRENT APPLIED THROUGH THE LAND WITHOUT SOLVENTS. THE APPROPRIATE CONCENTRATION IS SEEN LATER, AND THE SERVO-OPERATED DELIVERY SYSTEM APPLIES THE APPROPRIATE AMOUNT OF FERTILIZER OR AGRICULTURAL CHEMICALS, SUBSTANTIALLY IN POSITION FROM WHICH MEASUREMENT OF THE FIELD WAS TAKEN.
