Title (EN) SOIL NUTRIENT MONITORING SYSTEM
(FR) SYSTEME DE CONTROLE POUR LES ELEMENTS NUTRITIFS DU SOL
Abstract:
(EN) An improved apparatus for measuring soil nutrient concentration or pH level in soil samples of a known size is used in combination with a soil sampling and transport subassembly (12, 14) mounted on a farm vehicle (10) for on the go measurement of soil nutrient or pH levels in a field. A controller (18) is provided to sequence the operation of the various subassemblies and the system includes provision of a fertilizer applicator (20) automatically having its fertilizer application rate controlled based upon the measured soil nutrient concentrations or pH levels and ground speed of the farm vehicle (10).
(FR) On utilise un dispositif amélioré, permettant de contrôler la concentration en éléments nutritifs et le pH d'échantillons de sol de taille connue, en l'associant à un sous-ensemble de prélèvement d'échantillons et de transport (12, 14) de sol, monté sur un véhicule agricole (10), afin de mesurer sur place la concentration en éléments nutritifs du sol ou le pH d'un champ. Une unité de commande (18) commande le fonctionnement successif des différents sous-ensembles. Le système comprend un applicateur d'engrais (20), dont le taux d'application d'engrais est commandé automatiquement sur la base de la concentration en éléments nutritifs et du pH mesurés, ainsi que de la vitesse d'avancement du véhicule (10).
