An apparatus, method and system for applying a biologically active or chemical substance to a relatively large volume of harvested or pre-harvested crop includes relatively small container (20) of a mixture biologically active or chemical substance and water in fluid communication with fluid conduit (14). A pump (40) moves mixture from the bottle through the conduit. A source (40) of pressurized air is in fluid communication with the conduit to aerate the mixture. The aerated mixture is expelled through a nozzle (12) at distal end of the conduit. In one aspect, the controller (80) can monitor speed of the pump by monitoring operating voltage of the pump. Speed of the pump can be adjusted to adjust application rate. In one aspect, a process combines a flow of air through an orifice with the metering of a low volume of additive, such as an aid to preservation, to a crop as it is being cut or harvested to provide for even distribution of the additive to the crop.

L'invention porte sur un appareil, un procédé et un système d'application de substances à activité biologique ou chimiques à des quantités relativement importantes de récoltes prérécoltées ou récoltées, utilisant un récipient relativement petit (par exemple un bidon) de ces substances, et de l'eau traversant un conduit. A cet effet, on utilise une pompe transférant la substance du récipient dans le conduit et de l'air comprimé traversant le conduit pour aérer la substance qui est éjectée par une buse située à l'extrémité distale du conduit. Dans une exécution, un régulateur module la vitesse de la pompe, en agissant sur sa tension d'alimentation, pour adapter son débit aux besoins. Dans une autre exécution, le flux d'air est combiné à un additif dosé de conservation des récoltes coupées ou récoltées, pour en assurer la répartition homogène.
