Abstract: Systems, methods, and/or processes for agricultural parameter determination are provided. One or more can include or use processing circuitry configured to: manage one or more land parcels for agricultural parameter optimization (such as soil organic carbon optimization); and determine one or more agricultural parameters of at least a portion of one land parcel (such as an alleyway between commodity crops) during a first time period without sampling the portion of the one land parcel. Systems, methods, and/or processes for increasing soil organic carbon are also provided.

Abstract: The invention relates to a device for introducing (1) a carrier gas (2) and liquid compounds (3) or a liquid solution into an evaporation chamber (4), comprising a mixing chamber (10), including at least: —a first inlet (8) for the admission of said compounds or said solution (3), —a second inlet (9) for the admission of the carrier gas (2), —and an outlet (13) connected to an inlet of an injector (14), so that a mixture of carrier gas and droplets of said compounds or of said solution is periodically injected, through a single injector outlet (14), into the evaporation chamber (4).

Abstract: An apparatus for liquid delivery of a chemical vapour deposition CVD installation comprises an inlet head equipped with at least one injector having an inlet for delivery of liquid precursors or precursors in solution. A vector gas injection circuit is rendered active simultaneously with injection of the liquid, the vector gas being directed to the vicinity of the injector after being heated. Each injector is cooled individually by water or coolant flow. The evaporation chamber comprises heating resistances for the change of liquid/vapor state of the precursors, and deviation means arranged so that the distance covered by the droplets and vapours of the precursors is greater than the distance in a straight line between the nozzle of the injector and the outlet tube.
