Abstract:
The invention relates to a system for evaluating in situ and continuously the crop-growing potential of an agricultural soil comprising a device for estimating hydrogen and nitrogen flows comprising water-monitoring devices, an earth-monitoring device and a hygrometric device, these being equipped with sensors intended to measure an amount of nitrates, temperature and pH, the temperature and moistness of a piece of ground, and the temperature of the air. Said monitoring devices each being connected by cables to dedicated acquisition boards. The estimating device furthermore comprises a microcontroller module controlling said acquisition boards and a communication module, said communication module sending measured results to a server. The estimating device is characterised in that the water-monitoring devices are placed respectively at 30 cm and 50 cm depth and the ground-monitoring device is placed at 50 cm depth, in that the monitoring devices are connected to the microcontroller module, which makes the requests for measurements and communicates the measured raw data to the server by means of the communication module, and in that the microcontroller module (5) activates the hygrometric device, at a regular and adjustable frequency, in order to measure the humidity of the air and to determine the periodicity of the requests for raw measurements of the various water- and earth-monitoring devices. The invention furthermore relates to a method implemented in the above estimating device.
Abstract:
A system and method to obtain correct gas density and flux measurements using (i) gas analyzer (open-path, or closed-path gas analyzers with short intake tube, or any combination of the two); (ii) fast temperature or sensible heat flux measurement device (such as, fine-wire thermocouple, sonic anemometer, or any other device providing fast accurate gas temperature measurements); (iii) fast air water content or latent heat flux measurement device (such as, hygrometer, NDIR analyzer, any other device providing fast accurate gas water content measurements); (iv) vertical wind or sampling device (such as sonic anemometer, scintillometer, or fast solenoid valve, etc.) and (v) algorithms in accordance with the present invention to compute the corrected gas flux, compensated for T-P effects. In case when water factor in T-P effects is negligible, the fast air water content or latent heat flux measurement device (item iii in last paragraph) can be excluded.
Abstract:
An analysis method includes the steps of causing a moist sample to react with a reagent and measuring concentration of a particular component contained in the sample based on the state after the reaction of the sample with the reagent. The reaction step and the measurement step are performed while the amount of moisture contained in the air in a space accommodating the sample and the reagent is directly or indirectly measured. The method further includes the step of correcting the measurement result of the concentration of the particular component based on the amount of moisture contained in the air.
