The present invention refers to a novel device for easily extracting the saturated paste solution from the soil, which is useful for manufacturing chemicals resulting from the concentration of ions and nutriments used to characterize the fertility and salinity of the soil. The invention is easily operated as this is a single light piece that does not require electric power to be operated. The device is dismountable and has three pieces: a conical-shaped container through which the soil solution is passed and drained; the central portion of the same contains a cross for discharging the water stored in the tube; a ½ inch tube for controlling the discharge of the solution to be analyzed. The maintenance of the device is easy as it only requires to be washed, dried and stored in a dry place. The average number of samples before requiring maintenance, change of pieces or packings, is of 1500. |
