The proposed design of the probe allows the authors to take samples of the soil undisturbed. Existing devices for sampling of soil can be divided into devices for selection with the disturbed or undisturbed. Оn the proposed design the forming concluded sampler sample occurs due to extraction of the device from the soil hole, and the determination of physico-chemical properties can be carried out simultaneously with taking soil samples. On the collapsible body composed of two halves, set the container, based on the front end internal shoulder collapsible body. At the rear end of the container lid secured with pins outwardly through the slots missing wall of the body, and the latter is put on the flange adjacent the rear surface of the pins. On the body set pusher, between which and cover the spring is installed. On the annular groove collapsible enclosure facing the front end of the container stacked two cutting strings, one for each half of the collapsible body. With the introduction of the probe into the soil pusher latter fills the container, and when pulling the strings cut cutting pusher soil sample at the bottom of the container and ensure removal of the probe. Along with taking soil samples is determined its physicochemical properties, for example, soil moisture. For this on sampler set electrode electrically insulated from the housing and cover by textolite sleeves, can be connected to the electrical device. The results of laboratory and field tests have proved that the developed sampler operable, allows to obtain soil samples with undisturbed structure with a volume of 125 cm 3, can be used to determine dimensional weight, also the direct determination of physical and chemical properties of soil, such as moisture on electrical performance, using as supply voltage signal current frequency of 100-200 kHz.samplessoil samplerundisturbedstructureпробыпочвыпробоотборникненарушеннаяструктура[Отбор почвенных проб и их анализ в точном земледелии [Электронный ресурс]. - URL: http://www.mcx.ru/news/ news/show/36322.htm (дата обращения: 15.05.2015).][Пат. №2525080 Российская Федерация, МПК E02D1/04, G01N1/04.
