(57) Abstract: The invention can be used in agriculture and soil science, mainly to determine the electrical properties of the soils. The method includes placing the measuring electrodes in the soil. Carry out the impregnation replaceable porous membranes thickened with agar, a saturated solution of potassium chloride, which is salt bridge electrode connecting the electrode to the ground. These membranes are placed between the soil and the salt bridge electrode. This technology will improve the accuracy of the obtained results, performance and simplify the measurement process. The invention relates to agriculture and soil science, namely to methods of determining the electrical properties of the soil. There is a method of determining electrical potentials in soils [1], consisting in the use of electrodes made of dry battery cells, Leclanche. Such electrode is a graphite rod in a mixture of carbon powder, pyrolusite and manganese oxide, impregnated with a thickened solution of ammonium chloride containing chlorides of zinc and copper. The contact of the electrode with the soil is black is Lucena the possibility of dilution of the soil solution electrolyte. The main disadvantage of this method of measurement of electrical fields in soils using such electrodes is different mobility of cations and anions located in the thickened solution electrode. At the electrode-soil occur uncontrolled diffusion jumps of the potential. When measuring the electrical potential between different soil layers lead to significant errors. Closest to the claimed method is the measurement of electrical fields in soils [2], consisting in the use of electrodes connected to the ground through salt agar bridges with a saturated solution of potassium chloride or ammonium nitrate. When placed between the electrodes and the soil salt bridges with solutions of potassium chloride or ammonium nitrate substances, the mobility of the ions which are close, the diffusion potential at the electrode-soil is minimized. In this case, the jumps of the potentials at the electrode - electrode solution and electrode solution the salt bridge solution, both electrodes are almost equal and compensate each other. The decrease in the diffusion potentials leads to the fact that the measured potential difference is close to the potential difference between points of fire is the pollution of such electrodes soil, that distorts the results of further measurements in other soil horizons. Purification of the electrodes is quite complex, requires considerable investment of time and ineffective. The aim of the invention is to improve the accuracy of the obtained results, increase productivity and simplify the measurement process. An object of the invention is the elimination of the possibility of contamination of ground electrodes during the measurements. The problem is solved by placing the measuring polarizadas electrodes with nozzles of the gelled agar saturated aqueous solution of potassium chloride in different soil layers and measuring the potential difference between them. When this contact salt bridges electrodes with soil passes through a replaceable porous membrane impregnated with gelled agar saturated aqueous solution of potassium chloride. The technical essence of the invention consists in the impregnation replaceable, porous membranes the same gelled agar saturated solution of potassium chloride, which is salt bridge electrode connecting the electrode to the soil, and placement of these membranes between soil and salt bridge electrode. Priuchenie contact between them, do not introduce any additional errors in the measurement that significantly simplifies the process of repeated measurements and reduces the error. The following example reveals the essence of the invention. Example. As objects, between which were used to define resulting from contact of the electrical potentials were taken from greenhouse substrate, leached Cuban soil, and peat and sod-podzolic soils of the floodplain R. Yakhroma and its environs. These soils pairs were put into contact with each other, and with the help of the measuring electrodes through the agar salt bridges measured the potential difference between these soils. In one case between salt bridges and electrodes were placed replaceable membrane, and the other doesn't. Replaceable membrane was prepared, soaking pieces of filter paper measuring 1.5 by 1.5 cm saturated solution of potassium chloride containing 2% agar at a temperature of 90. After cooling, the membrane was placed in tube, where they were kept. The measurements were carried out one after the other, three times, fixing the values of the potentials at the measurement and the time taken to carry out all measurements. A total of 18 measurements on zajavljaete for 10 minutes, and closest analogue to conduct these measurements took 30 minutes. Determination error was in the first case, 5-7%, and the second 12-15%. Thus, the invention allows for the holding of a group of measurements to significantly improve the accuracy and to reduce costs and save time. Literature. 1. Pozdnyakov A.
