Wireless soil moisture monitor is superior to alcohol combustion method to measure soil moisture Soil moisture is an important part of the soil and an important soil fertility factor. The determination of soil moisture couplets has two purposes: first, to understand the soil moisture status in the field, and to provide basis for soil cultivation, sowing, and reasonable drainage and irrigation; and secondly, to determine the moisture content of dried soil in indoor analysis work, and to dry the soil. Weight converted to dry soil weight. Can be used as the basis for the calculation of various analysis results. Alcohol combustion method: Method principle: This method uses the heat released from the combustion of alcohol in the soil sample to evaporate and dry the soil moisture. The percentage of soil moisture is calculated by the difference in mass before and after combustion. The temperature of the soil rises rapidly to 180-200°C just a few seconds before the flame is extinguished. Then the temperature quickly drops to 85~90°C and cools slowly. Due to the short period of high temperature, there is little loss of organic matter and salts in the sample. Therefore, this method has certain reference value for the determination of soil moisture content. Procedure: Weigh about 5 g of soil sample (accuracy 0.01g) into an aluminum box of known quality. Then add alcohol to the aluminum box until it is completely submerged, and tap the aluminum box several times on the table to evenly distribute the soil samples in the aluminum box. Put the aluminum box on the asbestos wire or wooden board, light the alcohol, and use the knife or glass rod to gently turn the soil sample to help burn. After the flame is extinguished, the sample is allowed to cool, and then 2 ml of alcohol is added dropwise to perform the second combustion, and then cooled and weighed. Under normal circumstances, the soil sample can be constant weight after 3-4 burnings. The results were calculated for the determination of moisture absorption of the same dry soil sample. Wireless soil moisture monitor method: The wireless soil moisture monitor is one of the instruments for measuring soil moisture. The instrument is applicable to the latest public opinion monitoring specification SL000-2005. It can be flexibly configured according to user requirements. A single system can perform up to 60 monitoring points. Points were measured at the same time. In addition, the portable soil moisture temperature measurement instrument can also measure soil moisture, and it also has a function that can measure the soil temperature, because the change of soil moisture is closely related to the soil temperature, so if we can measure the soil moisture, we can also measure Soil temperature, then the mastery of soil moisture can be more thorough. Multi-parameter soil measuring instrument will also participate in the determination of soil moisture. Multi-parameter soil measuring instrument is a name that can measure multiple parameters, such as soil temperature, soil moisture, atmospheric temperature, atmospheric humidity and dew point 5 parameters, is a Multifunctional instruments. The wireless soil moisture monitor also has an advantage over other similar products in that it enables wireless transmission of data because the wireless soil moisture monitor contains a GSM/GPRS/radio module and thus enables wireless transmission. This is also true for other methods such as alcohol burning and drying methods.
