soilpHIt is a strength indicator of soil acidity and alkalinity, and an important influencing factor on the basic properties and fertility of soil. It directly affects the existence, transformation, and effectiveness of soil nutrients, thereby affecting the growth and development of plants. soilpHCommonly used as an important reference for soil classification, utilization, management, and improvement. At the same time, in soil physical and chemical analysis, soilpHIt is closely related to the analysis methods and results of many projects, and therefore serves as a basis for reviewing the results of other projects.
soilpHThe measurement is based on NY/T1121.2-2006 "Soil Testing Part 2: Determination of pH", measured using the glass electrode method. The measurement process includespHCalibration of the meter(pHValue and temperature compensation), weighing10gDry soil sample into a tall beaker, add25ml1Mixing waterWait for 30 minutes to fully disperse the soil particles, then usepHMeasurement and measurement. treatpH
Record the pH value when the reading is stable. Next, remove the electrode, wash it with water, and use a filter paper strip to absorb the moisture before proceeding with the measurement of the next sample. After testing 5-6 samples, a standard solution should be used for inspection.Manually carrying out large-scale operationspH
When analyzing, the operation steps are cumbersome and time-consuming, and attention should be paid to thoroughly washing the electrodes between two measurements. The injection amount of extraction water and extraction time also have a certain impact on the measurement results.the NetherlandsSkalar SP2000soilpHThe analyzer fully automates the above analysis process: it can automatically calibratepHCalculate(pHValue and temperature compensation), automatic addition of leaching solution, automatic stirring to fully disperse soil particles, automatic measurement after 30 minutes, automatic electrode cleaning and regular verification with standard solution during sample measurementpHAutomatically collect measurement data when the stability indicator appears, process and control the data automatically, and generate test reports automatically. This instrument frees the operator from the tedious analysis process, enables unmanned automatic analysis, and solves the deviation caused by differences in subjective consciousness and operational skills of the operator. It can automatically, unmanned, more accurately, quickly, and in large quantities measure soil according to standard methods
