Sampling of soil solution in the systembigReal soil samples are often collected and analyzed using the soaking solution method, which requires a large amount of work and cannot accurately pinpoint the dynamic changes of solutes. Soil solution sampler is an instrument that continuously collects soil solution at a fixed location，Composed of water intake head, sampling bottle, and water intake pump(As shown in the figure)Due to the fact that the water intake head can pass through multiple solutes, when the water intake head is buried in the soil, it can be located and timed to extract soil water/Solution is used to monitor the changes in soil solutes. This method has been widely promoted in fields such as soil fertilizer research, soil pollution, water conservancy departments, and environmental monitoring.

1.The upper opening of the water intake head is glued together10mmProtective head, install two stainless steel pipes separately, and add a sleeve to the surface part.

2.Sampling bottle: The sampling bottle adopts500mlThin mouthed sample bottle, with the bottle mouth sealed with a rubber stopper.

3.Water intake pump: When the water intake pump is connected to the sampling bottle and water intake head, the negative pressure inside the sampling bottle is adjusted according to the soil moisture conditions-30～-80KPA.

4.The equipment configuration includes a water intake head, a water extraction hose, a vent pipe, and a sampling bottle. The material of the hose is a hose with a standard length1.5m，Customized according to length, sampling bottle500ml.

1.The soil solution sampler is equipped with two flexible hoses on the water intake head, one of which is a vent pipe. When the water intake head and the sampling bottle are drawn to a certain negative pressure, the solution around the water intake head will enter the water intake head and the sampling bottle through the water intake head wall. When taking water, first open the vent pipe plug and release air to compress the water in the water intake head. All the water in the water intake head will enter the sampling bottle through the vent pipe to ensure that it does not mix with the next sampling.

2.The soil solution sampler adopts a flexible hose, and the hose buried in the soil can be bent to avoid the wall effect of rapid water infiltration along the hard pipe during rainfall or irrigation.

3.Easy to use, capable of continuous collection of solutions through fixed-point positioning.

4.The surface part of the buried water intake head is equipped with a casing to avoid sun exposure and aging of the hose, extending the service life of the soil solution sampler.

1.The length of time required for sampling a solution and how much water can be extracted under what negative pressure are determined by soil moisture content and soil hydraulic conductivity. Therefore, when the soil moisture is high, the required negative pressure is low and the extraction time is short. Conversely, when the soil moisture is low, the required negative pressure is high and the extraction time is long, even several days.
2.When cleaning the soil solution sampler, a syringe can be used to inject the cleaning solution into the clay tube, and the syringe can be repeatedly used to pump it out. Then, the contaminated liquid can be sucked out and washed multiple times with clean water(No need to dig out clay pipes during cleaning).
