Whole of soil water samplers
The soil water sampler is an apparatus by which it is possible to draw a sample of the solution of the soil out of the roots of the plants. Since the solution contains dissolved fertilizers and various salts that may accumulate in it during the season of the cultivation, it is necessary to examine the composition of the solution from time to time in order to ascertain that we are on the right track. The principle of operation: a) A porous ceramic at the end of the soil water sampler absorbs the solution from the soil; b) Sub-pressure is created (vacuum) in the chamber of the soil water sampler by means of a plastic syringe. After a certain period of time, the water is absorbed into the syringe, through the ceramic, and from it to the test tube, in order to carry out different analyses of the water. When to carry out a drawing? It is accepted to ready the apparatus shortly after irrigating when the soil is wet. This period of time depends on a number of factors, such as: the depth of the roots and the type of soil. It is recommended to consult with the agronomist or the agricultural guide in regards to this. The sucking of the solution into the syringe shall be carried out after the readying.
Components of the whole
Porous ceramic with a thread, a 20 mm PVC tube, upper rubber cap, a thin tube inserted into the cap, a 3-directional small faucet, a plastic syringe for creating a vacuum.
Optional Technical Specification
Since the goal is to suck a solution of the soil just as the plant does, we shall want to suck it out of the roots of the plant. Therefore, we suggest standard lengths (optional): 20/30/40/60/90 cm. It is also possible to choose in accordance with the type of soil (light or heavy) the desired length of the ceramic: 6 or 12 cm, or to receive an angular soil solution sampler in order to easily suck the soil solution of the plants that are planted on a detached substrate.
General Comments
- What are the most common chemical tests? There exist different test kits by means of which it is possible to carry out simple tests with no need for a laboratory and special expensive instruments. The accepted tests are those for: Chloride, potassium, EC, pH, NO2-NO3. Other tests such as tests for dissolved oxygen and other substances can be carried out in a laboratory. How to tackle the results of the tests? Every crop and every type of soil has its own requirements for consuming fertilizers and different resistance to salts and there is need to analyze the results in accordance with the existing knowledge. It is recommended to consult with an agronomist or a guide. What matters is to carry out an ongoing follow up in order to detect changes that occur during the period of the cultivation. For instance, it is possible to find accumulation of salt as a result of under-irrigation or an impoverishing of the elements of the fertilizer as a result of faulty fertilization or over-consumption and vice versa, an increase in the minerals as a result of over-fertilization.
- Soil with different characteristics, such as: Depths that are different from the standard and the like. In order to receive an offer for a product with unique characteristics, you have to file a request with the Company and we will make an offer accordingly.
