A specific question for the laboratory examination
The water test is not just the purchase of a document when preparing a greenhouse construction. The test purpose shall be assigned to the intended production and water system. We are looking for another question if we look at the suitability of the source, check the results of a treatment or follow the condition of a recirculated water. Before sampling, the customer shall check with the water technology and cultivation specialist what decision he expects of the result. The scope of the tests requested therefore follows for use. A previous lab page for other purposes does not necessarily answer the new greenhouse design questions.
Place and date of sample
To interpret the results of the laboratory, you should know where and in what condition the sample was taken. The sample taken from the source, from a container and from the end of the irrigation system may show different system boundaries. If this does not come out from the document, the result is later difficult to relate to real operation. The method of sampling and the conditions of transport shall be agreed for the test to be carried out. The change in the water source in time is also a specific issue: a momentary figure and the situation typical of the production season are not the same. In addition to the measured result, the conditions of sampling should therefore remain in the design fund.
Select not immediately from the result
A detected derogation does not automatically designate a single water treatment device. First, it is necessary to clarify which use requirement is a problem and which point of intervention is required. The expected condition after treatment should also be stated. M FAO the production guide and Dalsem The water system approach provides a professional background for water and plant relations. However, the local technical solution should be derived from the combined interpretation of the specific laboratory result, quantitative demand and the chosen method of cultivation. The offer should therefore also record the starting data used and the limit of treatment undertaken.
The decision of an interpreted data sheet is useful
A good working document for the investor may be a short sheet, which, in addition to the measured values, shall specify the system task concerned and the additional question. The expert performing the interpretation shall be identifiable and shall include a specific need for certain data, assumptions and new testing. The developer can see from this which technology is designed for pipework systems, storage and treatment points. If other sources of water or different cultivation are later included, this page shall also be updated. The document will remain the basis of the decision, not a forgotten annex.
The check shall continue at the start of operation
When preparing the transfer, it can be determined where and when the water status of the system is checked. The test shall mean the same system limit as the undertaking. If a new element or modified route has been created in the internal distribution, it should also be recognised in the verification. The operator knows when to retest and who to check for unusual results. The operational measurement and the laboratory test may support each other, but none shall be understood without the sampling site, time and use. Therefore, the system data and test document should remain available together.
Questions to reconcile the project
- What kind of planning or operation are we expecting from the lab test?
- Does the sampling site and condition meet this question?
- Who interprets the measured result for the planned plant and water technology?
