What is soft water? What is hard water?
What are the characteristics of soft water? What are the characteristics of hard water? Why can't you use hard water to dilute pesticides? The following farming help planting network is briefly introduced for netizens' reference. Water can be divided into hard water and soft water. The so-called hard water refers to water such as well water, salt water, sea water, etc., which contains more calcium, magnesium and other substances, with a hardness of 18 to 20 degrees. Soft water refers to fresh water such as river and lake water, which contains less calcium and magnesium, and its hardness is about 7.5 degrees. The main reason why hard water can not be used to dilute pesticides is that calcium, magnesium and other substances in water can reduce the suspension rate of wettable agents or synthesize calcium and magnesium precipitates with emulsification in EC, thus destroying the emulsifying performance of EC. This will not only reduce the prevention and control effect of pesticides, but also produce drug damage. The soft water contains less calcium, magnesium and other substances, it will not destroy the performance of the agent and reduce the control effect.
