Measurement of the concentration of the working solution of pesticides andfertilizer when spraying in tank mixtures

Reasons for reducing the effectiveness of drugs when spraying:
• Untimely payment.
• Incorrect doses
• Incorrectly adjustedsprayer
• Unfavorable conditions of application
• Use of poor quality water
Where do we get water from?
Well
Lake
River
Pond

What kind of water should there be?
Basic properties of water
Clean water is a myth.
Reservoirs and groundwater always contain dissolved in it: carbonates, bicarbonates, sulfates or nitrates of calcium, magnesium, sodium, potassium, iron, etc.
They give water properties
• rigidity
• pH(//tractor-service.com)

Determination of the total hardness and temperature of the aqueous working solution is the key to the correct operation of pesticides and fertilizers.
When water hardness is more than 400 mg-equiv/l (ppm), some herbicides significantly reduce their effectiveness. And the sediment also clogs the nozzles of the sprayer.гербициды существенно снижают свою эффективность. А осадок еще и забивает форсунки опрыскивателя.
Knowing the concentration of salts in the solution, you will be able to determine the optimal rate of pesticide for the preparation of the working solution, as well as to improve water quality.
How to use:
With the help of this device, you can find out the mg/l (ppm) of the solution in a few seconds. It is only necessary to remove the cover, turn on the device and lower it for a few seconds into the solution, slightly stirring the solution with the device. After 5 seconds, when the readings are established, you can record the readings.
