What is EC?
Electrical conductivity or “EC” is a measure of the focus of “total salt” in a nutrient resolution (drip, plate or drain).
It is expressed as milliSiemens per linear centimeter (mS/cm) or microSiemens per linear centimeter (mS/cm), the place 1mS = 1000µS. pressure gauge 10 bar of a given solution varies with temperature, so most nutrient resolution analyses are carried out at 20oC.
The higher the focus of “total salt” in the substrate, the upper the EC. Inorganic fertilizer ions similar to N, P, K, Ca, Mg, and so on. are examples. Urea is an natural molecule and will not contribute to the EC of the answer as a end result of it does not conduct electricity like calcium (Ca) ions or nitrates. Nitrogen (NO3-N) ions can.
Ec in crops
The EC required for optimal plant growth is decided by the crop and selection grown, the physiological stage of plant development and the prevailing environmental situations inside and outdoors the greenhouse.
Why is it essential to monitor EC?
The EC of the nutrient answer impacts the growth and development of the plant. In the winter, higher EC is used as a end result of it limits water uptake. As a result, the cells in the plant don’t elongate or “grow” too much. They keep smaller and have thicker, stronger cell walls. The plants then look darker, shorter and have smaller leaves. In this case, the plant places comparatively more power into the formation of flowers and fruits (a production reaction). If the EC is simply too low underneath poor mild conditions (i.e. winter), the plant will produce too much leaf growth and too little fruit growth, and can due to this fact be over-nourished.
Conversely, high EC under high light circumstances (summer) will prohibit water uptake too much and thus limit the plant’s capability to chill itself through transpiration. As a end result, the crop shall be confused.
EC additionally affects yield and fruit high quality. In general, greater EC in the root zone surroundings leads to decrease yields and smaller fruit measurement. This is because the cells in the fruit take in much less water, resulting in decrease recent weight. However, greater EC leads to higher fruit taste. Therefore, a compromise must be made between fruit quality, yield, and the dietary and reproductive growth of the crop.
Therefore, it is very important preserve the proper EC within the root zone environment (measured because the distinction between slab EC and drip EC.) The worth of EC varies for each crop kind and time of year.
Monitoring EC in the slab
Monitoring EC in plates is an important part of weekly vitamin monitoring and should be carried out daily. For a meaningful and accurate assessment, sampling ought to be carried out in multiple representative plates. Sampling is easy by merely pushing a syringe into the plate and withdrawing a small quantity of nutrient resolution (100 ml), which is then placed into the cup of the EC meter for direct studying. The EC values are calculated and plotted on a graph in order that tendencies may be extra easily identified.
Tips for accurate EC measurements with transportable meters
Calibrate the EC meter periodically using a normal answer.
Check the battery status, low battery in transportable EC meters is commonly the trigger of errors.
Take measurements at the same time each day in order that results could be interpreted more simply.
Store the meter in a cool, dry place.

Ec in crops
The EC required for optimal plant development depends on the crop and variety grown, the physiological stage of plant development and the prevailing environmental situations inside and out of doors the greenhouse.
Why is it important to monitor EC?
The EC of the nutrient answer affects the growth and growth of the plant. In the winter, larger EC is used as a result of it limits water uptake. As a outcome, the cells in the plant don’t elongate or “grow” an extreme quantity of. They stay smaller and have thicker, stronger cell walls. The vegetation then look darker, shorter and have smaller leaves. In this case, the plant places comparatively extra vitality into the formation of flowers and fruits (a production reaction). If the EC is simply too low underneath poor light situations (i.e. winter), the plant will produce an excessive amount of leaf development and too little fruit growth, and will therefore be over-nourished.
Conversely, excessive EC under high gentle conditions (summer) will limit water uptake an excessive quantity of and thus limit the plant’s capacity to cool itself by way of transpiration. As a outcome, the crop might be careworn.
EC also affects yield and fruit quality. In common, larger EC in the root zone surroundings results in decrease yields and smaller fruit measurement. This is as a result of the cells within the fruit absorb less water, leading to lower fresh weight. However, higher EC leads to higher fruit taste. Therefore, a compromise have to be made between fruit high quality, yield, and the nutritional and reproductive improvement of the crop.
Therefore, it is important to keep the proper EC in the root zone setting (measured as the distinction between slab EC and drip EC.) The value of EC varies for every crop kind and time of 12 months.
Monitoring EC in the slab
Monitoring EC in plates is a vital part of weekly diet monitoring and should be carried out day by day. For a significant and accurate evaluation, sampling should be performed in a number of consultant plates. Sampling is straightforward by merely pushing a syringe into the plate and withdrawing a small amount of nutrient solution (100 ml), which is then positioned into the cup of the EC meter for direct reading. The EC values are calculated and plotted on a graph so that developments can be extra simply recognized.
Tips for correct EC measurements with moveable meters
Calibrate the EC meter periodically utilizing a standard resolution.
Check the battery status, low battery in transportable EC meters is often the reason for errors.
Take measurements on the similar time every day in order that results may be interpreted more easily.
Store pressure gauge 10 bar in a cool, dry place.
