What is EC?
digital pressure gauge or “EC” is a measure of the concentration of “total salt” in a nutrient answer (drip, plate or drain).
It is expressed as milliSiemens per linear centimeter (mS/cm) or microSiemens per linear centimeter (mS/cm), where 1mS = 1000µS. The conductivity of a given resolution varies with temperature, so most nutrient answer analyses are performed at 20oC.
The higher the concentration of “total salt” in the substrate, the upper the EC. Inorganic fertilizer ions corresponding to N, P, K, Ca, Mg, and so on. are examples. Urea is an organic molecule and received’t contribute to the EC of the answer because it doesn’t conduct electrical energy 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 improvement and the prevailing environmental situations inside and out of doors the greenhouse.
Why is it important to observe EC?
The EC of the nutrient resolution affects the growth and development of the plant. In the winter, greater EC is used as a result of it limits water uptake. As a outcome, the cells within the plant don’t elongate or “grow” an excessive amount of. They keep smaller and have thicker, stronger cell partitions. The vegetation then look darker, shorter and have smaller leaves. In this case, the plant places relatively extra energy into the formation of flowers and fruits (a manufacturing reaction). If the EC is simply too low beneath poor mild circumstances (i.e. winter), the plant will produce an extreme quantity of leaf progress and too little fruit development, and will therefore be over-nourished.
Conversely, high EC under high mild situations (summer) will limit water uptake too much and thus limit the plant’s ability to chill itself via transpiration. As a result, the crop will be confused.
EC additionally impacts yield and fruit high quality. In general, higher EC in the root zone setting results in decrease yields and smaller fruit measurement. This is as a result of the cells within the fruit take in much less water, resulting in lower fresh weight. However, greater EC leads to better fruit flavor. Therefore, a compromise have to be made between fruit high quality, yield, and the dietary and reproductive growth of the crop.
Therefore, it is necessary to maintain the right EC in the root zone setting (measured because the difference between slab EC and drip EC.) The worth of EC varies for every crop kind and time of yr.
Monitoring EC within the slab
Monitoring EC in plates is a vital part of weekly vitamin monitoring and ought to be performed every day. For a significant and correct assessment, sampling ought to be carried out in multiple 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 in order that developments could be extra simply identified.
Tips for accurate EC measurements with portable meters
Calibrate the EC meter periodically utilizing a regular solution.
Check the battery status, low battery in moveable EC meters is commonly the purpose for errors.
Take measurements on the identical time each day in order that results may be interpreted more simply.
Store the meter in a cool, dry place.

Ec in crops
The EC required for optimum plant development is dependent upon the crop and selection grown, the physiological stage of plant improvement and the prevailing environmental conditions inside and outside the greenhouse.
Why is it essential to monitor EC?
The EC of the nutrient resolution affects the growth and development of the plant. In the winter, greater EC is used as a result of it limits water uptake.

If the EC is too low beneath poor light circumstances (i.e. winter), the plant will produce an excessive amount of leaf development and too little fruit development, and will subsequently be over-nourished.
Conversely, high EC beneath excessive gentle situations (summer) will prohibit water uptake too much and thus limit the plant’s ability to cool itself via transpiration. As a end result, the crop shall be stressed.
EC also affects yield and fruit quality. In common, higher EC within the root zone environment results in decrease yields and smaller fruit dimension. This is because the cells within the fruit take in much less water, resulting in lower recent weight. However, higher EC results in better fruit flavor. Therefore, a compromise should be made between fruit quality, yield, and the nutritional and reproductive development of the crop.
Therefore, it is important to maintain the proper EC in the root zone setting (measured because the difference between slab EC and drip EC.) The worth of EC varies for each crop kind and time of year.
Monitoring EC within the slab
Monitoring EC in plates is a crucial part of weekly vitamin monitoring and must be carried out day by day. For a meaningful and correct assessment, sampling should be performed in multiple representative plates. Sampling is straightforward by simply pushing a syringe into the plate and withdrawing a small quantity of nutrient resolution (100 ml), which is then positioned into the cup of the EC meter for direct studying. The EC values are calculated and plotted on a graph in order that trends may be extra simply identified.
Tips for correct EC measurements with portable meters
Calibrate the EC meter periodically using a standard answer.
Check the battery standing, low battery in transportable EC meters is often the cause of errors.
Take measurements on the identical time each day so that results may be interpreted more simply.
Store the meter in a cool, dry place.
