What is EC?
Electrical conductivity or “EC” is a measure of the focus of “total salt” in a nutrient solution (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. The conductivity of a given solution varies with temperature, so most nutrient resolution analyses are performed at 20oC.
The larger the focus of “total salt” in the substrate, the upper the EC. Inorganic fertilizer ions such as N, P, K, Ca, Mg, and so forth. are examples. Urea is an natural molecule and won’t contribute to the EC of the solution because it does not conduct electrical energy like calcium (Ca) ions or nitrates. Nitrogen (NO3-N) ions can.
Ec in crops
The EC required for optimum plant growth is dependent upon the crop and variety grown, the physiological stage of plant development and the prevailing environmental conditions inside and out of doors the greenhouse.
Why is it essential to observe EC?
The EC of the nutrient solution affects the expansion and development of the plant. In the winter, higher EC is used because it limits water uptake. As a result, the cells within the plant do not elongate or “grow” too much. They keep smaller and have thicker, stronger cell walls. The crops then look darker, shorter and have smaller leaves. In this case, the plant puts comparatively extra energy into the formation of flowers and fruits (a manufacturing reaction). If the EC is just too low beneath poor gentle circumstances (i.e. winter), the plant will produce too much leaf progress and too little fruit progress, and will therefore be over-nourished.
Conversely, high EC beneath excessive light situations (summer) will restrict water uptake an extreme quantity of and thus restrict the plant’s capacity to chill itself via transpiration. As a result, the crop will be careworn.
EC also impacts yield and fruit high quality. In common, greater EC in the root zone surroundings results in decrease yields and smaller fruit size. This is as a outcome of the cells within the fruit take up much less water, leading to decrease fresh weight. However, higher EC leads to better fruit flavor. Therefore, a compromise have to be made between fruit high quality, yield, and the nutritional and reproductive improvement of the crop.
Therefore, it may be very important keep the proper EC in the root zone setting (measured because the distinction between slab EC and drip EC.) The value of EC varies for each crop type and time of year.
Monitoring EC within the slab
Monitoring EC in plates is a vital component of weekly vitamin monitoring and should be performed daily. For a meaningful and correct assessment, sampling must be performed in a quantity of consultant plates. Sampling is simple 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 studying. The EC values are calculated and plotted on a graph so that trends may be extra easily recognized.
Tips for correct EC measurements with portable meters
Calibrate the EC meter periodically using a normal answer.
Check the battery status, low battery in portable EC meters is often the reason for errors.
Take measurements at the similar time each day in order that results could be interpreted more easily.
Store the meter in a cool, dry place.

Electrical conductivity or “EC” is a measure of the concentration of “total salt” in a nutrient resolution (drip, plate or drain).

Ec in crops
The EC required for optimum plant development is dependent upon the crop and selection grown, the physiological stage of plant development and the prevailing environmental conditions inside and outdoors the greenhouse.
Why is it important to watch EC?
The EC of the nutrient answer affects the expansion and growth of the plant. In the winter, greater EC is used because it limits water uptake. As a end result, the cells within the plant don’t elongate or “grow” an extreme amount of. They keep smaller and have thicker, stronger cell walls. The vegetation then look darker, shorter and have smaller leaves. In this case, the plant places relatively extra vitality into the formation of flowers and fruits (a production reaction). If the EC is too low underneath poor light situations (i.e. winter), the plant will produce too much leaf development and too little fruit growth, and can therefore be over-nourished.
Conversely, excessive EC beneath high light situations (summer) will limit water uptake an excessive amount of and thus limit the plant’s capability to chill itself via transpiration. As a end result, the crop will be careworn.
EC additionally impacts yield and fruit high quality. In common, larger EC within the root zone environment results in lower yields and smaller fruit size. This is as a outcome of the cells within the fruit take in less water, leading to decrease recent weight. However, greater EC results in higher fruit flavor. Therefore, a compromise should be made between fruit quality, yield, and the dietary and reproductive improvement of the crop.
Therefore, it is very important preserve the right EC within the root zone surroundings (measured as the distinction between slab EC and drip EC.) The value of EC varies for each crop type and time of yr.
