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. The conductivity of a given answer varies with temperature, so most nutrient resolution analyses are performed at 20oC.
The larger the concentration 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 will not contribute to the EC of the answer as a result of 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 development is dependent upon the crop and selection grown, the physiological stage of plant growth and the prevailing environmental conditions inside and outdoors the greenhouse.
Why is it important to monitor EC?

The EC of the nutrient solution impacts the expansion and growth of the plant. In the winter, higher EC is used because it limits water uptake. As a outcome, the cells within the plant do not elongate or “grow” too much. They stay smaller and have thicker, stronger cell partitions. The crops then look darker, shorter and have smaller leaves. In this case, the plant places relatively more energy into the formation of flowers and fruits (a production reaction). If the EC is just too low beneath poor mild situations (i.e. winter), the plant will produce too much leaf progress and too little fruit development, and can therefore be over-nourished.
Conversely, high EC underneath excessive mild circumstances (summer) will limit water uptake an extreme amount of and thus restrict the plant’s ability to cool itself via transpiration. As a result, the crop will be careworn.
EC also affects yield and fruit quality. In general, larger EC within the root zone environment results in decrease yields and smaller fruit measurement. This is as a result of the cells within the fruit take up less water, leading to lower contemporary weight. However, higher EC results in better fruit flavor. Therefore, a compromise have to be made between fruit high quality, yield, and the nutritional and reproductive development of the crop.
Therefore, you will want to keep the correct EC in the root zone surroundings (measured as the difference between slab EC and drip EC.) The value of EC varies for every crop sort and time of 12 months.
Monitoring EC in the slab

Monitoring EC in plates is a vital element of weekly vitamin monitoring and must be performed daily. For a meaningful and accurate assessment, sampling ought to be performed in a quantity of representative plates. Sampling is easy by simply pushing a syringe into the plate and withdrawing a small amount of nutrient answer (100 ml), which is then placed into the cup of the EC meter for direct reading. pressure gauge 4 นิ้ว are calculated and plotted on a graph in order that tendencies could be more simply identified.
Tips for correct EC measurements with portable meters

Calibrate the EC meter periodically utilizing a normal solution.
Check the battery status, low battery in portable EC meters is often the cause of errors.
Take measurements on the identical time each day so that outcomes can be interpreted more easily.
Store the meter in a cool, dry place.

Why is it important to watch EC?

The EC of the nutrient solution impacts the expansion and development of the plant. In the winter, larger EC is used because it limits water uptake. As a outcome, the cells within the plant don’t elongate or “grow” too much. They keep smaller and have thicker, stronger cell walls. The vegetation then look darker, shorter and have smaller leaves. In this case, the plant puts comparatively extra vitality into the formation of flowers and fruits (a production reaction). If the EC is merely too low beneath poor light circumstances (i.e. winter), the plant will produce too much leaf progress and too little fruit development, and can due to this fact be over-nourished.
Conversely, excessive EC underneath excessive mild situations (summer) will limit water uptake too much and thus limit the plant’s ability to chill itself through transpiration. As a result, the crop might be careworn.
EC also affects yield and fruit high quality. In basic, larger EC in the root zone setting leads to decrease yields and smaller fruit measurement. This is because the cells within the fruit take up much less water, leading to lower contemporary weight. However, higher EC results in better fruit taste. Therefore, a compromise have to be made between fruit high quality, yield, and the nutritional and reproductive development of the crop.
Therefore, you will need to keep the correct EC within the root zone setting (measured as the distinction 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 crucial element of weekly diet monitoring and should be performed day by day. For a meaningful and correct evaluation, sampling should be performed in a number of consultant plates. Sampling is simple by simply pushing a syringe into the plate and withdrawing a small quantity 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 could be more easily recognized.
Tips for correct EC measurements with portable meters

Calibrate the EC meter periodically using a regular answer.
Check the battery standing, low battery in transportable EC meters is commonly the purpose for errors.
Take measurements on the same time each day so that outcomes may be interpreted extra simply.
