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 resolution varies with temperature, so most nutrient solution analyses are carried out at 20oC.
The higher 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 organic 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 optimum plant development depends on 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 watch EC?

The EC of the nutrient answer impacts the growth and improvement of the plant. In the winter, greater EC is used as a result of it limits water uptake. As a outcome, the cells in the plant do not elongate or “grow” an extreme amount of. They stay smaller and have thicker, stronger cell walls. The plants then look darker, shorter and have smaller leaves. In this case, the plant puts comparatively more power into the formation of flowers and fruits (a manufacturing reaction). If the EC is simply too low underneath poor light situations (i.e. winter), the plant will produce an extreme quantity of leaf growth and too little fruit progress, and will therefore be over-nourished.
Conversely, excessive EC underneath high mild circumstances (summer) will prohibit water uptake too much and thus restrict the plant’s capability to cool itself through transpiration. As a outcome, the crop shall be stressed.
EC also impacts yield and fruit high quality. In basic, larger EC within the root zone environment results in lower yields and smaller fruit dimension. This is because the cells in the fruit take up less water, resulting in lower recent weight. However, larger EC results in higher fruit taste. Therefore, a compromise should be made between fruit high quality, yield, and the nutritional and reproductive development of the crop.
Therefore, it may be very important preserve the correct EC in the root zone surroundings (measured as the distinction between slab EC and drip EC.) The worth of EC varies for every crop type and time of 12 months.
Monitoring EC within the slab

Monitoring EC in plates is a crucial component of weekly diet monitoring and ought to be carried out daily. For a meaningful and accurate evaluation, sampling must be performed in multiple representative plates. Sampling is easy by simply pushing a syringe into the plate and withdrawing a small quantity of nutrient solution (100 ml), which is then placed into the cup of the EC meter for direct reading. The EC values are calculated and plotted on a graph in order that trends may be more easily recognized.
Tips for correct EC measurements with moveable meters

Calibrate the EC meter periodically utilizing a normal resolution.
Check the battery standing, low battery in moveable EC meters is often the cause of errors.
Take measurements on the similar time every day so that outcomes can be interpreted more simply.
Store the meter in a cool, dry place.

What is EC?

Electrical conductivity or “EC” is a measure of the concentration 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 answer varies with temperature, so most nutrient resolution analyses are carried out at 20oC.
The greater the concentration of “total salt” within the substrate, the upper the EC. Inorganic fertilizer ions similar to N, P, K, Ca, Mg, etc. are examples. Urea is an natural molecule and will not 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 progress depends on the crop and variety 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 solution impacts the expansion and growth of the plant. In the winter, larger EC is used as a outcome of it limits water uptake. As a end result, the cells within the plant do not elongate or “grow” an extreme quantity of. They stay smaller and have thicker, stronger cell partitions. 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 too low underneath poor light conditions (i.e. winter), the plant will produce too much leaf growth and too little fruit progress, and can therefore be over-nourished.
Conversely, high EC beneath excessive gentle conditions (summer) will prohibit water uptake too much and thus restrict the plant’s capacity to cool itself by way of transpiration. As a result, the crop will be careworn.
EC also affects yield and fruit quality. In basic, higher EC within the root zone environment results in lower yields and smaller fruit measurement. This is as a outcome of the cells in the fruit take in less water, resulting in decrease fresh weight. However, higher EC leads to higher fruit taste. Therefore, a compromise should be made between fruit high quality, yield, and the dietary and reproductive improvement of the crop.
Therefore, you will need to keep the proper EC within the root zone surroundings (measured because the distinction between slab EC and drip EC.) The worth of EC varies for each crop sort and time of yr.

Monitoring EC in plates is a vital part of weekly nutrition monitoring and ought to be carried out every day. For a significant and correct assessment, sampling ought to be performed in a number of representative plates. Sampling is easy by simply pushing a syringe into the plate and withdrawing a small quantity of nutrient answer (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 developments can be extra easily identified.
