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 carried out at 20oC.
The higher the concentration of “total salt” within the substrate, the higher the EC. Inorganic fertilizer ions corresponding to N, P, K, Ca, Mg, etc. are examples. pressure gauge is an natural molecule and will not contribute to the EC of the answer because it doesn’t conduct electricity 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 growth and the prevailing environmental conditions inside and outdoors the greenhouse.
Why is it important to monitor EC?
The EC of the nutrient answer impacts the expansion and development of the plant. In the winter, larger EC is used as a outcome of it limits water uptake. As a outcome, the cells within the plant do not 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 merely too low beneath poor mild situations (i.e. winter), the plant will produce an excessive quantity of leaf development and too little fruit development, and will due to this fact be over-nourished.
Conversely, excessive EC underneath high gentle conditions (summer) will limit water uptake an extreme quantity of and thus restrict the plant’s capacity to cool itself by way of transpiration. As a result, the crop will be stressed.
EC additionally affects yield and fruit high quality. In common, greater EC in the root zone surroundings leads to decrease yields and smaller fruit measurement. This is because the cells in the fruit absorb less water, leading to lower recent weight. However, larger EC results in better fruit taste. Therefore, a compromise have to be made between fruit quality, yield, and the nutritional and reproductive development of the crop.
Therefore, it is necessary to preserve the correct EC in 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 year.
Monitoring EC in the slab
Monitoring EC in plates is an important component of weekly nutrition monitoring and must be performed every day. For a significant and accurate assessment, sampling should be performed in multiple representative plates. Sampling is simple by merely 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 so that trends could be extra easily recognized.
Tips for correct EC measurements with portable meters
Calibrate the EC meter periodically utilizing a standard solution.
Check the battery standing, low battery in transportable EC meters is commonly the purpose for errors.
Take measurements on the similar time each day in order that results may be interpreted extra easily.
Store the meter in a cool, dry place.

The EC required for optimum plant progress is decided by the crop and variety grown, the physiological stage of plant development and the prevailing environmental circumstances inside and outdoors the greenhouse.
Why is it essential to observe EC?
The EC of the nutrient resolution affects the growth and development of the plant. In the winter, larger EC is used because it limits water uptake. As a end result, the cells in 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 puts relatively extra power into the formation of flowers and fruits (a production reaction). If ไดอะแฟรม is too low under poor gentle conditions (i.e. winter), the plant will produce an extreme amount of leaf progress and too little fruit development, and can therefore be over-nourished.
Conversely, high EC underneath excessive light circumstances (summer) will restrict water uptake too much and thus restrict the plant’s ability to chill itself through transpiration. As a end result, the crop will be careworn.
EC additionally impacts yield and fruit quality. In general, larger EC within the root zone environment leads to decrease yields and smaller fruit measurement. This is because the cells in the fruit take in less water, resulting in lower contemporary weight. However, larger EC results in higher fruit taste. Therefore, a compromise should be made between fruit high quality, yield, and the dietary and reproductive improvement of the crop.
Therefore, it is necessary to preserve the proper EC within the root zone setting (measured as the difference between slab EC and drip EC.) The value of EC varies for every crop sort and time of year.
