What is EC?

Electrical conductivity or “EC” is a measure of the focus 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 resolution analyses are performed at 20oC.
The higher the focus of “total salt” within the substrate, the upper the EC. Inorganic fertilizer ions such as N, P, K, Ca, Mg, and so on. are examples. Urea is an organic molecule and gained’t contribute to the EC of the solution 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 development depends on the crop and selection grown, the physiological stage of plant development and the prevailing environmental circumstances inside and outside the greenhouse.
Why is เกจวัดแรงดัน to observe EC?

The EC of the nutrient solution affects the expansion and improvement of the plant. In the winter, larger EC is used as a outcome of it limits water uptake. As a result, the cells in the plant do not elongate or “grow” an excessive quantity of. They stay 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 power into the formation of flowers and fruits (a production reaction). If the EC is merely too low under poor light situations (i.e. winter), the plant will produce too much leaf growth and too little fruit progress, and will subsequently be over-nourished.
Conversely, high EC underneath high light conditions (summer) will prohibit water uptake an extreme quantity of and thus restrict the plant’s capability to chill itself by way of transpiration. As a outcome, the crop might be careworn.
เกจวัดแรงดัน yield and fruit high quality. In basic, greater EC in the root zone setting results in lower yields and smaller fruit size. This is because the cells in the fruit absorb much less water, leading to lower fresh weight. However, greater EC results in better fruit taste. Therefore, a compromise must be made between fruit high quality, yield, and the nutritional and reproductive development of the crop.
Therefore, it could be very important keep the right EC in the root zone environment (measured because the difference between slab EC and drip EC.) The value of EC varies for each crop sort and time of yr.
Monitoring EC within the slab

Monitoring EC in plates is an important component of weekly diet monitoring and should be carried out every day. For a significant and accurate assessment, sampling must be carried out in a number of representative plates. Sampling is simple by merely pushing a syringe into the plate and withdrawing a small quantity of nutrient resolution (100 ml), which is then placed into the cup of the EC meter for direct studying. The EC values are calculated and plotted on a graph in order that developments can be more simply recognized.
Tips for accurate EC measurements with portable meters

Calibrate the EC meter periodically utilizing a normal answer.
Check the battery status, low battery in moveable EC meters is often the cause for errors.
Take measurements at the similar time each day in order that results could be interpreted extra simply.
Store the meter in a cool, dry place.

Ec in crops

The EC required for optimum plant progress is dependent upon the crop and selection grown, the physiological stage of plant growth and the prevailing environmental conditions inside and out of doors the greenhouse.
Why is it essential to monitor EC?

The EC of the nutrient resolution impacts the expansion and growth of the plant. In the winter, higher EC is used because it limits water uptake. As a result, the cells within the plant don’t elongate or “grow” an extreme amount of. They stay smaller and have thicker, stronger cell partitions. The vegetation then look darker, shorter and have smaller leaves. In this case, the plant places comparatively extra energy into the formation of flowers and fruits (a production reaction). If the EC is just too low underneath poor mild situations (i.e. winter), the plant will produce an excessive amount of leaf growth and too little fruit growth, and will therefore be over-nourished.
Conversely, high EC beneath high gentle circumstances (summer) will restrict water uptake an excessive quantity of and thus limit the plant’s capability to cool itself via transpiration. As a end result, the crop will be confused.
EC also impacts yield and fruit quality. In general, higher EC within the root zone environment leads to lower yields and smaller fruit size. This is because the cells within the fruit take up less water, resulting in lower fresh weight. However, larger EC results in better fruit flavor. Therefore, a compromise have to be made between fruit quality, yield, and the dietary and reproductive growth of the crop.
Therefore, it may be very important keep the correct EC within the root zone environment (measured because the distinction between slab EC and drip EC.) The value of EC varies for every crop sort and time of yr.
Monitoring EC within the slab

Monitoring EC in plates is an important part of weekly nutrition monitoring and must be performed daily. For a meaningful and correct evaluation, sampling should be performed in a number of consultant plates. Sampling is straightforward by merely pushing a syringe into the plate and withdrawing a small amount 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 developments can be more simply identified.
