I am both interested in knowing the number when I have just given them fertilizer, but also in being able to read the values as the soil loses the values, as I run regular routines with application of fertilizer every 4 days, it can be crucial that there is no accumulates too much "old manure" in the soil and especially in the last stage of flowering, it is important that the soil is depleted of nutrients so that it can go into the compost after harvest. I think I can make a chart that can convert the values that come out when measuring directly into the ground. we just need to know the extent of the mass of soil and the amount of water that is in the pot and then equalize the difference between 100% water and soil that is 100% saturated with water and then put the values into a chart. it is a bit cumbersome and a tedious task, but in return, it is only necessary to do the process once.
Hi Jason! Great video! I was wondering though how much water do you put through your pour method to have an accurate idea of the conductivity of your soil? It seems to me there's a fine line of not putting enough water and putting to much to have an accurate reading?
Hi George - that's true, and I think most instructions are to target a small amount of leachate (like 50ml). Not sure how easy it is to be so consistent.
It depends on how much your plants are using, how often you apply, whether you alternate with a flush of plain water. Salt can definitely build up in the pot if you fertilize with every watering. It's a good idea to verify the EC in your pot with a pour-through test occasionally to see where you're at.
Hi Jason, Found the thread! Hope your well. I have a EC meter that reports in us/cm - the water we use to feed our plants is 240 on the EC i'm not sure how to calculate this into a 2.4 for example number yourself and many other online resources seem to. Online calculators are confusing me more lol. We have an inline fertigation system which is brand new so still working it out but I assumed the numbers to be higher too with that dripping feed into the system all the time. Thanks
My estimate on this was only made with observation in soil on *that* particular meter, and I think I may have noted (though it's been a long time) that it's far more accurate to perform measurement using the pour-through method. Yes, the conversion from 240 to 2.4 sounds about right - as there's some inconsistency between meters that report in different units (or even convert over to an estimated ppm).
@@FraserValleyRoseFarm Thanks for the reply, yes the pour through is 1500 so now I’m thinking the irrigation water is way to low which questions if our fertigation system is actually doing much….i was thinking that our base soil for propagation is rather sterile so should have a low ec so our water with fert should hit the target range we need. Our range for dahlias is 100-200ppm N, EC extraction 0.4-0.9mS/cm, SME: 0.9-2.0mS/cm and pour 1.3-3.0mS/cm according to Michigan State paper they released. Do you know how I convert these to us/cm that my read gives me? Thanks so much! I’m not a numbers person the best of times!!
Hey Jason - thanks for the video and I realise it is old and you may not be reading the comments anymore. I wondered how moist the soil should be for direct reading, in order for the factor of 4 estimate to be roughly applicable? Does soil moisture not influences this? While I'm here, I was a little baffled as to why you showed the leachate reading without also taking a direct reading of that same soil, so you could demonstrate on camera the factor of 4 tip. You walked away from the leachate reading plant and stuck the meter in a bunch of other pots... so just flagging an odd missed opportunity there to demonstrate directly what I think is the central information you're sharing here: the factor of 4 estimate tip for converting a direct reading into an estimate reading of leachate conductivity.
Thanks. Probably a little bit of inexperience showing on my parts (not to demonstrate the conversion) - and frankly, it ended up as a pretty iffy topic for TH-cam, given how difficult it is to explain, and how few viewers take an interest. Live and learn! You're right that the soil moisture makes a big difference, and for that reason I try to be relatively consistent in my timing - usually on the morning after a watering is pretty good, and the soil is evenly moist in the pots. Some "thristy" and rootbound crops are more difficult to gauge.
This test can only let you know the total amount of mineral salts, not any specific nutrients. I try to apply a generally balanced fertilizer, and that usually is okay, but if you need more specific analysis, you'll have to go to a soil lab.
Only by experience - as a comparison between measurement in liquid solution and in moist potting soil. You can do it without the "translation" just fine, you just have to change your own benchmarks of what's an acceptable reading.
Hi Mini - spend your money how you want. For me, it work as a much faster, more convenient alternative to the pour-through method. The meter reads exactly the EC of a water solution - no problem there, but when you use it in soil, the number is lower (because conductivity is lower in soil). You don't have to do the x4 calculation at all - I just know that when it reads .7 and above, I have a high fertilizer release in the crop. Your criticism of accuracy is valid (it depends a lot on soil moisture), but for me it's not a question of perfectly accurate, but whether it's *accurate enough* for my purposes. A quick walk around the nursery and I can test many dozens of crops. On several occasions, it's helped me to identify excess fertilizer release in unexpected crops (which I then confirmed with pour-through) - the point being that it would take me many hours to screen what I can in 15 minutes if I were to use the more accurate method right up front.

Sir what is the perfect ec rate requirment of roses
Is 1.6 to 1.8 ok??
Those rates are okay, even up to 2.2 or so.
Suppose my fertilizer has EC 2.5 when it is applied to the soil. How much is EC in soil ?

@@FraserValleyRoseFarm Thanks so much for the reply. I'll do what you do then, in terms of when to take the reading after watering! All the best.
Important topic and nice explanation. Thank you!05.07.24
What if reading comes below minimum?. I mean how to detect the which nutrient is missing?
This test can only let you know the total amount of mineral salts, not any specific nutrients. I try to apply a generally balanced fertilizer, and that usually is okay, but if you need more specific analysis, you'll have to go to a soil lab.
@@FraserValleyRoseFarm thank u sir for your reply
Why the result should be x 4 ?
Only by experience - as a comparison between measurement in liquid solution and in moist potting soil. You can do it without the "translation" just fine, you just have to change your own benchmarks of what's an acceptable reading.
Dude, why would I spend money on this gadget when I still have to ×4 the reading. Does not sound accurate at all.

Soil and water reading not in the same range . Soil ec metre read salinity in the medium.
Invest in a truncheon.
But I'm not even hungry!
That was my porn name Direct Stick
😁😆😂😂
I can tell by looking at how green a plant is I don't need gadgets.
The gadgets allow you to detect problems before they cause alterations of the green color.
Gree mean everythings ok. If not green,then you start wondering why.
