Testing Soil Texture - Mason Jar Soil Test

[@ShelljetA1]

Excellent video Sir! I am currently studying horticulture your description of the process is spot on.

[@growitbuildit]

Thank you! I try to be as accurate and informative as I can.

[@zayinkaph]

This is outstanding sir. Thank you! I was wondering if there was a simple way to test my OK clay soil AND drainage without having to spend a ton of money. Perfect information I can use and run with!!

[@growitbuildit]

You are welcome! Good luck figuring out your texture! For improving your soil, I strongly suggest you watch my leaf mulch videos. I've been doing it for four years, documenting the improvements to top-soil depth. This was the first one - kzbin.info/www/bejne/oaq8oXqEj7R2rac

@@growitbuildit how exactly do you make use of the usda to determine the soil type. Been struggling

[@growitbuildit]

Hi - you have to follow on the triangle, or use their calculator for determining the exact type. The soil type is directly applicable to construction projects, depending on what you are building. For gardening it has implications for potential fertility & nutrients. For reading the USDA soil triangle, you just have to follow the lines. Or use the calculator by entering in 2 of the %'s. www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/survey/tools/?cid=nrcs142p2_054167 Clay is represented on the Right Side, by horizontal lines. Sand is represented on the bottom, from lines that run from the bottom up and to the left (to the clay side). Silt is on the right side of the triangle, and runs down to the sand. If you look at the angle the 'numbers' are, they correspond to lines that run the same direction. You just need to find where the lines all cross, or at least get as close as you can. Then you can see what the area is represented as.

[@she_sows_seeds]

Thank you for the info! I've recently moved house and I want to start planning what to plant where but first I'm going to test the soil and see what I'm working with. I'm trying to avoid having to lift my dahlias every year so aiming for an area that isn't clay heavy etc. I wasn't sure how to go about it but your video has made me confident I can test accurately. Thanks!

[@growitbuildit]

Excellent - I'm glad I could help you out!

[@theorphanedchicken1839]

I drew a line at the silt layer after 2 hours, but it’s been about a day now and the silt sank below the line I drew. Do I just measure the clay that’s above the silt line I drew?

[@growitbuildit]

That seems odd that it sank. Did you sift it through a kitchen strainer? I would record these results, but then would probably repeat the test, making sure it is really sifted and mixed.

[@doubleupgut]

Adding calcium will help structure compacted clay soils and increase aerobic bacteria and fungi. This is also why dandelions show up in dense clay soils in a attempt to bio-accumulate the calcium trapped deep beneath the top soil.

[@OffGridHawaii]

Best video I’ve seen on this topic. Mahalo

[@growitbuildit]

Thank you!

[@KaidaMizu]

If you mark 50mm on the jar and fill it with soil to that line then you only need to wait for the sand and silt to settle. You measure them, double the measurements gives you the percentage and whatever percentage is left must be the clay.

[@growitbuildit]

That sounds right. I don't think anything should swell up. Your comment is a time saver.

[@shannongood8598]

Thank you for this excellent video! I really appreciate your getting to the information without a bunch of obnoxious music and unnecessary video footage. That just takes up time without giving us what we're here for. It seems to be the norm, unfortunately. I have a question about taking soil samples in wet weather. Here is Western Washington, the soils are saturated for 4-5 months. I'm planning a drip irrigation system and my first step is determining my soil structure. Should I dry my soil samples before sieving to get more accurate results? I'd like to get the sampling done now, since it's too wet to do any work outside. Thanks again!

[@growitbuildit]

Hi Shannon - I think your idea is a good one. Drying the soils should make sieving the soils easier.

[@paulanderson2631]

I have raised beds and when doing test I had 1/4" of sand and 3" of black/brown sediment clear water with a few floating particles? I assume the brown black layer is old peat and compost?

[@growitbuildit]

Hi - yes, that is most likely what it is.

[@firstdonuts]

did everything as you did. I just get one uniform conglomerate of soil. Im not sure if im looking at clay, sand, or silt, but its all the same eith water on top.

[@growitbuildit]

If it only took a minute to settle, then it is probably sand. If the level didn't settle for longer, then it is probably silt or clay

[@firstdonuts]

@growitbuildit So I just opted to do it again. And perhaps this can serve as a little pointer for other people. I think I made the mistake of sifting my soil too much. My soil does have fine particulates when you dig it up, but the majority of the soil is actually small clumps that I was sifting out entirely. So I'm guessing that by doing this, I was essentially sifting out the clay and sand that is mostly found in the small compact lumps of soil. After doing it again, and keeping the compact clumps of dirt (which break apart when you shake it anyways) I can now see a very clear separation of sand, silt, and a tiny bit of clay on top. 👍 Ty for the video mate. On my way to making a beautiful garden

[@growitbuildit]

Thanks for repeating the test. I agree that your results will likely help others. Good luck!

[@sumer122889]

Amazing video. Explained simply and directly without talking about all the unnecessary bits. I have one question tho, can the same test be done using powdered laundry detergent?

[@growitbuildit]

Hi Sumer - first, thank you for the kind words! I am not sure if powdered laundry detergent would work. They are different types of soap. One person in these comments used liquid laundry detergent and ended up with a gooey mess. That being said, regular liquid soap for dish washing may work ok, as it is a bit lighter.

[@CC-vr6fm]

Hello ! Is it possible to perform the test without detergent ? I am worried about the ecological impact of the detergent

[@growitbuildit]

The detergent helps get everything separated. You could try to find some biodegradable granular soap - not sure how well it would work, but should be better for environment.

[@TinyGem]

Beautiful... I learnt a lot

[@growitbuildit]

That was my goal. I'm glad I could help you out!

[@codallthetime7045]

ours is in dishwashing liquid and mine have started to bubble like aloottt of bubbles when i shake it. Do you think it will still work?

[@growitbuildit]

It might work - time will tell. Let me know how it goes. But once the bubbles die down, as long as the soil looks properly stratified, it is probably ok.

[@codallthetime7045]

@@growitbuildit hey, it works! but the bubbles still present, thanks.

[@trishap2815]

How does top dressing help clay/compacted soil underneath??

[@growitbuildit]

The organic matter trickles down naturally and from worms moving it. And as it decomposes it turns into a glue-like substance that bonds small soil particles together, which are called peds. These peds clump up by themselves, but separate from each other forming pathways for water to infiltrate as well as plant roots.

[@shannongood8598]

Another question: After measuring the silt layer, what about adding a big pinch of aluminum sulfate (alum) to the sample water as a flocculant to settle out the clay? This is how I settle out solids in muddy water before filtering it when hiking in desert river canyons. In a few hours, the water is clear. I'm not certain how this would react to the chemicals already introduced in the dishwashing detergent.

[@growitbuildit]

I really can't comment as to if that would be a good idea or not. I know that you can get great results just using the powdered dish detergent, as that helps separate the particles well. Perhaps you could do two samples, trying one with using the aluminum sulfate after the silt has settled out. That would make for a very interesting experiment. If the results from both jars were the same, then you would have a quicker way to perform this test.

[@abilitylemur112]

Great video. Very informative. Thanks man.

[@growitbuildit]

[@wyominghome4857]

My new property next to the Wind River is silty loam. It drains well, but it's dry from years of neglect and the low rainfall in this area (11 inches). In my test flower beds I've noticed that simply adding sufficient water is enough to bring back lots of earthworms, but what can I add or plant to improve the soil's ability to retain water?

[@growitbuildit]

Hi - my best advice for getting the soil to hold more water is to add as much organic matter as you can get your hands on. I would make as much compost as possible, mulch, everything. I have no idea what your situation is in Wyoming, but I would be scrounging for everything I could get.

[@-sol-8350]

Did you mean subtract and not divide when you were calculating the clay?

[@growitbuildit]

Ho Sol- yes, you are correct. I misspoke at that spot in the video. In summary you just need to divide the layer thickness by the overall sample thickness, or height.

[@-sol-8350]

@@growitbuildit Ok I got it.

[@shafasha5461]

Thanks for the video. I have two questions, I did the test and then wait for it to settle (60 seconds for sand, 2 hours for silt, and 48 hours for clay). But the mark i did in 60 seconds and 2 hours became invalid as the line of silt layer descended downwards after i leave it for 2 days. Even the 2 days clay layer is settled under the first silt layer. Should i follow the first mark or remark them with the newest layer line? Second question, I've seen different time requirements for this method. Its 60 seconds for sand, 1 hour for silt, and 24 hour for clay. May i know why its different?

[@growitbuildit]

Hi Shafa, I would use the first lines you marked. Some silt or clay may settle in other layers if the others are a bit coarse. In regards to different times, I can't answer specifically why it is different. But the the seemingly large differences probably don't result in huge differences in results.

[@sheilaquattrocchi9274]

Great video!! Thank you so much! I have a test in progress now. My question, however, is that after marking the first "sand line", I marked the silt line at the two-hour mark. However, 4 hours after that, the solution has settled more and the silt has now settled almost a 1/4" more. Sooooo, do I re-mark the silt line or go with the original line at the two-hour mark?

[@growitbuildit]

Hi Sheila - I would just let the test run out marking as needed. But if the final levels are different then the initial marks, I would probably use the final level. Or, calculate it both ways if you got the marks. I bet you get the same/similar result.

[@sheilaquattrocchi9274]

@@growitbuildit Thanks so much for your reply. I think I'm going to go with the final results (3 days in) as the silt and clay levels appear to be very clearly defined now - and the silt level is notably much lower than the line I drew for it at the two-hour mark. Again, I sincerely appreciate your taking the time to reply. Sorry for my delayed reply, but I have been out of town with no Internet access - if you can imagine that! Ha! Ha! I am awaiting a fairly thorough soil test from VA Tech that I should have this next week. Am anxious to see what it reveals.

[@1star_god]

Im confused as to how adding compost could both create more drainage and halt drainage... is it based on where u put it? Or maybe how u apply it?

[@growitbuildit]

Hi - the organic matter will help break up compacted and clay soil, improving drainage. The worms help facilitate this as well. When it comes to sandy soil, the compost can hold moisture pretty well, so that helps improve water retention. It's a win/win.

[@xiongjun6743]

I did this test, I filled the jar about 1/4 at the bottom, added in detergent, shaked it for 15 min, and after 4 days, the clay layer is settled but the mark is about 2/3 from the bottom of the jar. And I know the water absortion is much higher in caly than sand and silt because of its large specific surface area. I am now questioning the validity of the % calculation used in this method because much of the thickness is increased due to water absorption. I wonder if there should be a correction factor for sand, silt and clay?

[@growitbuildit]

The fill went from 25% to 66%? That seems odd. What were your raw results? Also, was your sand component very coarse?

Happy new year from Greece! I want to make fire bricks sir. I have to use all of them? (Sand, clay, silt )

[@growitbuildit]

Hi - and happy new year to you. I'm sorry, but I have no expertise in making bricks. This test just tells you what your soil composition is. I suppose if you had a bucket with a spigot at the bottom, you could shovel your soil into it, and then just drain the spigot into another container with a cheese cloth after sixty seconds. This should leave the sand and silt in the first bucket, but allow the water/clay mixture to go to a cheese cloth.

how soil texture affects the relation between the soil water content and suanetion or tensin,by supporting graphicaly with intepration

[@growitbuildit]

Hi Worku - this illustrates the relationship well. It basically shows that sandy soils hold less water than loam. And that loam holds less water than clay. kbsgk12project.kbs.msu.edu/wp-content/uploads/2011/09/Soil-and-Water-Relationships.pdf

Or should I just add cow manure, worm castings etc...

You could add some clay, b7t it will take a lot to move it into a sandy loam. My biggest recommendation would be as much compost as you can make, and add it.

[@Jaredkprimalhealth]

@@growitbuildit Yea that makes sense. Do you know where to find clay to buy? I think I will add just a little bit over time/ on the top layer. With the compost

[@theurzamachine]

I thought I had heavy clay soil until I did this test and found that I have 50% sand, 35% silt and 15% clay. My question is: what is the ideal ratio of organic to inorganic material in good soil?

[@growitbuildit]

Hi Philip - I don't think I can answer that question. I have no way to actually measure it, as you need access to an autoclave or some sort of really hot oven. You get a sample, weigh it dry, then cook it to something like 400F. The organic matter burns off, and then weigh it again. But the short answer to your question, what I do - is add as much organic matter (compost, leaf mulch) as I can. I don't worry about ratios.
