Soil Sampling, Bulk Density, and Water Content
In this video we demonstrate a technique for collecting a soil core sample and measuring bulk density and water content in the lab.

In this lab we demonstrate how to measure soil temperature with thermocouples using a datalogger.
Permanent wilting point lab: SWC Part 2
มุมมอง 10K12 ปีที่แล้ว
In this video we demonstrate a technique to measure the water content of a soil at permanent wilting point (15 bar or 1.5 MPa). The 1.5 MPa measurement is the last point needed to construct the soil water characteristic curve in Lab 2.

What is the ASTM standard followed in this experiment?
What is a name of this equipment?
Oven dry at 105°C for 24 hours, whoever wondering.
thanks for making this video 👍🙏
Good 👍
mam i like your work .i am interesting in swcc .kindly send me speared sheat in excel formate for calculation .i shall be very thank ful to you
Nice explanation
Hello! Great video. At what temperature should we bake the sample for 24 hours?
Usually oven dry at 105°C
what a dumb , useless experiment
Thanks for this. If my professor ever covered this in class, I never heard it. Saved my butt on this phys hydro problem
Hello ma'am please help me in that...
I am Post graduate in Horticulture from india can anyone tell how to apply job
Soil babe
What temperature was oven at?
im in love
damn sexy
What is "topps equation"?
Beautiful legs though 👅
NICE
Hi! I am Rwandan.I would like to ask how you can make moisture characteristic curve when you have soil moisture content in percentage and matrix potential in bar.
Where is the rest? this is just legs show
beautiful sampler with pretty legs
Hello, I'm from Japan and study geotechnical engineering. Btw I focus on unsaturated soil and especially infiltration. I try to develop a laboratory method which is steady and direct measurement method to measure unsaturated hydraulic conductivity . Well, my question is what is the problems of Van Genuchten model or the other kind of prediction model? I'm wondering that my research would supposed to be more advantage than some prediction models. Please give me your advices. The best regard from Japan
You might want to check out HYPROP and email the developers with this particular question. Regards, from Germany
Danke schoen Btw Ich bin Yuuk und i have studied in TU Dresden 5years ago. What is your name?
Hi thanks for useful videos. I'm irrigation student and I'd like to know that how could I have access to the documents related to these videos.
which soil sampling equipment and tools are appropriate for disturbed and undisturbed soil sampling?
Hi, Great video Could you be able to confirm if you do follow ASTM D6836? Thanks
Way to go..! Beautiful sample, Katie... ;)
Hello, My name is Dereje, I'm frome Ethiopia. how much the standard volume of core sampler, please tell me by using my Email addres
Thank you so much Dr.
Lady, your core ring sampling for bulk density is NOT correct. You shake the soil too much and the bulk density will be disturbed and NOT accurate anymore. You should place another ring on top of the first ring and knock gently to ensure the first ring completely buried deep before taking the ring out again. Again KNOCK the wood gently not too hard like what you are doing.
That's true. It's either that or, in peat soil, we usually just use knife and gently set in the core ring. It was incorrect how she hammer it in. It's no longer a sample fit for bulk density analysis cause technically, the pores has already been initially hammered.
Not correct
Not correct because the lady is compacting soil and the results will not be representative of natural / undisturbed soil. Not good at all!!!
nice video . please i need your email , i have some question
Use EPPs
what did u used for tdr measurement
she's hot.
Thank you very much! We don't have so clear videos to explain this test in portuguese! Thank you very much!

this video very good , please i interested for water mov. and i need connect with this Mis.
