To Study The Texture of Soil Samples 12th bio. Practical no.15

- Опубликовано: 16 сен 2024
- Procedure
Three methods are suggested here. Any one of these may be followed.
Method I
(i) Collect about 300-500g of soil from two different locations. Label them as sample A and B.
(ii) Dry the samples in an oven, or stove or in sun to remove the soil moisture (capillary and
bound water).
(iii) Select the 3 sieves of different mesh sizes (2mm, 0.05mm and 0.002mm). Arrange them in
a collecting chamber as shown in Fig. 15.2.
(iv) Place 200g of the soil in the Ist sieve (sieve of 2mm mesh) and close the lid. To sieve the soil,
shake the set manually for 5-10 minutes and collect the three soil fractions.
(v) Weigh the soil fractions viz-sand, silt and clay
collected in the 3 compartments
Wt of soil sample taken - .........g
Wt of sand fraction - .........g
Wt of silt fraction - .........g
Wt of clay fraction - .........g
The weight of three fractions should be equal to the
total weight of sample taken for analysis.
Calculate the percentages of the various soil fractions
and tabulate:
Calculate the percentages of sand, silt and clay
fractions.
Use the textural triangle now. Note that the three
sides of the textural triangle represent 0 to 100% of sand,
silt and clay respectively. Note that (i) the percentage
lines for clay run paralled to the base line of sand
the precentage lines of silt run parallel to the clay side of the triangle and, (iii)
perentage lines of sand run parallel to the silt silde of the triangle. In reading
the textural triangle, any two particle fractions will locate the textural class at
the point where these two intersect.
Watching this practical out of the exam centre in last 15 minutes.. 😅. U are boon for us sir
How Was It? Was It Good ...
Btw Legend🤭😂
@@Pari-rs6lz oh yeh it was😅
Thanku so much ❤️ this will so helpful video to us 💖💖😊❤
There is.a correction in this video
you have to discard the rocks which were found first
and then consider all three soils beneath it and take their percentage

Apki itni Sari videos dekh li hai
Ap sapne mai bhi aa rhe ho 😆😆😆
Oooo...hoo...bohot hard😜
@@LetMeExplainnowbharatpanwar plz explain how to determine tree height and estimation of litter biomass ،water discharge of stream
Ye triangle k andar sare labelling krne honge ?
Mtlb ye triangle banake sirf loam hii mention Krna hogaa or kuch nhi
Apko ye triangle ki Xerox milegi exam me ager ye practical ayega .. apko sirf line khich ke identify karna he
thanku sir
Tq sir for it
Thank u so much for sir❤️👍
Kdk awesome
It was helpful thank you
Tyssssm....very helpfull
Sir ye triangle pracrical me milega
❤
Help full this video
Tx sir
Thankyou so much sir
Comprehending work
Sir collecting chamber wale component ko calculation mein include nahi karna kya?
No
Nice great doing
Sir, best
Thank you!
Sir
Ye jo graph vala portion pen ya pencil dono me se kisse krna chahiye exam me?
Exam me pen se ..
@@LetMeExplainnowbharatpanwar thank you sir 19 ko mera board practical exam hai 😢
All the best... mere अवेंजर...तूफान मचा के ana..
@@LetMeExplainnowbharatpanwar 🔥
Sir matlab jis triangle mein 2 intersect hoga line mein wahi texture hoga soil ka
Yes
Thank sir
Sir the soil triangle will be provided during the exam or shall i learn it?
Did you get the answer??
@@lifegoeson_101 you'll get it i've given my practical test and it was provided by the invigilator.
School will provide you
Thank you ☺
Sir ye last vala triangle denge yaa yaad krna hoga ??
Jordar
Sir soil texture triangle board k practical me yaad karke jana hai???
Please jaldi reply kijiyega sir
Abhi 2 hrs me mera practical hai😱😨😭😓
Sir please reply 😭😓
As weight of three fraction be equal to to total weight of sample taken
Yep... Ya
No bro.. SOME AMOUNT OF SAND WAS ALSO COLLECTED IN COLLECTING CHAMBER.. WHOSE WEIGHT IS NOT COUBTED.. understood?
Yes.. But kuch soil Sabse niche bhi to collect hoti he dear.
👍nice...
Tanks
wow sir
By good work
Nice video
Amazing
Thanks bro
👍👍👍thank u
Only 4:30 hrs left for practical and I almost complete my all practical
Thanks
Sir iske 3 method hai sare bata dijiye
Sure. But ye main tha to pehle bta diya bad me vo bhi Ho jayega
This sir voice match nalin Khandelwal.
Exam mai texture pata karneke liye chart milega kya?
Kya sir ap n sab practical dale hei 12th k?
Yes..chack in playlist
@@LetMeExplainnowbharatpanwar thank u so much sir ❤❤❤such a great effort 🥰😊😊😊
