Bulk density lower for which soil
जबरदस्त पढाते है सर आप बस एक विनती है मेरी व्हिडिओ मे सबटायटल निकाल देवे बोर्डपे लिखा दिख नाही पाता.
बिग थँक्यू फॉर your efforts .❤
माफी चाहूंगा दोस्त
मैं Subtitles नहीं add कर पाता हूं
क्योंकि उसमे बहुत समय जाता है।
पर कोशिश करूंगा वीडियो क्वालिटी और बेहतर हो सके जिससे आप ठीक से समझ पाएं।
आपके feedback के लिए शुक्रिया ❤️👍
Sir, I have a question, that why we need to oven dry the soil for bulk density if we need to measure pore space as well?
Don't it exclude the pore space if we oven dry the soil?
Drying does not affect the number of pores in the soil. It only removes the water content.
We oven dry the soil to remove the weight of water from the soil.
So after drying If there are only soil solid particles so the remaining volume will be only pore space.
Sir please tell the name of book
I'm trying to focus on your lecture but everytime your smile distract me 🥲
Haha keep trying 😂❤️
Keep learning ❣️
@@agriculturalstudies 🥲🙂
Mera end exam bhi h
8 may se ,to please book ka naam bataiy please sir ,jo professor padhate h vo samaj me nahi aata
For semester exams you should go with the class notes provided by teachers.
For competitive exams like JRF Best book is ISSS.
If you can't find ISSS then read the D.K. Das.
Wohoooooo,once again ❤❤
Hehe hn mere bhai 🫂💕
Sir how puddling increases bulk density?
As we know Puddling is a process that involves repeated tillage under ponded water. And as the land get more soft and loose I think the volume of the soil increases and so the bulk density should be decreased.
But if you have read that in any authentic book then please tell the name of the book.
Infiltration rate of rain water is high in which soil and why?
I think the Infiltration rate is high in the sandy soils because of the presence of more pore / air space.
When soil porosity increase what happens to particle size?
Soil size par porosity ka effect nhi aaega.
Yani density kam jyda hone se soil particle ka size nhi badalega.
Par Soil size se soil porosity change hogi.
Yani soil particle Chhota hoga to so
No of Pore space jyda honge
To us se volume jyada hoga
To us se density kam hogi.
Vo bhi bulk density kam hogi.
Par particle density par farak nhi padega .
Bro English subtitles please 🥲
I really tried to provide subtitles
But it's actually not working
I need a separate guy to edit and ready subtitles..
But I'll try again and soon I'll provide subtitles properly.
