Dear viewer/subscriber, if my videos helped you a lot (maybe you aced your exams as a student, or you won the admiration and full attention of your students as a teacher, or you got your techniques right as a hobbyist), then its my humble request if you could take a moment to consider supporting me on anyone of the following platforms:
Patreon : / membership
KZfaq channel membership: / @thesingtangpascienceguy
Patreon members and channel members will get exclusive access to members-only perks and added benefits such as free PDF notes, Q&A doubt clearing chat sessions, Experiment video requests, Member shoutouts, Behind the scenes and more.
Or if a monthly payment is not convenient for you right now, you may instead consider supporting me with a one-time thankyou gesture by clicking on the SuperThanks Icon below my videos next to the like dislike buttons. Pay the one-time-only amount that you feel is worth the help and benefit you got from my video.
Apart from Subscribing to my channel and sharing it with friends, colleagues and students, you valuable one-time or monthly financial support will really help sustain this channel and make it possible to come up with even more engaging and educational content.
Creating experiment videos involve hundreds and thousands of dollars put into procuring the requisite chemicals, equipments and labware to make a single video. To say that i will be extremely grateful for your support would be an understatement.

I would suggest covering the soil surface with the Parafilm during the leaching period. Otherwise, the evaporation of the surface soil layer will cause a large error in the later WHC calculation.

What is the ASTM standard followed for performing this experiment?

I searched this up because I was wondering is soil's moisture content can be greater than the soil's own mass like 180 % or something like that... Can you solve my doubt?

Hello Thomas, thank you for the demonstration, is WHC the same as field capacity ? if yes, what's a 100% Field capacity, and how do we measure it ?

Please tell me the average water holding capacity of black soil having clay % b/w 60-70

Hello Thomas, i wonder why you used 25 gram soil to measure the WHC? I mean why 25 gram or is it necessary to use at least 25 gram soil when determining the WHC?

I have one question In the first method , at the time of using formula the upper thing is in volume (ml) and lower is in( g) How can you take in % ?

@abda9212 5 ай бұрын

Good experiments but I see two problems. First different soils have different weight densities, that's why they should be measured to equal volume not weight. Second the random method of pouring the water in the first experiment can introduce inaccurate results. For example, at the first round you poured an excessive amount in the second sample. This caused excessive run off.

Hello Thomas, I am doing an experiment with plants that requires me to water plants to a 60% saturation level. Do you know how I should do that from having the knowledge on what the soil's water holding capacity is?
