Part 2 of dplyr introduces chaining (sometimes called piping). Chaining is a framework for R syntax that can take numerous complicated commands and break them down into simple sequential subunits. The end product is code that is easier to both read and write.

From where does the 12 comes from in the eq of 12(7-6.6) for finding exchangeable acidity?
Reta Drive
Very interesting video thank you

Best explain about CEC,that's why the potassium humate has a good function in soil
Well explained
you did a nice job, thank you, greetz from berlin
Thankyou Thankyou Thankyou so much, Ive been watching your playlist for weeks. Much love from Thailand.
Useful tq😊
What are the different types of beneficial microorganisms?
Helo! What are the different types of beneficial microbes in the soil and how it can affect the acidity and ph level of the soil?
Omg i hate it so much when People use the Word "OK?" all the Time, OK?
Oh my god I hate ppl like you that go out of their way to criticize without the intent of improvement. So learn with this one and try to be less miserable next time.
Micronutrients should be split into *transition elements* as they specifically enter into enzyme proteins and enhance enzymatic function.
Thank you for the fundamentals. Very useful to learn about average plant matter analysis: CO2, H2O 96% Ash cations 1.7% (K, Ca, Mg) Nitrogen 1.5%
Just now seeing this 4 years afterward. Havent seen your more recent research. But Good info. Thanks. If I might speculate: id say that while measuring CECs are informative, maximizing plant root exudates to build soil structure are 10X to 100X more important than balancing Ca:Mg ratios. And probably will reduce costs/acre as well.
If you have too much Mg wrt Ca in the soil it will be hard and tight and lack porosity. This will lead to a hostile environment for the biology that feed off of those exudates as the Oxygen is less available.
Nice lecture 👍
my meter is not calibrating correctly
बहुत बढ़िया जानकारी देते हैं।
Sir, I want to make 50 kg of SSP fertilizer, so can you tell me how many kg of sulfuric acid will be added in it. Sulfuric acid is 98%.
what an ignoramus - you are obviously not a grower.
Can someone please tell me " The relationship between PH and charges in the colloidal complex?
Lets invade Canada!!
The buffer pH is the pH measured in soil test by electrode?
What if it just keeps flashing the number and never gets the smiley face?
Thanks...
Covering hard flat surfaces with egg crate, moving blankets and/or sound damping panels would dramatically improve sound quality.
ohio 💀💀💀
I do soil testing if I have trouble with greening and keeping a thick lawn. I’ve been using Carbon G to raise the CEC’s. I first experimented with my own lawn. I must say, a very impressive product. Do you have any experience with this product as well ? What other great products are available to raise your CEC’s ?
Hi would I still need to put liquid fertilizer down in the row in corn if I put down 2 ton acre last year was beans in the fields let me know thanks
VERY NICE!!
I'm studying for the fundamentals exam. This video was very helpful as a refresher. Thank you.
Sir can I get these notes??
Please reply me
Around the 24:00 mark you talk about calcium displacing Al and H, thus helping to increase pH. My understanding is, though, pH is not affected when gypsum is the calcium source. Is it possible to expand on that please?
Did you get any explanation on that, because lime is the only one that can change the PH but gypsum it neutralizes, but I want an explain on how does it work without changing the PH
Nice 👍 Thanks for making this valuable information available
I am interested in the slides. Can you share those CEC graphics in high quality ?
Gud one
Thank you so much for uploading sir
L
…. I hate math
Thanks Dr. Please can you help with an example of liming solution use to obtain the buffer pH and what could be the ratio of mixture?
How did you get 12 for the exchangeable acidity?
Sir you explained very clearly.Thanks for uploading on you tube .
Hi. Thanks for your presentation but I didn't get what is the buffer solution? I really need the answer
Can someone post a link to the thesis in the description of the video once it's published? Thanks.
That messy data is the Billboard top 100 for the year 2000. It is a toy dataset in the tidyr package.
Great
Thanks doctor explained very well..Keep it up ..It help me lot .
Which one is more important cation exchange capacity or base saturation?
Compute the % base saturation of a soil with CEC of 100 me/100g and whose exchange sites are occupied by 20me/100g of basic cations? Pa answer naman po.Slamat.
