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.
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 ?
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?
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.
