He took 2 wks for mine in April but I figured there was a spring time rush. I added his recommendations and the garden looks great.
Albrecht, Tiedjens and Reams as well as many others realized that the "balancing equations" exist and I believe are still far from perfected. Each crop in each soil requires the correct proportions of elements to come closer to reaching its' genetic potential.
Within these distinguished group the general conversation was between what proportion of calcium to that of potassium (K), magnesium (Mg), sodium (Na) and hydrogen (H). Those that reached the highest levels of calcium in proportion to the other bases in the base distribution, were Tiedjens and Reams, both aimed at 85% Ca. Interestingly enough, Albrecht late in his career acknowledged that his was indeed where Ca needed to be brought to reach maximum yields.
Whenever I get Calcium too high in my soils I run into Potassium deficiencies. This has happened with Ca between 70-75% saturation and K between 2-4% saturation. 5-6% is what I shoot for now with cannabis.
While these US authors took years to figure this out, you could have asked nearly any Italian or French grape grower to answer that question and they would have said that the only way to get to quality, is having more than 90% Ca. Some of the best grapes in the world come from 93-95% Ca soils.
This surprises me, especially due to the fact that grapes need K to fill all that fruit. In a 95% Ca soil where would Mg and K %'s be? 3% and 1%, leaving 1% for micros? That seems remarkable.
Another clear example is the Iron/Manganese relationship. Most investigative work demonstrated that when this relationship is less than one (more Manganese that Iron in the soil) that yields often double or even triple, which is the case for pineapple being grown in Hawaii versus Central America or Mexico. Rice is another example as well. Loves more Manganese than Iron in the soil.
I've never seen a test with Mn higher than Fe, but I'm in the process of testing high Mn soil with canna and veggies.
Many crops, blueberries being another, are manganese accumulators and have levels of Manganese upwards of 5 times that of Iron, and have amazing quality fruit and yields.
Good to know. I'm going to be investing a lot of time into blueberries in the future.
Yes, there exist balancing equations, but the dynamics of water and soil types and soil formations along with crop specific requirements makes for a lot of room for error. Thus the importance of testing in house.
The page won't let me post a bunch of files due to their size. If you PM me I can send you them in private.
You'll have to get to 50 posts in order to pm me, but feel free when you do.
The Italian article you will have to run the CEC distributions. If you can't run them let me know. The distributions were 84 to 92% calcium, I stand corrected. The comments that I made previously were quotes from a famous Italian consultant that I have had the privilege to work with. The article was one that I found on the net. Decent article.
I don't see any values for H+ in the data. Is it safe to assume none? I also can't find what analysis method was used for the soil?
I have a several blueberry articles as well that show how the blueberry is a Mn accumulator in soils that have a 1:1 Fe/Mn ratio.. Articles on rice and pineapple as well showing superior yields by far with inverted Fe/Mn relationship articles, too big to send.
I did add another great article where you can look at the high P and high Ca soils and then look at the THC levels that were achieved. It is important to run the base distributions to see the real story....
In my own experiments in rice hulls, applying micros at 1:3 Fe/Mn, blueberry (real blueberry) plants had flower and fruit long before the rest in all 5 varieties tested.
Did you apply manganese to your grow? With those iron levels, the response would be barbaric.
Hey slownickel, I'm just wondering what your real beef is with Astera? You've criticized him and his recommendations in several posts and left at least three one star reviews on Amazon under two different accounts and it actually looks like you left 4 one star reviews under three different accounts and yet, all the other reviews on Amazon rave about his book and on this forum I have not seen one person who has had anything bad to say that has used his recommendations and amazingly I haven't seen anybody's plants die of boron toxicity like you predicted would most likely happen.Those reports all seem to be from Logan labs. I have no personal experience with them, but a lot of friends of mine do. Their numbers are all over the place. Firstly, there is a huge human error digitizing the data constantly apparently.
Secondly, their P numbers always seem to be off dramatically.
Steve Solomon recently visited them on his recent visit back to the US and his comments were not too kind.
Most of us use Spectrum in Ohio. Super professional and they run the analysis that you request and in the manner that you want it done.
Using a good lab is critical. I know Astera insists on this lab and I see he is all over this site.
Another good friend that works at the Univ of Kentucky in their agronomic section also has not been very kind regarding this lab either.
With that said, your (iron+aluminum/manganese) ratio is barbaric.
Most folks don't worry about aluminum in neutral pH's. However, based of 30 years of soil and leaf analysis results, that is not a safe bet. In fact, aluminum toxicity in alkaline soils due to the influence of bicarbonates is more toxic that the forms of aluminum at acid pH.
Yeah, just realized that I had to get to 50 posts before I can PM anyone. Interesting rules.
Mn at the lab that I use in Ohio is indexed as is copper. These indexed numbers are dramatically lower than the real Mn and Cu numbers for two reasons. Ph and organic material.
How do you adjust your micronutrients if you aren't getting an idea of what the total is in the soil? I've used A&L Labs in the past but not Spectrum. In clay or native soils I'd like to know total pumps if most cation micros are being held by actual clay.
So if you are in one of those mixes that is pure organic material, Mn availability will be a problem. You are probably better off purchasing an Albion or Baicor amino acid chelate and use it instead of a sulfated form of Mn.
In my experience having Mn available or to even stay in the media has been a problem. I'm still trying to get to the point where I don't have to foliar so much.
I tried to reply to a post where someone showed their soil analysis and the number were insanely swayed towards iron. Unfortunately the comments go to the end. Not sure whose analysis it was. I will look to see yours if I can find it.
Those reports all seem to be from Logan labs. I have no personal experience with them, but a lot of friends of mine do. Their numbers are all over the place. Firstly, there is a huge human error digitizing the data constantly apparently.
The guy that runs the local A&L branch prefers not to use Mehlich 3 and claims it isn't as accurate as methods used by all the labs out east. It is extremely expensive however to get all the data I want from A&L, about 3 times more expensive than Logan's testing package. Some quick digging on the web shows some links that have Mehlich 3 giving comparable results to other tests. I'll post one of them at the end of this post.
Secondly, their P numbers always seem to be off dramatically.
I've found the tcec to vary quite a bit with my indoor soil, which I've had analyzed 8 times so far. The cations have been pretty consistent though, at least the ratios.

How does bicarbonate lead to aluminum toxicity?
