Here is a test from this year that is unfiltered. I did use a aquasanta water filter with carbon filter and uv light as I have high nitrates and coliform in my well.

That Mg in your water is not the issue.
Hit with a tiny bit of gypsum and then start top dressing and getting some K on....
I already topped with some gyp and some bio live. Then a feed with some amino's, kelp and a little sugar. I am going to baby the hell out of this crop,
Easy,
Your K is already too low. I imagine there is some K in the kelp....

My water supply looks like this, but i use
as much rain and r/o water as possible. Tap water would account for less than 50% of all
irrigation.
Component Value Unit pH 7.3
Total Dissolved Solids (TDS) Est 260 ppm Electrical Conductivity 0.43 mmho/cm Cations / Anions 4.3 / 4.2 me/L Sodium, Na 34 ppm Potassium, K 3 ppm Calcium, Ca 39 ppm Magnesium, Mg 10 ppm Total Hardness, CaCO3 139 ppm Nitrate, NO3-N 1.3 (SAFE) ppm Sulfate, SO4-S 8 ppm Chloride, Cl 73 ppm Carbonate, CO3 < 1.0 ppm Bicarbonate, HCO3 91 ppm Total Alkalinity, CaCO3 75 ppm Total Phosphorus, P 1.33 ppm Total Iron, Fe 0.03 ppm
Happy new Year

Sure looks like you got a bunch of gypsum in this sample...

Thanks for taking a look.
Certainly could be true. I irrigated 200gms of gypsum in 2 gals of r/o water through 20 gals of media about 3 weeks before sampling. About one week before sampling i irrigated it again with 10 gals of rain water. I took the samples from a few different spots in the bags, mixed them up and shook them through a coarse china cap. Since the soil is very recycled the sieving stopped more than ~70% of the sample material from passing through.

Slightly off topic, seeing in your SIG "one straw revolution" I read through the text. He's a Buddha!
But I wondered what you thought about his practices of relying on local amendments to maintain optimal conditions. Fukuoka doesn't seem concerned with or effected by trace element deficiency or base saturation.
Do you wonder if he might have done even better with a K3 and a prescription?
Never read his book, but I loved that quote.
There were a group of Shogo's from Japan that followed Fukuoka concepts in Costa Rica. They had the worst veggies you could ever imagine. I did get them to use some calcium carbonate one time, but they wouldn't let me help them with anything else. The project closed, the Japanese went home and the farmer went broke.
Even with bio-accumulator plants it would be impossible to grow much of anything at any scale.
The real queen of this topic is Elaine Ingram. The disasters she has made in so many farms is terrible. She makes folks believe that with enough biology you can make everything that you need available. Either she couldn't get folks to grow enough biology or she is wrong.
There are soils that have no boron. Or no manganese, or are toxic in iron and aluminum. Or have no phosphorus. None seem to have enough calcium. And for those growing cannabis, which is an annual, how do we magically reverse what didn't function in the ag universe and in 6 months?
Seems that everyone that has tried using a bit more GOOD science is liking the results!!!
But hey, maybe I am wrong.
How heavy is this mix? How long does it take to dry out?
Did you ask Spectrum to post the results to my account so that I can download your data in excel and at the same time get the indexed metals (Mn and Cu)?

This mix is pretty light, when plants are cranking it goes from saturated to slightly moist in 2 days, 3 days max @ 75°, 60% rh, ~1100ppfd..
Right now it's sitting in 15 gal smart pots in a dark, 50°room. It takes about 10-14 to go from saturated to just damp. It's not a tight or heavy mix at all.
Fukuoka uses rice straw to take care of business, and feces.
I did ask spectrum to post to your account. Test date is 12/26.
Not sure why, but it didn't get posted yet.
Your mix is too heavy. You really want a mix to dry out daily so that you can water and feed daily. Maybe you need some more rice straw.... haha

Thanks. I think maybe my analysis is skewed because of the sieving. The fines that filter through the mesh are maybe like 35% of the total matter.
Do you think there may be wisdom in drying a new sample, then grinding the materials and finally sieving the ground matter for analysis?
Alternatively would adding in rice hulls, scoria or something like perlite be useful?
Did you use Calphos and bone meal to build Ca and the resulting P? Were those micro #'s as anticipated?
Our samples test very similar from the looks of it. I am just a season behind... Is this your long dep bed that this sample was from?
