Slownickel has said you can manipulate that ratio for different ends. When the plant takes up nitrate, it takes up two more Ca ions than it does with ammonia, so during veg you can push Ca by using a 2:1 no3:nh4 ratio. But when roots take up no3 ions they exchange them for hydroxyl ions which will raise soil pH. So if your soil is alkaline then the ratio should be lower. Then during flower you can move the ratio to like 0.8:1 or something, so you get less Ca and more K.

interesting thx both of you

this yr ima go soft rock to take care of the P, no mg add and ksil to get k up.

Is that choice based on it's low carbonate content? Is it because your soil is built already and does not need a large amount of readily available P?

Soft rock seems like poor value at retail level, though I'm sure that by -the-ton it's cheap AF. I always got the impression that it's a very slow release too. Was it you that "makes soil that eats rocks"?
That would do it.

i need ca and p. aeems cheap to me

edit...albrecht...available but not soluble. this is the heart of his philosophy

 

[HillMizer]

That's cheaper than I thought. Yeah I bet a tote is cheap.
I'm just used to using an amendment that has 18% P and 22% Ca.It does cost more
Keep rocking, just curious. Thanks for sharing!

I'm gonna try and take a different route for P and use guano. Expensive but has some other goodies in it

has a burn time of 30-45 days. SRP is a better long term source, imo

You will get a little extra something with guano. Guanos also always test really high for heavy metals, especially lead. Bats are bioaccumilators because they eat mosquitos and we tend to poison the hell out of mosquitos anywhere near where humans live. I am thinking Cal-Phos this year also but at only 0-3-0 it is much less economical as super triple or even most bone meals.

Just amend with bats like sluicebox. Whole bats.

it is 20% p2o5 and ca with some silica. the 3% is immediately available while the rest requires microbe activity

mkp would work in this situation also but i love me some ksil anymore. it was part of a succesful stop pm program with nutrition only in a place that used tons of that zerotol shit

 

[plantingplants]

What was it about the k sil that helped control pm? I initially figured it was the Si but I have read about trials using MKP to control pm.. so maybe it's both K and Si? But I thought too much K will encourage PM?

 

[reppin2c]

I was reading that the addition of humates keep SRP from converting to being tied up with Ca and Fe. In a higher iron area like CO that could be a meal ticket

pretty good read http://blog.nutri-tech.com.au/the-phosphate-equation/

i tried spraying both mkp and ksil on active infections. neither did shit.

and yes too much k vs ca definitely feeds pm. i go ppm ca = ppm k with salts in coco. combined with other stuff that gets the job done. 0.5 to 0.7 ksil per gallon beats the shit out the equivalent k ppm fromm k2so4

all of my n comes from cano3

anyways...i hate coco

dont know whether to say baby steps in the right direction or you fuckin assholes, get a scale

Does anybody have any experience with sagebrush removal and allelopathic residuals? Last time I broke new ground there wasn't much sagebrush and I was able to keep plants 10 plus feet away from it. I really want to take advantage of what the clay has to offer but curious how long that runs its course.

EDIT fuck the new soil I got is from a gamble oak stand and oaks also release toxins. Im gonna go grab some and trans into it to see if Im fucked

 

[plantingplants]

Yea i'm wondering the same with a yard of mix I'm making-- i ended up with a lot of oak leaves in there- are they allelopathic? I'm gonna find out.

 

[reppin2c]

PP-you and i might bet the only ones who care lol

found this https://archive.org/stream/CAT92273488/CAT92273488_djvu.txt

Havent found anything yet about established plants having trouble yet or a time frame. Got a plant in the soil with a control. Gonna do a seed germ test with a control tomorrow. My only concern is trying not to overwater.

Theres gotta be some sort of test that can be done for concentration....

 

[orechron]

I would care more if I had contaminated soil. Now days theres an ELIZA test for most large bio compounds like proteins and carbs, but they are expensive (like $400) for one test plate) and the machine that reads them is even pricier. Sometimes bio departments at universities will read them for free. You're better off just doing germination testing.

 

[reppin2c]

What's you guys opinions on how many lbs of amendments it would take to fill peat with ferts to achieve a 1.0 ec. Im thinking it's around 4lbs but I could be way off

Also dont tell me half a ton of gypsum lmao

on a side not the cut i transplanted into that oak soil is doing good. Has a light tint and waxy.

 

[plantingplants]

Peat cec runs a wide gamut apparently. I posted it somewhere. 60-120 i think. Seems easy to test with a scale and an ec meter. for your particular current supply of peat anyway.
