My package of dolomite lime gives me measurements of lime for soil in terms of sq foot of soil…. WTF
Depending on how I choose to slice a gallon container of soil that could be 2 sq feet or 10 sq feet or a million sq feet. How do those people expect me to convert from 2 to 3 dimensions?
Since i have no idea i just over saturated water with lime and painstakingly added the water to the soil and measured the runoff a little bit at a time. Took about 2/3 a cup of lime and 25 gallons of water to raise the ph of the runoff from 5.5 to 6.3.
But… when i measure the runoff and remove my ph meter it goes up by .2 every time. And I don't know why. I also noticed that when i stick my ph pen directly into the soil its always about .2-.3 more basic.
Since hydroponics are supposed to be at about 5.5 i'm wondering if that means runoff should be at 5.5? Should i be measuring the soupy soil water or the runoff?
Also, i was wondering what I can do with the runoff water. Isn't that stuff basically fertilizer or a sort of compost tea? Can i save it in a jar and use it later? If so how long can it sit before some kind of killer bacteria grows ?
