found a bag of selenium premix at another feed store today and bought a bag to mix with salt...
how much of this i would add to 50lb of trace mineral to bring the selenium up to around 75-100 ppm?
tag on my bag says 35.50-37% calcium and 600 ppm selenium instead of what the site has listed
To answer your question:
adding 1 lb of .06% selenium (600 ppm) to 50 lb bag = 51 lb bag and 32.7 ppm
2 lbs = 52 lb bag and 65.4
3 lbs = 53 lb bag with 98.1 ppm
Mixing it evenly is easier on paper than in real life and then consumption of carrier used is even trickier.
Are you planning to mix it with 50 bag of salt? or 50 lb bag of trace mineral?
You seem to use both terms (salt and trace mineral) as if interchangeable.
IF using trace mineral as the carrier.... how much selenium is already contained in it?
I'd say you'd be better off buying the mineral with 30 ppm and trace mineral salt either Selenium '90' or '120'.
Selenium '120' trace mineral salt adds 54 ppm selenium
'90' trace mineral salt 40 ppm
combined with the mineral = 84 or 70
