Nutrition experts, your help needed please!

OK, been researching loads but can't seem to find a clear answer;

I can't get my forage tested as the fields have differing soils & forage, and hay comes from various places.

Can anyone tell me please the maintenance levels of Biotin, Riboflavin, Cu, Zn, Cr, and the ratios of Ca/P/Mg needed for all seasons?

Thank you

Thank you - I've looked at the site before but (going to sound thick here) can't make head nor tail of it! :/

Try feed xl (google) its really simple but you do have to subscribe to it.
