This thread is for declaring (and experimenting with) foliar spray application rates of fertilizer, minerals, and such, since they can be pretty hard to find or convert, sometimes. Sources for information are below. Feel free to reply with more information, if you know it! My pump sprayer is 51oz (although it's advertised as 48oz, though it has a marker at the 48 point); so, I'll try to give rates for the standard gallon of water, as well as for 51oz (fluid ounces) of water. If percentages are given, there's a conversion guide below.
