First, I'd suggest that you choose an expendable test subject; three different types would be even better. The thirteenth marigold that you don't know what to do with, the seventh tomato when you really only need six, a volunteer melon of unknown parentage, or even just a big broad-leaf weed that's easy to see and keep track of. Practice your test mixes on these plants first, and possibly at two or three times your planned frequency of use. You should know fairly quickly if a particular mix is safe to use on the rest of your plants.
Fresh manure shouldn't be applied to fruits or leaves that are to be consumed of course, but if that's not an issue and you run low on aged compost you can make a "tea". I usually use about a quarts-worth of poultry droppings to four spades-full of horse (but you can use whatever is handy for you) and dump it in the largest tub you can find -say 20+ gallons or larger, then fill with water. Cover with tulle or fine screen to keep the bugs out and let it sit and age for a week or two (or longer if you have the time). A daily stirring might also help to speed things up a bit and may even sweeten it faster, but I rarely remember to do it.
As you use your solution you can refill the tub with water repeatedly, as needed, until it starts to clear or look a bit thin. Then just add materials to start it all over again.
