Microscopic level of Biology in soil and solution

Hi,

hope you doing well,

I just bought a microscope , and I’m enjoying wonders of microscopic level of life inside the soil and solutions .

the problem I’ve got is I cant  find good reference to recognize what I’m seeing in microscopic level

I mean I cant recognize what bacteria or protozoa ETC good or bad I have in my soil ,solution and fertilizer

kindly let me know if there is a good reference of names and shapes and ETC of bacteria , fungi , protozoa ,
