Weedy dry land pasture management ...
Delta County Colorado
I am not sure what article you are referring to, or what your question is. Could you explain a bit more?
Perhaps it does exist, but a document that would cover all of the topics you are after would need to be of book length, perhaps a set of books. A person able to answer all of these things accurately from memory might have a masters or PhD in agronomy and soil science , so years and years of classroom instruction, especially since what is a decent OM content or mineral content in one soil and situation is pitiful in another. Since extension tries to deliver information in a way that is easy to use for a landowner/manager the documents often cover the major issues and then if you want to learn more about specific components you would need to find another article on that topic.
For explanations of ranges of soil micro and macro nutrients the CSU soils lab has a good fact sheet: https://extension.colostate.edu/topic-areas/agriculture/soil-test-explanation-0-502/
When it comes to pasture or rangeland care, the amount of forage and the types of forage plants that can grow is often most limited by the type of soil (amendments can help but are generally not a long term solution) and the amount of rainfall (unless irrigation is available). So the praying is that the rain comes at a time the seeds can germinate and establish. There is no silver bullet plan that can 100% of the time bring a pasture back into production.
Also, the vast majority of land in Colorado is currently or has been overgrazed, many areas of Colorado cannot support even one animal unit on less than 40 acres, every time the ground is overused (grazing, trampling) it gets worse. Weeds are usually the first issue to address which is likely why the article you were looking at focused on weed control, once weeds are controlled covering the ground with a good plant is the next step before weeds get a chance to return.
If you are looking for Organic solutions to weeds you will need to specifically look for organic documents , some will include both methodologies but most are aimed at conventional management options, unless they are titled for organics.
You may also find the answers you are looking for in specific relation to your property by contacting your local NRCS (Natural Resource Conservation Services) office. They can help you determine the potential and abilities of the soil you are working with and what can be reasonably done to improve it.
