I also used to worry that many people were not using NF techniques--not just for the sake of the land, but for their own loss of efficiency. Yet, as you point out, you cannot force anyone (nor should!) to do something. Instead, draw solace from the fact that it is a one-straw revolution! One farmer who begins this will have enough equity to prosper, and expand their farm. Competition and threats of bankruptcy or loss of market share are great arguments to change a way of life. NF allows greater productivity at less cost to produce a higher quality product. Market evolution ( woudl witness more and more do-nothing farmers in years to come under purely capitalist circumstances--with discontinued government subsidization of chemical and mechanical farming.
Even still, my farm is expanding well enough that landowners are taking notice that less is better. And I am sure that the other farmers who correspond with this group will admit that their neighbors are witnessing a triumph of a revolutionary technique. Even with negative subsidization, I am optimistic.
