What should be added to increase efficiency of bio-fertilizer, promote plant growth, sustaining agriculture and maintaining agricultural ecosystems?
Humic acids, strongly associated with humus, are one of the most effective promoters of nutrient absorption by the roots of terrestrial plants and cells of aquatic plants and algae during cultivation. There is quite a lot of scientific literature, including commercial advertising, which describes the powerful stimulating and positive role of natural humic acid solutions (trademark "Gumin" and the like) on the growth and development, productivity of agricultural plants.
Right now, we work hard to turn atmosphere into fertilizer, into crops, and then into sewage. We then treat the sewage to make atmosphere again. In my mind, the most effective way of maintaining agricultural ecosystems is to find a way to close the nutrient cycle, by using land-application of composted sewage.
That requires removing industrial pollutants out of the sewage stream, but that likely has to happen anyway.
So, to answer your question, we should add closed-loop nutrient cycles.
Green Revolution initiatives were not focused on an agriculture system but rather on a short term focus on monocultural results emphasizing agricultural inputs as the keys for increase crop yield.
Some of the background is that input interests were important as the impetus fr this approach.
While improved varieties were stressed these were designed to use more fertilizer and requirement more seed and need more crop protection.
In grain crops the biggest input is nitrogen fertiizer. Ironically 80% of our atmosphere is nitrogen.
A true green revolution focuses on one particular crop but the agricultural system.
Focuses on ways to avoid agrichemicals which compromise the environment
Focuses not on the chemistry but on the biology.
The way to do this is through better living through biology and eschewing chemical dependency.
Legumes in the crop rotation and use of mixed farming with returning manures and focusing on long term soil improvement which can not only address issues with inputs reduce costs but counteract greenhouse gases.
