We are not sure of your question. We do not have research on fertilizing with weed types.
You did not mention what you are fertilizing, trees, shrubs, vegetables, lawns, etc. Test your soil for pH and nutrient deficiencies first. It is possible you do not need fertilization. http://extension.umd.edu/hgic/soils/soil-testing
If you are fertilizing vegetables, then your need for fertilizers will decrease in time if you add some organic matter each year like compost, well rotted manure, or leaf mold.
