Organic fertilizers are what I use but then again I was hesitant on replying since I sell it. Yes I believe it is for a benefit of the land and the limitations it has are also present in any products used. I like organic since I eat organic.
Now there is also other solutions as well. One would be the introduction of the tea. This is the castings NOT the compost and best done with distilled water through it and blended and aerated and after mixed used in 24-48 hours. As it is the microbial activity not just the chemicals from castings that make the difference. this introduction of the micro organisms are the bottom of the food chain where worms will dwell and feed on bringing more nutrients and expelling a balance. Then there are spiders, insects to consider as well for the contribution for the soil since manures have different make ups and the animals and insects have different relations to different plants.
This is a loaded question and needs analysis on individual basis for a true answer of what is best for your soil from geographics, temperatures, environmental aspects now, insects and habitation, usage, and the pH level and best suited pH level for growth plants. So in simple terms it is best to see the pH of your land first, pick your desired crop and check on yields averaging in geographic for feasibility and move from there one step at a time. Dirt is no longer just Dirt
