Chemical Fertilizer vs Organic Fertilizer comparison. A chemical fertilizer is defined as any inorganic material of wholly or partially synthetic origin that is added to soil to sustain plant growth. Organic fertilizers are substances that are derived from the remains or byproducts of natural...

So I took a quick look at this, its not what I would call a reliable piece of information. Their idea of what a "chemical" fertilizer is inaccurate. First calling anything a chemical fertilizer is stupid, everything is made up of chemicals, including organic materials. What we are really comparing in this industry is mineral nutrients and organic nutrients. Then there is the argument of what definition of organic are we talking about, agricultural organic or chemistry organic; if we use the term organic in chemistry it means anything based on carbon chains, which can still be found in mineral nutrients. The source of the material is wholly irrelevant when talking about mineral nutrients, take
Botanicare for example; if you read their labels a considerable amount of their source materials are what would appear to be organic so why are their products not considered organic? Because they process those organic inputs into refined forms where only the clean necessary elements and chemicals are left.
Organic nutrients do none of the processing, they are relying on the time after they have been applied to break down. This process does also require good living micro-biomes in our medium to break down those organic inputs into forms that our plants can take up.
I personally have been an organic grower for many years, though some of the living soil guys may not agree with me. I have found that a lot of the varieties I grow do taste better than the same plants grown out by other people who use mineral nutrients. But this may simply be because they didn't encourage a good micro-biome to exist around their plants roots. I also do believe organic gardening is better for the planet long term, but not because it grows better plants. To me I would rather have organic materials getting back into our ground and water as they are less processed and will typically accumulate less of any individual chemical. I also think theat organic gardeners make an attempt to be less wasteful with what they are putting into the plants and often have more eco-friendly practicies that keep the land they are working in top quality (actions like crop rotations versus mono-cropping). But anything in excess, even organics, will be a detriment to our environment and to us. Just because something is organic does not mean it is by default safe. There are plenty of organic poisons out there, many of which come from plants, that will do major harm to you or I. So organic as a term that is slapped onto our food or nutrients is not what makes organic gardening better.
I am also in no way opposed to using mineral nutrients, I am currently doing a test run of a new mineral nutrient line. It actually includes 4 species of Bacillus right in their bottles, so clearly the mineral nutrients I am applying aren't going to kill my micro-biome. I am very much looking forward to see what this line can do, so far my plants are looking beautiful. In fact I have a side by side going, I am doing 1 large Black Lime in organic soil and I will have a few smaller cuts of the Black Lime going in coco with the mineral nutrients. So I will have a true side by side. I honestly am expecting minimal differences in the two results.
So what I was really getting at is I completely disagree with the OP and both organic and mineral are good options for nutrients. But sourcing and use does matter. I just had to get into semantics. Why? Because that is who I am. Sorry for the long post to say so little.
