The first 200 words of this essay...

Advantages

* Chemical fertilizer can be made much faster unlike the natural fertilizer

* It has much more NPK, usually around 20 to 60 percent, natural fertilizer usually only has a max. of about 14 percent

* If it is made according to the soil that it will be used on, it will do nothing but grow a healthy plant

Disadvantages

* Puts acid in the soil

* Strengthens pesticides(they become stronger and more resistant to chemicals that should keep them away)

* Other than NPK it contains inert filler and maybe some unnecessary chemicals

* It has very little carbon which is a key element in plants

* It has no energy, so it can only help the plant when there is enough organic matter around from where it can get the energy, otherwise it burns the roots and destroys the plant

* Chemical fertilizer also get a lot of water out of the soil which it contaminated and therefore pollute water

* It degrades ecosystems

* It releases a green house gas called nitrous oxide

So in total, chemical fertilizer is worse than natural fertilizer
