Organic fertilizers are made from naturally occurring substances, and include by-products or waste remains of the animals. Dead plants and dead animal remains are also often used as fertilizers in organic farming. They are naturally chemical-rich and contain high amounts of nitrogen, phosphorus and potassium (NPK).
The main difference between a chemical and an organic fertilizer is that the former come out of a lab and the organic one comes from living beings. A chemical fertilizer is synthetically prepared to include the vital nutrients that are necessary for the plant's growth process. All of them contain the normal NPK requirement and any other nutrients as required.
Comparing the Two Fertilizer Types
Benefits of Organic Fertilizers
They are made by natural processes. Although they take time to make due to the nature of its 'ingredients', they prove to be much better when you produce them at a constant rate. Plus, you know exactly what's going into it so you can figure out if you want to add or substitute some things. Effect on Biological Activity:
Chemical fertilizers kill the microorganisms in the soil. It is one of the advantages of organic fertilizers that they boost microbial activity in the soil. These microbes help in degenerating the complex compounds present in the organic fertilizers. Effect on Soil:
Overuse of fertilizers is often a problem as excess nutrients are neither good for the overall composition of soil nor are they good for the plant. Organic fertilizers may also have a problem of overuse, but it is a slow nutrient releasing material, so the nutrients will anyway take some time to get absorbed. Effect on Environment:
It is one of the greatest advantages of organic fertilizers that they are easily available in nature, in plenty and with almost no adverse effect on the environment. Chemical fertilizers on the other hand might have the problem of nitrogen components seeping into...
