Chemical Fertilizer vs. Organic Fertilizer Fertilizers are the protein supplements for your plants. Fertilizers are used to enrich the soil with nutrients that it does not inherently have. Fertilizers should be used strictly as a deficiency-buster. Excessive use of different types of fertilizers kills the naturally present ingredients in soil too. Organic fertilizers are made from naturally occurring substances, and include by-products or waste remains of the animals. Dead plants and dead animals cadaver are also often used as fertilizers in organic farming.
They are naturally chemical-rich and contain high amounts of nitrogen, phosphorus and potassium. On the other hand, the main difference between a chemical fertilizer and an organic fertilizer is that the chemical fertilizer comes out of a lab and the organic fertilizer comes from living beings. A chemical fertilizer is synthetically prepared to include the vital nutrients that are necessary for the plant growth process. All chemical fertilizers contain the normal NPK (nitrogen, phosphorus, and potassium) requirement and any other nutrients as required.
One effect of Chemical fertilizers on Biological activities is that it kills the microorganisms in the soil, which, on the other hand, is one of the advantages of organic fertilizers since they boost microbial activity in the soil. These microbes help in reducing the complex compounds present in the organic fertilizers. However, Organic fertilizers may have a problem of overuse, but it is a slow nutrient releasing material, so the nutrients will anyway take some time to get absorbed.
In addition to these Organic fertilizers has one of the greatest advantages, which is 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 groundwater streams or otherwise into the nearest lake or river and causing pollution. Organic fertilizers are also much cheaper compared to their chemical counterparts as they are easily available in nature and only require packaging. Chemical fertilizers need extensive research and production work making them much more expensive.
One of the benefits of chemical fertilizers is that it is custom-made for your requirement. If your soil is rich in nitrogen and potassium, what you need is a fertilizer that will take care of the phosphorus deficiency. Chemical fertilizers will give you the option of using phosphorus-rich fertilizers. Another advantage of chemical fertilizers is that while organic fertilizers have a low NPK ratio, the chemical ones have a very high ratio of NPK. So if you have a very unproductive soil, chemical fertilizers are what you need as they have an NPK ratio of nearly 60% while the most fertile of organic fertilizers can give only about 14%.
Lastly the Organic fertilizers take more time to release the nutrients, as they need microbial activity to get them working. However, Chemical fertilizers get moving instantly and release the essential nutrients into the soil. In conclusion, the Dilemma of whether choosing the chemical fertilizer or the organic fertilizer lies in your hands since both fertilizers has their advantages and disadvantages which means the decision varies between the type of person you are and also between what kind of soil you have in your backyard.
