Understanding the Two Types
Organic fertilizers are made from naturally occurring substances, and include by-products or waste remains of the animals. Dead plants and 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).
All of them contain the normal NPK requirement and any other nutrients as required. Let us compare the two types of fertilizers in the following sections:
Benefits of Organic Fertilizers
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 groundwater streams or otherwise into the nearest lake or river, causing pollution.
Organic fertilizers are 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.
Benefits of Chemical Fertilizers
It is custom-made for your requirement. Now 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.
Organic fertilizers may take more time to release nutrients as they need some microbial activity to get them working. Chemical fertilizers get cracking instantly and release essential nutrients into the soil.
