Organic fertilizers are generally much more expensive than chemical fertilizers, mostly because chemical fertilizers have more concentrated levels of nutrients per weight of product than organic fertilizers do.
But organic fertilizers have advantages. But they may cost more than chemical, or inorganic fertilizers, because they are less concentrated, supplying fewer nutrients pound for pound. Since many chemical/inorganic fertilizers are concentrated and very soluble, it’s easier to apply too much and damage your plants.
Similarly, what are the advantages and disadvantages of chemical fertilizers? Commercial chemical fertilizers are more expensive than natural fertilizers. They may contain ingredients that may be toxic to the skin or respiratory system. You also need to mix and measure them accurately. If you use too much, you can kill your plants.
Besides, why are organic fertilizers better than chemical fertilizers?
Organic fertilizers continue to improve the soil long after the plants have taken the nutrients they need. Therefore, the longer your soil is fed with organic fertilizers, the better its composition and texture. So, while inorganic fertilizer is cheaper in the short term, it adds less to the soil in the long term.
Why is chemical fertilizer bad?
The use of chemical fertilizers on crops can have adverse effects on waterways caused by chemical run off of the excess fertilizer. The over-abundance of nutrients in the water reduces the amount of oxygen. The existing organisms living in the water use up the oxygen that is left.
What are the three major types of organic fertilizer?

What are the disadvantages of organic fertilizers?
The biggest disadvantage of using an organic fertilizer is that it may not contain primary nutrients like nitrogen, phosphorous or potassium, also known as NPK. Manure-based fertilizers contain these nutrients and are still considered organic. However, many others don’t contain significant quantities of NPK.
Can you use too much organic fertilizer?
Excess fertilizer is bad for plants and the environment. Too much fertilizer may burn a plant’s roots and make the plant more vulnerable to insects and diseases. A soil test will show if you are using too much fertilizer. Even organic fertilizers, such as compost, can be overdone.

What is the importance of organic fertilizers in agriculture?
Natural fertilizers have immense benefits for the soil and crop production. They add soil organic matter, improve soil structure and preserve essential nutrients that crops need in order to grow well.
What makes a fertilizer organic?
Organic fertilizers are fertilizers derived from animal matter, animal excreta (manure), human excreta, and vegetable matter (e.g. compost and crop residues). Naturally occurring organic fertilizers include animal wastes from meat processing, peat, manure, slurry, and guano.
