There are two types of fertilizers, which are chiefly used by plant growers, i.e., organic and inorganic. The latter, also known as a chemical or synthetic fertilizers are artificially made in labs, and contain all the vital nutrients like nitrogen, phosphorus, potassium, etc., which are present in the organic ones.
Advantages and Disadvantages
These nutrients do not need to be broken down into primary nutrients for absorption by plants. Organic fertilizer effects can get delayed, and by that time a plant can die completely.
They are easily available at most gardening stores, and hence, are quite convenient to use. On the other hand, the decomposition process in making organic fertilizers is time-consuming, which delays their manufacturing.
The main disadvantage of inorganic fertilizers is they cost much higher than organic ones. If someone uses them in bulk, organic fertilizers are more cost-effective. The inorganic fertilizer nutrients are washed away, and might seep into the soil and pollute the groundwater. This is called leaching, which is more prevalent when inorganic ones are used.
The nutrients are already in their most basic components, and hence, can be washed away easily, if the plant roots are over watered or are watered with force.
These chemicals can contain certain compounds and salts, which a plant is unable to absorb, and hence, are left behind in the soil. With time, these compounds build up in the soil and can even change its chemistry. This can render the soil less than ideal for future plantations.
Lastly, over usage of inorganic fertilizers can prove to be detrimental for the plants. Too much of it can burn or destroy the plant structures, including the roots, which can hamper the overall development of plants.
