1. Leeching happens
Inorganic fertilizers contain nutrients that
have been broken down already into the most basic of its components for easy
absorption by the plants. Yet, it can also be washed away easily when watering
or irrigating the plants. This is called leeching.
This is called leeching, and it happens very often. When you’re using inorganic fertilizers you need to pay special attention to the roots of the plant when you’re watering it and not over water the area so that you’re not encouraging the leeching of the nutrients in the soil.
2. Some are not affordable
Generally, inorganic fertilizers are
inexpensive. Yet, some specially formulated inorganic fertilizers come at a
cost that are considerably higher than most.
3. Accumulation of toxic wastes
Inorganic fertilizers are not entirely
composed of the nutrients needed by the plants. It also contains salts and
other compounds. These are not absorbed by the plants so they are left behind
in the soil and build up over time.
When found in large amounts in the soils, these compounds can alter the chemistry of the soil that makes it less ideal for planting. Often times, the soil needs to be neutralized using other substances to return it to a normal state that is suitable for planting.
Furthermore, these toxic compounds may also get washed away when you water your plants and seep into groundwater. It has been reported that the toxic wastes from fertilizers contaminating the water we drink is bad for the health.
4. Too much is not a good thing
Fertilizers are good sources of nutrients for
plants. However, too much of it can also be harmful to the plants. Applying the
fertilizer directly to the plants may burn the delicate plant structures such
as the roots. This could affect the over-all development of the plant.
Inorganic fertilizers have both good and bad points. Should you consider using
them, better maximize and the advantages and try to prevent all its avoidable
disadvantages.
