What are the limits of inorganic fertillizers?

Answer 1

Well inorganic fertilizers are known to work faster than organic fertilizers but they have their disadvantages...

(1) Because they are soluble they can be easily dissolved in water and washed away. These fertilizers are known to run off into streams and rivers and cause problems to the wildlife there.

(2) Inorganic fertilizers kill the microorganisms in the soil. The organisms are responsible for the breakdown of organic matter and the subsequent release of nutrients into the soil. When these organisms are killed off the soil becomes less fertile.

(3) It is claimed that the chemical fertilizers when absorbed not only assist in growth but also contaminates the plants. This contamination is then passed on to us when we consume these plants.
