Dear Student, Advantages of Fertilisers: 1. They provide specific nutrient. 2. They are very much water-soluble, so they easily absorbed by the plants. 3. They show rapid actions. Disadvantages of Fertilisers: 1. Non-renewable material are used for production of fertilisers. 2. Leaching of fertilisers causing movement of hazardous material into river which causes eutrophication. 3. Excessive fertilization causes damage to the crops. Thank You!
