Essay On Fertilisers

Fertilisers are chemicals that are added to the soil for increasing the fertility/ productivity of the soil. In India fertilizers are used in large numbers. The most common and highly used and produced are Urea and Single Super Phosphate. They are used for the thriving growth of plants. They increase the productivity and fertility of the soil. They provide crops with Nitrogen, Phosphorus and Potassium, which are most important elements for a plant’s growth. In today’s world all most all crops are sprayed with fertilizers to increase its productivity. But the most heavily feeded crops are: (Heavy feeders : Broccoli, Brussels sprouts, Cabbage, Cantaloupe, Cauliflower, Corn, Cucumbers, Eggplant, Kale, Kohlrabi, Onions, Peppers, Rhubarb, Squash, Tomatoes, Watermelon, Wheat, Rice etc.)1

Effects of fertilizers: (Weakens the Quality of Soil- Though

Diseases, pests and weeds should be controlled. Proper supply of balanced nutrition. Soil test to be done once in three years. Crop rotation is the best idea to keep up the fertility of the soil. Use of leguminous plants that have nodules in its roots that contain a bacteria Rhizobium that helps fixing atmospheric nitrogen in its root nodules and thus enriching the soil with nitrogen. Use of animal manures and putting biodegradable on the soil to make it more fertile. And Alternate Farming is also a very good way of reducing the use of fertilisers.) 4.

Advantage and Disadvantage of Fertilisers and Solutions:

(Fertilisers: Advantage-

 It can be made much faster unlike natural fertilisers.

 The NPK content of a chemical fertiliser is much more than natural fertiliser.

 If the NPK content of soil is according to the crop then the yield will be very good.

Disadvantage-

 Excessive use can increase the acidity of the soil.

 Some fertilisers contain filers other than NPK that can harm the human body
