Hint: Fertilizers are chemical substances supplied to the crops to increase their productivity. These are generally used by farmers to increase their crop yield. The fertilizers contain the essential nutrients required by the plants, including nitrogen, potassium and phosphorus. The organic fertilizer occurs naturally. They include manure, slurry, worm castings etc. organic fertilizers are good for soil and human health. But the plants cannot get sufficient nutrients from a small amount of organic manure, so synthetic fertilizers play a major role.

Complete answer:
Among the following options Calcium Ammonium Nitrate (CAN) is known as Kisan Khad or Farmer’s Compost. CAN is a calcareous and nitrogenous fertilizer. It consists of about 26 percent of nitrogen. It is commercially prepared from ground limestone. It is a neutral fertilizer with a pH of about 5-7 and is mostly suitable for fruits and vegetables to enhance the nutrient and colour. CAN is a highly efficient fertilizer because of its readily available nitrogen in the ammonium form. Since it has both calcium and nitrogen it is referred to as Farmer’s compost or the Kisan Khad.

Urea is also one of the most important and basic fertilizer used by farmers. This also provides nitrogen to the plants. Urea occurs naturally and also can be prepared industrially. Synthetic urea is produced from synthetic ammonia and carbon dioxide and can be produced as a liquid or solid. Naturally urea is produced when the liver breaks down protein or amino acids and ammonia. The kidneys then transfer the urea from the blood to the urine.
