Why is urea better than other fertilizers?
Urea has the highest nitrogen content of all solid nitrogenous fertilizers in common use. More than 90\% of world industrial production of urea is destined for use as a nitrogen-release fertilizer. Urea is made up of 46\% nitrogen and is more widely available than calcium ammonium nitrate (CAN) internationally.
Why are Punjab farmers using more and more chemical fertilizers nowadays?
– The farmers in Punjab are now due to degradation of soil health are forced to use more chemical fertilisers for increasing the production level . – Due to this cost of cultivation is also increasing in Punjab.
Why does farmers use urea in their fields?
Urea is used in many ways to provide N nutrition for plant growth. It is most commonly mixed with soil or applied to the soil surface. Due to the high solubility, it may be dissolved in water and applied to soil as a fluid, added with irrigation water, or sprayed onto plant foliage.
Which fertilizer is best to the farmers and why?
Being ecologically and environmentally safe and non-toxic in nature, organic fertilizers are the best fertilizers for plants and crops in farming. Their regular usage doesn’t lead to pollution and contributes to the better tomorrow.
What are the advantages of urea fertilizer?
Urea has several advantages, including cost per pound of nitrogen, higher nutrient density and good handling and storage properties. The biggest disadvantage is the potential for volatilization. This occurs when urea is surface-applied and converted to ammonium carbonate by urease.
What are disadvantages of urea fertilizer?
Impurities and Improper Use of Urea Fertilizers Can Damage Plants. As with any source of nitrogen, urea itself can damage plants: nitrogen impairs or completely impedes seed germination, and too much nitrogen can give crops a “burn.”
What are the effects of chemical fertilizers in Punjab?
1. It causes ground water pollution by the process of leaching. 2. The chemicals react with clay to create hard layers of soil known as hardpan.
What are the demerits of using excess chemical fertilizers?
Disadvantages of Chemical Fertilizers……….
- Commercial chemical fertilizers are more expensive than natural fertilizers. They may contain ingredients that may be toxic to the skin or respiratory system.
- We also need to mix and measure them accurately. If we use too much, it can kill our plants.
What is the difference between NPK and urea?
1. Urea Has Not Always Been the Primary Source of Nitrogen to Crops. Urea, on the other hand, has an NPK grade of 46-0-0, making it more economical to transport. Ninety percent of synthetic urea produced now is for fertilizers.
Why are NPK Fertilisers important to farmers?
Fertilisers provide elements needed by plants to grow well, such as nitrogen, phosphorus and potassium. They can make crops grow faster and bigger so that yields are increased. The compounds used must be water-soluble so plants can absorb them through their roots.
Why farmers use fertilizers?
Fertilizers are added to crops in order to produce enough food to feed the human population. Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and to produce more food. Nitrogen is all around us and makes up about 78\% of the air you breathe.
