What is difference between urea and NPK fertiliser?

Urea is nitrogen fertilizer with an NPK (nitrogen-phosphorus-potassium) ratio of 46-0-0. The chemical formula of the urea is close in composition to the organic formulation of the urea, which also provides a number of advantages in the mass use for feeding crops. Although urea is naturally produced in humans and animals, synthetic urea is manufactured with anhydrous ammonia.

What is NPK and what does it do for plants?

Why Fertilizers?

Farmers on a large scale have started to use fertilizers daily because of their enormous range of benefits. Nearly every garden today – from small home gardens to large agricultural farms – have started to adopt the use of fertilizers to enhance their yield.

Why is it important to add fertilizer to plants?

If a plant lacks phosphorus there might not be symptoms of it as clear as nitrogen deficiency. There may appear minor signs of discoloration on the plants but by the time you recognize them, it would be too late. That is why it’s really important that you add fertilizers regularly to your plants. Phosphorus is one of the few components that last for a plant’s entire lifecycle.

How does nitrogen help plants?

Nitrogen goes through a series of transitions to provide these proteins to the plants . There are also many organisms present inside the soil which can slow the growth of the plant or even eat up the soil. Nitrogen-rich compounds make sure this isn’t possible, by immobilizing them further boosting the plant’s growth.

How do nitrogen rich compounds help plants grow?

Nitrogen-rich compounds make sure this isn’t possible, by immobilizing them further boosting the plant’s growth . Once these organisms are not able to feed on the plant anymore, they die and get decomposed into the soil as inorganic matter.

What are the three components of fertilizer?

For a plant to grow in optimal states, nitrogen, phosphorus, and potassium are needed.
