Question

The most quickly available source of nitrogen to plants are
A. Nitrate fertilizers
B. Nitrite fertilizers
C. Ammonia fertilizers
D. Ammonium nitrate fertilizers

Answer 1

Hint:-A natural or chemical substance that is put on land or soil to make plants grow better is known as fertilizer. Fertilizers are very important for the growth of plants. Some fertilizers are natural whereas some are chemicals.

Complete step-by-step solution:-
Nitrate fertilizers - It is a chemical compound that includes nitrogen and oxygen. Nitrates are used as fertilizer in agriculture.
Nitrite fertilizers - farmers use nitrate fertilizers to help crops to grow and increase yields in plants , absorb nitrates from the soil and use them to build proteins. The plant may be eaten by animals and its biomass is used to produce animal proteins.
Ammonium hydroxide – It is commonly known as household ammonia. It is used. Everyday in household cleaning products . Ammonia is a basic building block for ammonium nitrate fertilizer, Which releases nitrogen, an essential nutrient for growing plants, including farm crops and lawns.
Ammonium nitrate fertilizers - Used to make fertilizers and explosives, And as a nutrient in producing antibiotics and yeast. Ammonium nitrate is the ammonium salt of nitric acid, It has a role as a fertilizer. An explosive and as an oxidizing agent.
Nitrogen has to be converted to nitrate, in order to be used by plants. Hence, using nitrate fertilizers directly would be the quickest way to provide nitrogen to the plants.. ammonium nitrate is an important fertilizer with the NPK- rating 34-0-0 ( 34% nitrogen) . It is less concentrated than urea. (46-0-0) 46% of urea. giving ammonium nitrate a slite transportation disadvantage. ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere. during on whether it is best to apply urea soon before the rain is expected or to cover it with soil to minimise nitrogen loss.
So from above discussion we can conclude that correct answer is option A
Nitrate fertilizers

Note:- The chemical compound ammonium nitrate, the nitrate salt of ammonium. It is a white crystalline solid and is highly soluble in water. It is predominantly used in agriculture as a high- nitrogen fertilizer. nitrate fertilizer preferred due to the highest absorbing ability of nitrates by plants, then in any other form.
