The deficiency of nitrogen causes yellowing of older leaves, stunted plants, dormancy of lateral buds, purple coloration in shoot axis surface, wrinkling of cereal grains and inhibition of cell division.
PotassiumPotassium helps determine anion-cation balance in cells and is involved in protein synthesis, opening and closing of stomata, activation of enzymes and maintainence of turgidity of cells.If potassium is not enough, it leads to scorched leaf tips, shorter internodes, dieback chlorosis in inter-veinal areas, loss of apical dominance, bushy habit, loss of cambial activity, plastid disintegration and increase in rate of respiration.
PhosphorusPhosphorus is a constituent of cell membrane, certain proteins, all nucleic acids and nucleotides, and is required for all phosphorylation reactions.Its deficiency causes delay in seed germination, purple or red spots on leaves, dark green leaves, premature fall of leaf or flower buds.
Mostly from the soil. Many do this in association with fungi and/or bacteria.
In addition to sunlight, CO2 and water, plants need certain elements in order to produce the compounds that they require to live. The most needed are nitrogen, phosphorus, and potassium. There are a number of others. Fertilizers are an attempt to replace these elements into the soil so that plants can grow faster than they would if you waited for nature to replenish these things "normally" (mainly by decay). But if you add to much fertilizer then the plants can get "burned" and will lose productivity. Also Nitrogen, Phosphorus and Potassium are macro nutrients.
•Plants use inorganic nitrogen-containing ions nitrate (NO3- -plants ate the nitrate) and ammonium (NH4+) Some bacteria able to use atmospheric nitrogen (N2 gas) as a nitrogen supply -Jacob Hirth-

soil contains small bits of rock, plants, and animal remains, live animals
The most essential role of phosphorus in plants is to store energy and provide it again plant cells when they needed it. This is done through complex organic molecules commonly referred to as ADP (adenosine diphosphate) and ATP (adenosine triphosphate).
Plants need salts containing potassium, phosphorus, nitrogen and some other minor elements.
For plants, phosphorus is an important nutrient because they need it for cell division and growth. Without this nutrient, plants can exhibit signs of stunted roots and leaf problems. Two other important nutrients needed by plants are nitrogen and potassium.
There are no three main chemical elements that plants need, there are many more. Every living thing MUST have at least carbon, oxygen, phosphorus, nitrogen, hydrogen and sulphur. A very common fertilizer used by farmers is NKP which has Nitrogen (N), Potassium (K) and phosphorus (P).
Fertilizers provide the nutrients which plants need. The principle ones are nitrogen, phosphorus and potassium. Nitrogen is needed to make proteins, phosphorus is needed for nucleic acids, and potassium has many roles including controlling the opening and closing of stomata. Intensive gardening and agriculture often remove these nutrients from the soil.
Plants need 13 different minerals to survive. (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, chloride, zinc, and molybdenum)
Fertilizer is made of potassium, nitrogen, and phosphorus. However some plants need other nutrients such as calcium, magnesium, sulfur, iron, copper, chloride, manganese, and molybdenum. Plus plants get carbon and water (H2O) from the soil.
In addition to sunlight, CO2 and water, plants need certain elements in order to produce the compounds that they require to live. The most needed are nitrogen, phosphorus, and potassium.

it is the combination of nitrate,potash and phosphorous used for agriculture
three primary nutrients which plant need for their growth are : 1.NITROGEN (N) 2.PHOSPHORUS (P) 3.POTTASIUM (K)
Nope you need phosphorus for buds not nitrogen
Nitrogen (N), phosphorus (P), and potassium (K) are the main nutrients that plants need to survive. Complete fertilizer contains those three ingredients and they are listed clearly as the N-P-K ratio. So, if a package of fertilizer states that its N-P-K ration is 10-6-6, then the fertilizer contains 10% nitrogen, 6% phosphorus, and 6% potassium. Water-soluble nitrogen satisfies the plants needs quickly, while insoluble nitrogen must be broken down by organisms in the soil before the plants can be fully satisfied.
Plants get nitrogen and phosphorous from the soil. If not replenished by decomposing biomass, these nutrients must be replenished via fertilizer application to insure proper plant growth.Plants get their carbon from the air (CO2) so adding carbon to the soil wouldn't help plants much.
