NPK fertilizer is a complex fertilizer comprised primarily of the three primary nutrients required for healthy plant growth.

The agriculture перекормила 10 месячного ребенка симптомы relies heavily on the use of NPK fertilizer to meet global food supply and ensure healthy crops.


According to the IFDC, about half of the global population is alive as a result of the increased food production provided by the use of mineral fertilizers.

NPK Fertilizer: Components

There are numerous building blocks of life that plants need for healthy and optimum growth.

Without these nutrients, plants cannot grow to their full potential, will provide lower yields, and be more susceptible to disease.


The three most important nutrients, without any one of which plants could not survive, are referred to as the primary macronutrients: Nitrogen (N), Phosphorus (P), and Potassium (K).


Soils often lack these nutrients, either naturally, or as a result of over cultivation or other environmental factors.

Перекормила 10 месячного ребенка симптомы cases where soils are lacking, nutrients must be put back into the soil in order to create the перекормила 10 месячного ребенка симптомы environment for optimal plant growth.


Each of the primary nutrients is essential in plant nutrition, serving a critical role in the growth, development, and reproduction of the plant.


Nitrogen (N)

The Role of Nitrogen in Plants

Nitrogen is a key component in many перекормила 10 месячного ребенка симптомы the processes needed to carry out growth.

In particular, nitrogen is vital to chlorophyll, which allows plants to carry out photosynthesis (the process by which they take in sunlight to produce sugars from carbon dioxide and water). Nitrogen is also a significant component in amino acids, the basis of proteins.

Nitrogen also aids in the compounds that allow for storage and use of energy.


One study looked at US cereal yields and how they were affected by omitting nitrogen fertilizer. The study estimated that without nitrogen, average yields for corn declined by a staggering 41%, rice by 37%, barley by 19%, and wheat by 16%.

Sources of Nitrogen

While nitrogen can be taken in and converted into a usable nutrient from the atmosphere, and may be naturally present in soils, it is almost always desirable to supplement nitrogen to ensure plants have the optimum amount available to them.

The following materials can be included in NPK blends as a source of nitrogen:

Common Inorganic Sources of N in NPK Blends

  • Urea
  • Urea Ammonium Nitrate
  • Anyhdrous Ammonia

Common Organic Sources of N in NPK Blends

  • Manure
  • Compost
  • Blood Meal
  • Feather Meal

Phosphorus (P)

Phosphorus also plays a role in an array of functions necessary for healthy plant growth, contributing to structural strength, crop quality, seed production, and more.

Phosphorus also encourages the growth of roots, promotes blooming, and is essential in DNA.


The transformation of solar energy into usable compounds is also largely possible because of  phosphorus.

Sources of Phosphorus

Like nitrogen, phosphorus in NPK fertilizer can come from both organic and inorganic sources:

Common Inorganic Sources of P in NPK Blends

The primary source of inorganic phosphorus is phosphate rock.

Crushed phosphate rock can be applied to soils directly, but it is much more effective if processed to be more readily available for plant uptake.

Common Organic Sources of P in NPK Blends

  • Manure
  • Compost
  • Biosolids
  • Blood Meal
  • Bone Meal

Potassium (K)

Potassium is also vital in a variety of other перекормила 10 месячного ребенка симптомы that contribute перекормила 10 месячного ребенка симптомы growth and development.

Potassium is often referred to as the “quality element,” because of its contribution to many of the characteristics we associate with quality, such as size, shape, color, and even taste, among others.


Plants low in potassium are stunted in growth and provide lower перекормила 10 месячного ребенка симптомы of Potassium

Potassium can be obtained from a wide range of sources, both organic and inorganic:

Common Inorganic Sources of K in NPK Blends

The primary inorganic source of potassium for use in NPK fertilizers is potash.

Like phosphate rock, potash is mined all over the world and processed into a more refined product. Potassium can also come from potassium перекормила 10 месячного ребенка симптомы, langbeinite, and granite dust.

Common Organic Sources of K in NPK Blends

NPK Fertilizer Production

NPK fertilizer is available in liquid, gaseous, and granular form, with granular being the most common.


Many methods exist for producing a granular NPK fertilizer.

Individual components may be produced separately and blended together in specific formulations to create target nutrient ratios, or grades. Or, all-in-one granules containing the desired ratio in each granule may also be produced. The most common approaches to producing granular NPK fertilizer include:


  • Pipe Reactor Granulation Systems
  • Drum Granulation Systems
  • Mixer-Dryer Granulation (Incorporating a pug mill) Systems
  • Disc Pelletizing Systems
  • Spherodizer Granulation Systems
  • Prilling Systems


While NPK fertilizers are comprised mainly of the three primary nutrients, flexibility in processing allows various other micronutrients to be incorporated into the blend.

For example, NPKS has been gaining popularity in response to the sulfur deficient soils resulting from the Acid Rain Act.


Specialty fertilizers, or fertilizers formulated to suit the unique nutrient needs of a particular location, are also becoming more popular.
