2. What Are Different Types of Fertilizer?
Fertilizer is material that is applied to the soil or sprayed on crops aboveground directly or
indirectly in order to supply nutrients, increase crop yields and improve product quality.
Direct fertilizer supplies essential nutrients to crops, including NPK fertilizer, compound
fertilizer and micro-element fertilizer, etc. Indirect fertilizer is used for improving soil
physical and chemical properties, thereby making growth condition of crops better, such as
lime, gypsum and bacterial fertilizers. Fertilizer is in a variety of classification method and
types, while having great difference in ingredient and chemical property. What are different
types of fertilizer? How to classify the fertilizer? This question is explained in further detail
below.
Inorganic fertilizer
Inorganic fertilizer or chemical fertilizer contains one or more nutrient elements for crops
growth, which is made by chemical means. It includes nitrogen fertilizer, phosphate
fertilizer, potash fertilizer, micronutrient fertilizer and compound fertilizer, etc. The
fertilizer is characterized by simple component, high nutrients and long fatty effect.

3. What Are Different Types of Fertilizer?
Nitrogen fertilizers
Nitrogen fertilizers contain nitrogen that crops need during development. Nitrogen plays a very
important role for crops growth, which is part of amino acids in plants and is a component
constituting the protein. Meanwhile, it is constituent part of chlorophyll that tips the balance in
the process of photosynthesis. Nitrogen can also help crops sub-colonization. Nitrogen fertilizer
can not only increase production of agricultural products, but also improve the quality of
agricultural products.
1.Ammonium nitrogen fertilizer
Ammonium nitrogen fertilizer contains ammonium bicarbonate (NH4HCO3), ammonium sulfate
{(NH4) 2SO4}, ammonium chloride (NH4Cl), ammonia (NH3.H2O), ammonia (NH3) and so on.
Ammonium nitrogen is easy to be adsorbed by soil colloids, partially into the clay mineral
crystal layer. Ammonium nitrogen becomes nitrate easily by oxidation. Ammonia losses
volatilizes in an alkaline environment. When crops absorb excess ammonium calcium,
magnesium and potassium, it cuases a certain inhibiting effect. Ammonia has a strong irritating
odor, corrosiveness and volatileness. Therefore, it can not be directly used for fertilizing. It is
available after configured to dilute ammonia.

4. What Are Different Types of Fertilizer?
☆Ammonium bicarbonate
Ammonium bicarbonate is white compound and crystal in granularity, clintheriform and
columnar. Aqueous solution is alkaline. Because of unstable nature, it is decomposing into
carbon dioxide, ammonia and water above 36℃.Decomposition is finished at the temperature of
60℃. Nitrogen is used for a variety of soil. It can provide ammonium and carbon dioxide for
crops growth. Because of low nitrogen content, it is easy to agglomerate. It not only promotes
crop growth and photosynthesis, but also helps crops come into leaf.
☆Ammonium sulfate fertilizer
Ammonium sulfate fertilizer is white orthorhombic crystal, which is soluble in water and
insoluble in alcohol. Ammonium sulfate is mainly used as fertilizer in agriculture. The advantage
of the fertilizer is relatively small hygroscopicity, not easy to agglomerate. Compared with
ammonium nitrate and ammonium bicarbonate. Ammonium sulfate has good physical properties
and chemical stability. Ammonium sulfate fertilizer is readily available fertilizer and good
biological fertilizer. The reaction in the soil is acidic so that the fertilizer is fit for alkaline soils
and carbonaceous soils. The disadvantage is that nitrogen content is low.

5. What Are Different Types of Fertilizer?
☆Ammonium chloride
Ammonium chloride is white crystal or colorless
crystal powder. Hygroscopicity is small, but it can
absorb moisture being caking in wet rainy weather.
Powdered ammonium chloride is easily deliquescent,
qualified products even worse. Moisture absorption
point is generally about 76%. Therefore, the
fertilizer should be kept in dry place. It can be used
as fertilizer. Avoid using ammonia fertilizer with
alkaline fertilizer. It is better not to apply the
fertilizer in saline-alkali soil as it may reduce
fertility.

6. What Are Different Types of Fertilizer?
2.Nitrate nitrogen fertilizer
Nitrate nitrogen fertilizer includes nitrate fertilizer sodium nitrate (NaNO3),
calcium nitrate {Ca (NO3) 2} and ammonium nitrate (NH4NO3), etc. Nitrate
nitrogen dissolve easily in water and moves fast in soil. It not only promotes cation
absorption, but also facilitates the synthesis of organic anion. For instance, corn
and wheat prefer nitrate nitrogen fertilizer. Under the condition of equal nitrogen
amount, yield-increasing effect of nitrate nitrogen fertilizer is more prominent than
other nitrogen fertilizers. Vegetables have strong preference for nitrate nitrogen. In
hydroponic experiment, as long as the nutrient solution is added nitrate, vegetables
grow normally without ammonium or urea nitrogen. Simultaneously, tobacco
responds to nitrate well. Applying nitrate nitrogen fertilizer increases output of
tobacco and improves its quality.

7. What Are Different Types of Fertilizer?
☆Sodium nitrate
Sodium nitrate is colorless transparent or white rhombohedral
crystal. It is easy to deliquescent. Under the condition of small
amounts of sodium chloride with impurities, deliquescence of
sodium nitrate would greatly increase. Sodium nitrate helps
combust, so it should be stored in a cool well ventilated place. It is
used as readily available fertilizer, especially pertinent in beets,
radishes and so on.
☆Calcium nitrate
Calcium nitrate is a typical fast-acting foliar fertilizer. It can
successfully act on acidic soil because calcium can neutralize soil
acidity. It is convenient for regeneration fertilizing of winter crops,
additional fertilization and excessive consumption of alfalfa growth.
In addition, it is widely used for sugar beet, fodder beet, poppy and
corn, supplying calcium for crops.

3.Amide nitrogen fertilizer
Urea, also known as carbamide, is a white crystal and one of the simplest organic
compounds. The nitrogen content of urea is 46%, which is the highest in solid nitrogen
fertilizer. It is the final product of protein metabolism in mammals and some fish. As a
neutral fertilizer, urea is suitable for a variety of soil and plants. It is easy to save and
use. Because of small destructive effect to soil, it is the chemical fertilizer with heavy
usage. Urea is the most common nitrogen fertilizer. Urea is suitable for all crops and
soils, which is used for base fertilizer and additional fertilizer.
Urea is used as base fertilizer and topdressing, sometimes as seed fertilizer. Under
normal circumstances, urea conversion needs 7-10 days at the temperature of 10℃，4-
5 days at 20℃, and only two days at 30℃. When urea is converted to ammonium in the
soil, it can be absorbed by seedlings in quantity. Therefore, the utility of urea fertilizer
should be a few days earlier than the other administration.

9. What Are Different Types of Fertilizer?
Phosphorus fertilizer
Phosphorus is the the main nutrient in phosphorus fertilizer. Fertilizer efficiency depends
on effective phosphorus pentoxide content, soil properties, fertilizing method and crop
strains, etc. Phosphorus is a component of the cell protoplasm in plants. It plays an
important role in cell growth and proliferation. Phosphorus is also involved in
photosynthesis, the use of sugar and starch and energy transfer. Phosphate fertilizer also
promotes the growth of plant root systems, making the plant ripe early. In the fruit stage,
massive phosphorus transfers to the grain, making seed full.
1.Water soluble phosphorous fertilizer
This kind of fertilizer is soluble in water, having high fertilizer efficiency. The main
products are calcium superphosphate and triple superphosphate.

10. What Are Different Types of Fertilizer?
2.Mixing soluble phosphate fertilizer
Nitrophosphate is the fertilizer that obtained by decomposition nitric acid, while N/P ratio
is 2:1. The use of the fertilizer can supply trace elements in the soil. It can also significantly
improve the quality of agricultural products. Nitrophosphate applies not only to wheat, corn,
rice and other food crops, but also for rape, tea, cotton, garlic, banana, litchi, apple,
watermelon, grapes and other industrial crops. It should be deep placement, casingsoil,
deep application of base fertilizer, to avoid contacting with the seeds or roots directly. It is
generally used as base fertilizer for common field crops and top application for industrial
crops. It is better to apply frequent, small amounts of fertilizer, which aims to improve the
utilization of fertilizer.
3.Citrate-soluble phosphatic fertilizer
This kind of fertilizer is insoluble in water. It mainly contains precipitated phosphate, steel
slag phosphate fertilizer, calcium magnesium phosphate and defluorinated phosphate
fertilizer. Generally, it is applicable to the acidic soil, so it should be used for base fertilizer.
It can be dissolved by organic acids that are secreted by soil and plant roots , and then it is
gradually absorbed by crops.

11. What Are Different Types of Fertilizer?
Potassium fertilizer
Potassium is the primary nutrient in potash fertilizer. Potassium in plants usually
accounts for 0.2% ~ 4.1% of dry matter, second only to nitrogen. In plant growth
and development, potassium is involved in the activation of more than 60 kinds of
enzymes, photosynthesis, assimilate transportation, carbohydrate metabolism and
protein synthesis.
1.Muriate of potash
Potassium chloride is chemically neutral and fast-acting fertilizer, which is well
suited for rice, wheat, cotton, corn, sorghum and other field crops. Because of
physiological acidity, potassium can be used in neutral calcareous soils. It can be
used as base fertilizer or topdressing. Because potassium chloride fertilizer contains
a large amounts of chloride, it will affect the growth of seed germination and
seedling.

12. What Are Different Types of Fertilizer?
When it is used as base fertilizer, it should be applied to arable soil 10-15 days
before sowing. It should be used early in order to leach chlorine ion to lower
soil by rain or irrigation water, removing or reducing damage to crops.
2.Potassium sulphate
Potassium sulphate is one kind of potash fertilizer. Potassium sulphate
consumption is far less than potassium chloride, which is less than 10% in
international potash fertilizer market. It is suitable for a variety of crops,
especially for tobacco, sugarcane, potato, sweet potato, grapes, tea and
cruciferous crops (such as rape, beans, etc.). It is generally used for dry land
rather than paddy field.

13. What Are Different Types of Fertilizer?
Organic fertilizer
Organic fertilizer is commonly known as farmyard
manure or natural fertilizer, mainly from animals and
plants. When it is applied to soil, it can supply carbonic
materials for plants growth. It includes a variety of
organic acid and rich nutrient elements. It not only
provides complete balance of nutrients, but also has high
manurial effect. Organic fertilizer can increase the
content of organic matter, promote microorganism
reproduction and change soil physical and chemical
properties. Therefore, it is the main nutrient for green
food.

14. What Are Different Types of Fertilizer?
1.Agricultural waste
Some agricultural wastes are good materials for organic fertilizer, such as straws, bean pulp, and
cottonseed meal and so on. The wastes play an unique role in increasing soil nutrient and
improving soil structure.
The main manure ways are used directly to field. The technology is simple to operate, while
saving time and labor. Related experiments have shown that the soil porosity increases 2.1% to
4.1% after straw using to field for 2 to 3 years, organic material increasing 0.5 ~ 1.7g / kg,
rapidly available potassium increasing 15.0 ~ 18.7mg / kg.
2.Livestock manure
These materials include pig manure, chicken manure and rabbit manure, etc. Livestock manure is
one of natural fertilizer in agriculture.
Untreated livestock manure contains hazardous substance, such as escherichia coli, nematode
and eggs. The application of untreated excrement rises temperature after fermentation, causing
seedling burnt. To improve efficiency and reduce harm to crops and the environment, animal
dung should be applied to field after complete composting.

15. What Are Different Types of Fertilizer?
3.Industrial waste
Some industrial waste are good materials for organic fertilizer, such as distilers’ grains, vinegar
residue and sugar-free grains. On the one hand, the use of wastes in agriculture increases
resource utilization rate and reduces environment pollution. On the other hand, it reduces the
burden on industry and changes waste material into things of value.
4.Municipal sludge
Because of growing sewage treatment works, the production of municipal sludge is increasing
year by year. Many people pay more attention to how to use it reasonably. Applying municipal
sludge into agriculture is a good choice for urban construction.
River muck and sewage can be made into organic fertilizer. Because of complete component of
the sludge, it just meets the requirements of nutrients in plants growth. Therefore, processed
sludge can be used as fertilizer. It contributes to soil amelioration as well as reducing pollution.
Not only solving the problem of waste treatment, but also is good for plants growth.
