Common fertilizers available in Pakistan for crops, vegetables, flowers and herbs use

Those manufactured locally include urea, calcium ammonium nitrate (CAN) and ammonium sulphate (AS) as straight nitrogen fertilizers. Single superphosphate is the only straight phosphate fertilizer and nitrophos is NP, a complex fertilizer. All other fertilizers are imported. Recently the production of SSP and AS has been stopped due to high cost of production. These were very good fertilizers and in future, farmers of Pakistan will have no access to them. The grades of fertilizers available in Pakistan are listed in Table-1

This is the most concentrated solid straight nitrogen fertilizer. Its prills or granules are white in colour and free flowing. Urea is readily soluble in water.

[products limit=”3″ columns=”3″ orderby=”date” order=”DESC”]

It contains 46 percent N in amide (NH2) form which is changed to ammonium (NH4+) in the soil.

Agricultural Use:

Urea is a concentrated straight nitrogenous fertilizer that contains 46% nitrogen, which is a major plant nutrient. Nitrogen is a vital component of chlorophyll which is necessary for the photosynthesis process. It is applied to promote vegetative growth of crops and orchards in splits (basal & top-dressing).

In irrigated crops, Mostly, Urea is applied on the standing crop followed by irrigation to minimize its losses. In rain fed areas, it is often spread just before rain to minimize losses through volatilization process.

Urea” produced by  is in prilled form and at FFBL in Granular form. Granular Urea has the advantage of ease of application on standing crops because of large size granules. Its efficiency is relatively better in high water demanding crops like rice.

Industrial Use:

Raw material for manufacturing of plastics, adhesives and industrial feedstock.

Because of its high water solubility, it is well suited for use in solution fertilizers or foliar sprays. Urea though alkaline in initial reaction leaves behind a slightly acidic effect in the soil after nitrification.

It also incorporates a small amount of loose acid and sulphur. Its production has been stopped in the country due to prime cost.

Single superphosphate (SSP) Ammonium sulphate (AS)

Ammonium sulphate was once probably the most necessary N-fertilizers however as a result of its low nutrient content material and relatively prime production value its production and Daud Khel has been stopped. It incorporates 21% of N and 24% of sulphur.

Ammonium sulphate is a white crystalline salt however now and again, it would have a grey, brown, red or yellow tint, which has no effect on its nutrient price. It is soluble in water and nitrogen on this fertilizer is instantly available to crops. This fertilizer has an acidifying impact, subsequently, its continuous use may be positive on alkaline soils.

Calcium Ammonium nitrate (CAN)

This fertilizer comprises 26% N, part of it’s in ammoniacal shape and half in nitrate form. Its granules and prills are gray or light brown in colour and unfastened flowing. The complete fertilizer is not soluble in water because of calcium but the nitrogen phase is readily soluble. By distinctive feature of the calcium on this fertilizer, it is roughly impartial in its reaction when implemented to soil.

SSP fertilizer used to be available in powder in addition to in granular shape. Its color could be gray or brown and it contains 16 to 20% P2O5. The phosphors on this fertilizer is quickly soluble.

This is a concentrated phosphorus fertilizer which comprise 46% P2O5 and nearly all of this phosphorus is in water soluble form.

TSP could be in powder as well as in granular form but the light gray granulated product has higher storage and handling properties and is free flowing.

Sulphate of potash(SOP)

SOP is to be had as a white crystalline salt or in granular shape and accommodates 48 to 52% K2O and 18% of sulphur. It is solule in water. In Pakistan that is the one potassium fertilizer which is advisable for all crops but on a global scale its use is proscribed to positive plants which are delicate to chloride i.e. tobacco, potato, fruit and veggies.

Agricultural Use:

SOP is an important source of Potash, a quality nutrient for production of crops, especially fruits and vegetables.  SOP contains 50% K2O in addition to 18%

Sulfur, which is an important nutrient especially for oil seed crops because of its role in increasing the oil contents. It has also an additional advantage of ameliorating effect on salt-affected soils. Sulfur also helps in containing spread of fungal or other soil borne diseases. Potash is an important nutrient for activation of enzymes in the plant body, develops resistance against pests, diseases, stresses like water/frost injury and also helps in increasing sugar / starch contents in plants. It also improves quality and taste of vegetables / fruits.

 SOP is one of the finest quality products with less than 1% Chloride content being imported from European origin and preferred for the high value Tobacco crop.

Industrial Use:

Occasionally used in manufacturing of glass.

Diammonium phosphate (DAP)

This fertilizer comprises 18% N and 46% P2O5 , It is a readily water soluble fertilizer and each vitamins on this source are in plant available shape. The subject material is gentle brown, granular and loose flowing.

Agriculture Use:

Di-ammonium Phosphate (DAP) belongs to a series of water-soluble ammonium phosphates that is produced through a reaction of ammonia and phosphoric acid. DAP is the most concentrated phosphatic fertilizer containing 46% P2O5 and 18% N. It is recommended for all crops as basal fertilizer to be applied at the time of sowing for better root proliferation and inducing energy reactions in the plants. The solubility of DAP is more than 90%, which is the highest among the phosphatic fertilizers available in the Country; due to which it can also be applied post planting through fertigation. Further, on account of its nitrogen content; upon completion of nitrification process, the ultimate reaction of DAP is acidic.

Industrial Use:

Fire retardant used in commercial firefighting products. Other uses are as metal finisher, yeast nutrient and sugar purifier.

It leaves acidic effect in soil after nitrification of ammonium (NH4+). No deleterious affect on soil and crop has been reported because of its use. However, its direct contact with seed and germinating seedlings will have to be avoided as ammonia might cause harm.

These fertilizers are also called ammonium nitrate phosphates. In Pakistan, it is known as nitrophos and contains 23% and 23% P2O5 . Half the N is in ammoniacal form and the other part is in nitrate shape.

The water solubility of phosphorus in 23-23-zero grade is generally greater than 70 per cent.

Zinc Sulphate (27% Zinc)

Agricultural Use:

Zinc is a micronutrient fertilizer in the form of Zinc Sulphate Monohydrate (27%) in 3 Kg packing. It is an essential micronutrient required for plant nutrition, which plays a vital role in a number of growth processes especially in chlorophyll synthesis, proteins, activation of enzymes and plays important part in hormonal activity particularly auxins. Zinc deficiency is widespread throughout Pakistan and zinc deficiency in soil is translating as deficient element in human diet and livestock feed. In crops, its deficiency results in growth inhibition, leaf yellowing, less number of leaves and low crop yields. The zinc deficiency is causing different diseases in humans and livestock. Keeping in view the wide spread deficiency of zinc in Pakistan,  is providing high quality  Zinc. It is highly water soluble and can also be used as fertigation i.e. application with irrigation. It can be mixed with other fertilizers for broadcast in the field.

Boron (Boron 0.5%)

Agricultural Use:

Boron is a micronutrient fertilizer in the form of Di-Sodium Tetra Borate Decahydrate in 3 Kg packing. It is an essential micronutrient required for plant nutrition, which plays a vital role in a number of growth processes especially new cell development, fruit/seed setting, translocation of sugars, starches, nitrogen and phosphorous, nodule formation in legumes and regulation of carbohydrate metabolism. Boron deficiency appears in youngest leaves as wrinkled, often thicker and of a darkish blue green color. As deficiency progresses, the terminal growing point dies and flowers & fruits formation is restricted or inhibited; fruits remain very small and of poor quality. Keeping in view increasing boron deficiency in Pakistan soils,  is providing superior quality  Boron containing 10.5% Boron (Borax). It is soluble in water and readily available to plants. It is used as soil application alone or by mixing with other fertilizers.

Muriate of Potash (MOP)

Agricultural Use:

Potassium chloride (commonly referred as Muriate of Potash or MOP) is the most common potassium source used in agriculture, accounting for more than 90% of all potash fertilizers used worldwide.  MOP contains 60% K2O and is used mainly for fertilizing sugarcane, maize, fruit trees, vegetables and other field crops except tobacco.
