What is quality or quality?
As a qualitative factor, we understand those fertilizers that meet the requirements of the government issued instructions. For example, let us suppose that the total nitrogen content of nitrogen content is 46.0% and the maximum bureau is 1.5% and the total moisture is fixed at 1.0%. If the quantity of nitrogen in the sample of urea fertilizer is less than 46%, if the amount of the bureau is more than 1.5% and the moisture content is more than 1.0%, then the fertilizer should not be standard.
 
Agriculture of Bangladesh is commonly used in urea, TSP, DAP, MOP, gypsum, zinc sulphate and briquette acids. The characteristics of the fertilizers and their effect on the production of crops are described below. Ultimately, the easiest ways to determine the value of these fertilizers are also described in a geographical way.

Urea fertilizer
Urea is a chemical fertilizer with very good nitrogen. It is produced as preield, granular, pellet, powder and tiny crystals. Easily melt or dissolve in water. Looks like white or in many cases colorless. There is no smell of the fertilizer. It is not acidic or alkaline.
 
To facilitate the use of urea preield (small grains <2mm) and grainy (2-5 mm) are marketed. IFDP is encouraging small entrepreneurs to market gourd urea or USG At present, arrangements have been made to set up 6000 exhibition exhibitions of 1.8-2.7 grams of urea by 1.8-2.7 grams through the Agricultural Productivity Development Accelerating Project (APR) in 22 districts (122 Upazilas of 20 districts of Mymensingh, Sherpur and South regions). Aus and aman paddy are recommended to apply 1 gram urea per 1 gram of 1.8 grams and 4 grams of Boro paddy at the rate of 2.7 grams.
 
The key to urea nutrition is to provide nitrogen, which promotes the growth of roots. Helps in the production of adequate leaflets. Participate in the production of protein and nucleic acids. Through the production of chlorophyll, the tree is given green color. Increases sugar production. Helps to increase the size of the fruit. Increases the absorption rate of all other essential components. Helps in producing Kushi.
 
Chlorophyll synthesis rate decreases when there is a shortage of nitrogen nutrient content on the ground. As a result, the tree lost its natural green color. The size of the leaves is reduced and the growth of the branch area decreases, thus the tree is depleted. The leaves of the tree fall from hazel to yellow to yellowish and fall in a while. Discoloration starts from the tip of the leaf. The stalk and branch branches are narrow. The pink or light red color is unusual. The median of the old leaves is yellowish-brown in color. Flowers and fruits are small. The yield decreases.
 
If the application of nitrogen is high, the structure and structure of the plant is weak. Flowers and fruits are delayed in production. Insects and disease attacks increase. If the leaf portion is heavy, the tree is tilted. Many nitrogenous fruits have many fruits.

TSP and DAP fertilizers
Phosphate-rich chemical fertilizers both on TSP (Triple Super Phosphate) and DAP (Diomphyan Phosphate) The usage of both fertilizers in Bangladesh is increasing day by day. These fertilizers are marketed as grains. There are 20 percent of phosphorus in this fertilizer. TSP consumes 13 percent of calcium and 1.3 percent of sulfur. DAP also contains 18% nitrogen in addition to phosphate, which is why it is a good fertilizer for lime clay soil.
 
TSP fertilizers are prepared by the reaction of phosphoric acid with rock phosphate. TSP fertilizer color is gray to dark gray. The essence of the acetic acid contains a frozen smell. This fertilizer melts easily in water.
 
DAP fertilizer is produced in reaction to ammonia and phosphoric acid. The fertilizer is easily soluble in water. The color of the fertilizer is usually white to dark gray. DAP also has a scorching odor.
 
Phosphorus participates in cell division. Carbohydrates help in production and adoption. Promotes the increase in roots. Strengthens the plant's structure and protects it from falling down. Prevent diseases and insects attacks. Enhance the quality of flowers, fruits and seeds.
 
Due to the deficiency of phosphorus on the soil, the growth of root and root is reduced. The growth of the tree is curved or rolled. The old page goes away in a while. Lateral pores and bacterial growth decreases. Flower production decreases. The leaves contain purple or bronze color. The surface of the leaves contains green and green in color. Blubber defects are seen on the edge of the leaves and dry. Disease resistance decreases
 
If the amount of phosphorus is more then the yield decreases. There is a sudden maturity in the tree. The growth of the tree decreases.

Mop fertilizer
MOP or muriate of potash is a potash fertilizer most commonly used. 50 percent of the aces are in the potash. Acar easily melts or dissolves in water. The color of the fertilizer is usually white to light or dark reddish and its shape is small to medium-sized crystalline.
 
Potassium plant protects the proximity of cells. The plant helps transfer or transfer starch content. Increases the effectiveness of iron and manganese. Helps to produce protein. Contains water absorption, acclimatization, and overall control of plants. Promotes disease resistance. Strengthen the plant's structure. Equalization of nitrogen and phosphorus absorption.
If there is a deficit of potash, discontinuation starts from old leaves. Dark blue leaves are visible. The cross-section of the leaves is seen as a brownish tissue. The surface of the leaf is seen to be crushed or folding. Trees contain distorted shapes. The growth of the trees with small intervals decreased and the main kayat fell to the ground. The tree is very sensitive in inclement weather. The outbreak of insects and disease increases.
 
The absorption rate of calcium and boron decreases in the supply of potash. The lack of boron becomes clear. The rate of water-emission decreases. The growth of the tree abnormally decreases.

Gypsum fertilizer
About 65,000 May of the country's only TSP fertilizer factory Ton gypsum is available as a by-product. 17 fertilizers contain 17 brinjal and 23 percent calcium. Because of the high moisture in the samples of fertilizers, it can not be stored in slacks for a long time. The actual gypsum fertilizer lays a bit of chicks in the light and the softness of the fertilizer is of soft nature. The fertilizer is like white or gray powder.
 
Sulfur participates in the production of meat. Helps in the formation of chlorophyll. The tree is green in color. Helps in seed production. Increase the quality of the crop.
 
If there is a lack of sulfur on the soil, green color of the tree is destroyed, the trunk is green and smooth. The leaves contain pale green or yellow shape. The tree increases the sugar and nitrogen.
 
If the level of gypsum applied is high, the root growth decreases. Physical growth decreases.

Zinc sulphate fertilizer
The zinc or zinc deficit of Bangladesh is being used in two types of Dental Fertilization. A zinc sulphate monohideret and the other zinc sulphate hepatohydrate. A small amount of other zinc fertilizers is applied directly to zinc and is applied directly to the tree. Zinc sulphate monohide has 36.0 percent zinc and 17.6 percent sulfur. On the other hand zinc sulfate hepatitis is present in the ratio of zinc and sulfur in the ratio of 21.0 and 10.5 percent. Zinc contains about 10 percent of the zinc.
The Zinc Sulfate Monohide Surface is actually produced in small crystal form. It is marketed as grains for the purpose of application to crops. The ingredients are colorless to whitish and have a lot of sugar. The water melts easily.
 
The zinc sulphate (hepatoid) is like a grain of crystalline sugar to see the fertilizer and is shabby. The actual hepatitis ZA fertilizer melts easily into the water and makes a transparent solution.
 
Zinc sulphate (monohide) fertilizer is used in soil more than zinc sulphate (hepatohydrate). Some spaces are applied even after spraying.
 
Zasta tree participates in creating different types of hormones. Helps in the production of chlorophyll. Increase the prevention of crop disease. Crop phosphorus helps control nutrients. Sham national vegetables significantly increases the yield.
 
If there is a shortage of dust on the ground, the leaves of the tree are found in the form of copper or stain. The form of petal leaf or rooftop signs is created. Discoloration starts from the beginning of the new leaves. Discolouration occurs intensely in interstate places.
 
If zinc is high then the toxicity of the tree is created. Extra zinc protein production causes inconvenience.

Boron fertilizer
Barley Acid and Salubar Fertilizers Used in the area of ​​Boron deficient boron fertilizer. Varic acid color is white. It is irregular and crystalline. Hot water melts completely.
Saline Fertilizer A superior boron fertilizer for the areas of boron deficiency. It looks like white, light, mixed powder, the suluvar melts completely in cold water and does not fall into any type of vessel.
Breast nutrition material helps in increasing the cells of plants. The leaves and flowers are colorful. The pollen is strong and healthy. Helps in the production of seeds and prevent chita.
 
In the absence of the boron, the tree nozzle dies, the stem contains black color. The root growth decreases. The cell wall is broken. The tree consists of a sprained sprain.
 
If the use of boron is more than the amount of brown leaves and the tip is damaged. The yield reduces a lot.

How to recognize quality fertilizers at the field level
Due to the huge demand for chemical fertilizers, many dishonest merchants market their adulterated fertilizer production and imported fertilizer to gain more profits. As a result the farmers' brothers are being deceived. Do not get the desired yield even after using fertilizers at the right level. As a result they are being economically damaged. On the other hand, there is a negative impact on land degradation and the production capacity is gradually decreasing. So if the farmer's brothers know the technique of identifying or identifying the quality, then you can get rid of the adulterated fertilizer deception. Below are some techniques to describe the fertile fertilizer.
 
Urea
Generally manufactured and imported urea fertilizers in the country are not generally adulterated. However, mixing small grains with Dolomite or cheaper chemicals, mixing urea with granules can be identified as adulteration by viewing the color.
 
The original urea fertilizer will not be crystal shaped in any case. It is marketed as grainy or preield. It easily melts in the water.
 
If one teaspoon of urea is poured into half a glass of water, then it will create a transparent mix of melt immediately. If you put hand on the solution, it will feel very cold.
 
Another simple test is that if some urea is kept in open containers, it will absorb moisture from the air and wipe it in a while. It will prove that there is no adulteration in the uriyara sample.
 
TSP
TSP contains smoldering smell. The fertilizer is easily soluble in water. When one tea teaspoon TSP is mixed in water, the dirty water will dissolve in the melt, whereas on the contrary, TSP water will be mixed with grinding solution. If the grains produced by FMP grains and drum soils, gypsum and dolomite are made in TSP, they will be stored under the glass in the form of granular form.
                                                                                       
Due to the fact that the actual TSP is more solid, it will not be easily broken when pressed between two old nails, but the transitive TSP will be broken easily due to its relatively soft. There may be different color variations of the adulterated TSP fertilizer. If the FM grains are mixed as adulterant, it will not break easily and will not dissolve in water.

DAP
The DAP fertilizer contains a tedious smell like TSP fertilizer. The fertilizer easily melts in the water.
 
If nitrogen is present in the original DAP fertilizer, then if you put some grains in the open on a paper, it will absorb moisture from the air and wither in a while.
 
If one tea teaspoon DAP fertilizer is mixed with lime, then if the smell of ammonia comes out, then the fertilizer is actually DAP.
 
Another simple test is that if one teaspoon DAP fertilizer is mixed in semi-glass water, it will be melted immediately to form a transparent solution, whereas a mixture of sulfur mixed with adulteration will make the grinding solution.
 
Mop
There is no smell of mop fertilizer, but if you give it, it is a taste. Keep moisture during the monsoon, moisture absorbs moist air from the air and gradually increase the amount of moisture content.
When half a teaspoon mop fertilizer is mixed in the water of the glass, the melting point will be formed immediately, and the adulterated MOP will absorb water in the form of insoluble matter such as sand, glass powder, small dilapidation stone, brick powder, etc. in the form of drainage. In the case of the original MOP fertilizer, it will feel cold when handing it to the glass, the counterfeit will feel less cold. If the mixture is mixed with red or any other color as adulterous, the color of the water will be accordingly and the color will disappear. If you put hand on the solution, the color will be drawn.
 
Gypsum
If one teaspoon of grapesum in a glass or china clay contain 10 drops of thin (10%) hydrochloric acid on the fertilizer, then if it is found to be dry, it can be assumed that the gypsum fertilizer is adulterated.
Sometimes, adulterated gypsum is made by mixing lime powder and clay powder.

Zinc sulphate fertilizer
Colorless small-scale crystal shape to see the actual zinc sulphate (monohide) fertilizer. It is also marketed as a grainer.
For a simple test one tea spoon will dissolve in semi-glass water, it will completely melt and the solution will be muddy. If the sample is the correct zinc sulphate (monohydrate), then the dark whey solution will gradually become clear from the bottom of the glass. If the sample is a violet zinc sulphate (Monohide), then after a while, the upper part of the dark muddy solution will slowly turn downwards towards the bottom of the glass. White small sized crystal shapes to see the original zinc sulphate (hepatoid). Mix one tea spoon zinc sulphate (hepatoid) in semi-glass water and the fertilizer will completely melt and there will be no contamination of the vessel.
 
The same amount of zinc sulphate (hepatohydrate) fertilizer zinc sulphate (weight is much lighter than the monohiderate fertilizer).
 
 
Boron fertilizer
Varic acid color is white. It is irregular and crystal shaped. If you want to rub a finger with some amount of acids, then you will feel the slippery oil oil. But the adulterated acids will not feel slippery oil oil. If one teaspoon of acetic acid is mixed in a glass of hot water, it will completely melt and there will be no sulfur under the glass bottom.
 
Sulfur boron looks like white, light, refined powder. If one teaspoon dissolves in cold water in the salubar glass, the actual solubor boron will completely melt and there will be no contamination of the containers. Mixing a pinch of barium chloride in the solution will not cause any degradation. If sodium sulfate is mixed in the sample, then the barium sulphate will fall down and the solution will immediately become white like milk.
