Is urea the same thing as ammonium nitrate?
Ammonium sulfate is not a slow release fertilizer. Specifically, ammonium nitrate, ammonium sulfate, liquid nitrate, urea and urea-ammonium are quick release forms of nitrogen fertilizer. They are soluble. They tend to solve lawn problems, as do the slow releasing natural organics, polymer and sulphur coasted urea, and urea-formaldehyde.
Ammonia is used in the manufacture of such things as : Fertilisers, such as ammonium sulfate, ammonium nitrate, ammonium hydrogen phosphate, and urea. Nitric acid, which is used to manufacture Ammonium nitrate fertiliser. Dyes. Fibres and plastics. Explosives, such as ammonium nitrate, trinitrotoluene (TNT) and nitroglycerine. Cyanides, which are used to manufacture synthetic polymers, such as nylon and acrylics. Extract gold from ore bodies.
A fertilizer that is high in nitrogen is what is best for olive trees (Olea europea). Specifically, olive trees accept a variety of soils and growing conditions. They are not needy for fertilizer. But they benefit from inorganic or organic fertilizers that are high in nitrogen. In terms of inorganic fertilizers, they flourish under applications of ammonium nitrate, ammonium phosphate, ammonium sulfate, calcium nitrate, potassium nitrate and urea. In terms of organic fertilizers, they handle…
Chemical fertilizer is any inorganic materials that is inserted into the soil for the growth and cultivation of plants. Examples are ammonia, ammonium sulphate, potash, urea, sodium nitrate, ammonium nitrate. The main role plays by the substance called nitrogen which are used in all these chemical fertilizers that helps to acidify the soil, very useful for the growth and stability of plants. I hope that will enough to clarify your point.
If Urea is used, it should be incorporated into the soil on the day of Application Calcium nitrate fertilizer should not be mixed with urea, because the combination of the two fertilizers will generate the precipitation of calcium and plants can not absorb. Urea should not be mixed with other chemicals such as KCl, SSP or TSP.
ammonium ion, which is the end product of amino acid degradation, is toxic if allowed to accumulate. the urea cycle is a pathway that detoxifies the ammonium ions by converting it to urea - which is then transported to the kidneys to form urine... the function is to remove nitrogen waste from the body and avoid toxicity
In cold packs is used Ammonium nitrate. It's dangerous because it can explode. But for this it must be absolutely dry. In a cold pack it is in a water solution. Nevertheless you shouldn't eat it or contact it a long time with your skin. In case of a damage of the cold pack you can just wash it away with water.
It's not entirely true to say, "...regularly add nitrate fertilizers..." since farmers in the US generally select the kind of fertilizers to use based on the nutrient needs of the crop, timing of application, and price of the fertilizer material. Nitrate fertilizers are one form they can use to get nitrogen, possibly the single most important nutrient, to their crops. However, nitrates are not always the most appropriate form to use, and so they also…
Examples include Urea [CO(NH2)2], Potassium Nitrate [KNO3] and Ammonium Nitrate [NH4NO3]. All are commonly found in "Instant cold packs" that become cold when you rupture the inner bag by depressing the pack gently but firmly. When then inner water makes contact with the chemicals listed above inside the outer bag of the pack, the endothermic reaction begins. This is the source of the cold temperature these types of Instant Cold Packs produce.
It is through one reaction which releases heat and another which absorbs it that urea is synthesized in industry. Specifically, the first reaction involves ammonia and carbon dioxide. The energy release results in the formation of ammonium carbamante. The second reaction will break above-mentioned compound down into urea and water.
According to what I could find, the ingredients are as follows: Ammonium phosphate Urea Potassium chloride Boric acid Copper sulfate Iron EDTA Magnesium EDTA Urea phosphate Zinc sulfate Sodium molybdate The percentage breakdown is as follows: Total Nitrogen: 15% 9.2% urea nitrogen 5.8% ammonium nitrogen Available phosphate: 30%; Boron: .02%; Soluble Potash: 15%; Copper: .07%; Iron: .15%; Manganese: .05%; Molybdenum: .00005%; Zinc: .06%. ~Gotten from epinions.com~
Ammonium carbamate is a chemical salt resulting from the reaction of ammonia and carbon dioxide. The structure is: H2N-C(=O)-O(-)(+)NH4. Ammonium carbamate can be formed without any intermediates by passing ammonia gas over solid carbon dioxide (dry ice). In the real world, there is often water present and this complicates matters. Carbon dioxide and water can react to form carbonic acid, H2CO3. Carbonic acid is a diprotic acid and can react with 2 equivalents of base…
