Three points of skillful application of urea

One is suitable for top dressing. Urea is a neutral fertilizer, less damage to crop leaves, but also easy to dissolve in water, strong diffusion, easy to be absorbed by the leaves, after entering the leaves is not easy to cause the phenomenon of plasmolysis, it is very suitable for extra-root fertilizer. However, urea with a biuret content of not more than 2% should be used to prevent damage to the leaves. Generally, the amount of fertilizer applied outside the urea root per acre is 0.5 to 1.5 kg. The spraying time is suitable after 4 pm, when the evapotranspiration is small, the leaf pores gradually open, and the diluted urea solution can be absorbed completely at one night, which greatly improves the utilization rate of urea. The second is to apply early and deep. One must apply early. Urea must be applied to the soil to have a conversion process that can be absorbed and utilized by crops. Therefore, if urea is applied for the same time as other nitrogen fertilizers, the maximum effect period of crops on nitrogen nutrient absorption will be delayed. The second is to deepen. Urea, whether it is basal or topdressing, should be deeply buried. Deep application can control the rate of hydrolysis of urea, so that it can evenly release nitrogen nutrition, prevent and control the loss of nitrogen volatilization, and improve the utilization rate. Third, it is not appropriate to express, dip, and apply seed immediately after application. First, it is inappropriate to express. In particular, saline land is less suitable for spreading on the surface. This is because ammonium carbonate, ammonium hydrogen carbonate, and ammonium hydroxide produced after the decomposition of urea are all unstable compounds. The second is not suitable for dipping and seed dressing. Urea contains a small amount of biuret, which has a toxic effect on crops. Soaking and mixing seeds with urea can destroy the protein structure of the seed, denature the protein, and affect the seed germination and root growth of seedlings. Third, it is not suitable to apply water immediately after application. After the urea is applied to the soil, it is dissolved in the soil solution in a molecular state before being converted into ammonium bicarbonate, which is not easily adsorbed by the soil. If irrigation is performed immediately, the fertilizer will be lost along with water, and the water will be sprayed for several days after the application.

The human tongue has a range of specific taste sensation neural receptors called taste receptors which are organized mainly as papillae on the tongue.  When stimulated by chemicals, natural or synthetic, organic or inorganic, cations or anions, the receptors send signals to the brain which interprets the stimulations as sweet, bitter, sour, salty, and savory (unami, meaty taste).   For examples, cations such as Na+ present in the table salt evoke the salty taste, and H+ presents in acids evokes a sour taste. Organic compounds such as sugars, dextrins and glycerol result in sweet taste, glutamate results in  savory taste, while many toxic compounds such as nicotine, morphine, caffeine, quinine, etc. result in bitter taste.  The sensation of tastes is an evolution trait for defense against poisons (normally evoke bitter taste), and for allowance of nutrients intake (normally evoke sweet or savory taste).  

 

Sugar is a natural sweetener as well as a nutrient consumed in vast quantity around the world.  It is one of the major calorie intakes by humans.  Over consumption of sugar often leads to obesity and other related medical conditions.  High blood sugar level (hyperglycemia) is a manifestation of the disease diabetic mellitus; if not managed properly, it could lead to a range of medical complications. To combat these medical conditions, high potency Sweeteners with no calorie or low calorie intake are often being used to substitute sugar.  Proper control of calorie intake, coupled with the use of these sugar substitutes has been very effective in managing the medical conditions.   

 

Besides the medical indications, using sugar substitutes brings the economic benefit of lowering the cost of many foods and consumer products, from soft drinks to cakes, pasties, and even toothpastes.  

 

A variety of chemical compounds, natural or synthetic, can evoke sweet taste, but not all of them are safe (for example lead acetate has a sweet taste but it is extremely toxic), nor are sweet taste specific (for examples, many of synthetic sweeteners can also evoke other senses of taste such as bitterness or metallic sensation).  Therefore, selection of the right sweetener for a specific use depends not only on the cost, but also more importantly on the health and safety, the sweetening potency, the effectiveness under various physical conditions such as cooking temperature (heat stability) and pH, as well as other unwanted tense of tastes of the sweetener.
