Many people don't know much about the efficacy of urea and ammonium bicarbonate, so especially for "selecting phobia patients", the use of urea for winter crop fertilization or ammonium bicarbonate is a big problem. Let's analyze it in detail. Which is better.
Crops are fertilized in low temperature seasons such as winter and early spring. The application of ammonium bicarbonate is better and more effective than urea. Ammonium bicarbonate belongs to ammonium nitrogen fertilizer. It can be directly absorbed and utilized by crops after being applied to soil. Urea belongs to ammonium amide. It needs to be converted into ammonium nitrogen by urease secreted by urea bacteria in soil to absorb roots.
Ammonium bicarbonate is rarely volatilized at temperatures below 20 ° C. After being applied to the soil, ammonium ions can be rapidly adsorbed by the soil colloid, and its adsorption force is 8 times that of urea. Therefore, it is not easy to lose with water. When urea is applied to the soil, it exists in a molecular state before it is converted into ammonium nitrogen, which is difficult to be adsorbed by the soil colloid and is easily lost.
After testing, the application of ammonium bicarbonate in winter wheat fields is 1~1.5 times higher than that in high temperature seasons.

A medium-sized cob of corn provides more than 10% of our daily dietary fibre requirements.
There are two types of dietary fibre - soluble and insoluble - and sweet corn contains both.
According to the American Heart Association, dietary fibre as part of an overall healthy diet can help lower blood cholesterol levels and may reduce the risk of heart disease. It is insoluble fibre that binds to cholesterol, preventing it from being absorbed into the bloodstream.
Insoluble fibre is responsible for promoting regularity and helping to prevent constipation by speeding up the passage of food and waste through the intestines and absorbing water to keep stools soft. Insoluble fibre has been shown to reduce the risk of haemorrhoids.
Fibre-containing foods such as sweetcorn also help to provide a sense of satiety and may therefore help to suppress appetite and aid weight management.
Dietary fibre has also been linked to a reduced risk of type 2 diabetes. A diet rich in fibre helps patients manage their disease.
Fibre is fermented by bacteria in the colon. Promising studies are underway to determine the health-promoting effects of fibre fermentation breakdown products, for example, short-chain fatty acids, which may help to maintain a healthy gut.
