According to the soil characteristics, alkaline soil can be applied, and acidic or physiologically acidic nitrogen fertilizers such as ammonium sulfate and ammonium chloride can be applied. In addition to neutralizing the alkalinity in the soil, they can form ammonium nitrogen which is easily absorbed by the crop; On acidic soils, alkaline or physiological alkaline nitrogen fertilizers such as urea, sodium nitrate, calcium nitrate, calcium ammonium nitrate or lime nitrogen may be used. On the one hand, they reduce the acidity in the soil and on the other hand form nitrate nitrogen which is easily absorbed by the crop under acidic conditions. It is not advisable to apply chlorine-containing ammonium chloride in saline-alkali soil to avoid increasing salt and affecting crop growth. The fertile soil should have less nitrogen application, and the soil fertilization capacity can be less fertilized. On the contrary, the nitrogen application rate should be increased appropriately, and it should be applied in several stages.
According to crop types and growth conditions, the demand for nitrogen is different for various crops. For example, crops such as sugar cane and leafy vegetables require more nitrogen, while crops such as rice, corn and wheat require medium nitrogen, while legumes have nodules. The bacteria fix the nitrogen in the air and therefore require less nitrogen. The response of different crops to nitrogen fertilizer varieties is also different. For example, ammonium fertilizer is applied to rice, especially ammonium chloride, ammonium bicarbonate and urea. Potato application of ammonium sulfate works well. Avoid chlorine crops such as tobacco, starch crops, grapes, etc. should be applied less or not. Most vegetables have a good effect on the application of nitrate nitrogen fertilizer. The effects of applying nitrogen fertilizer at different growth stages of crops are also different. In the critical period when the crop needs fertilizer, such as fertilization in the critical period of nutrition or the maximum efficiency period, the yield increase effect is significant. For example, corn needs the most nutrients before and after heading and flowering, and heavy application of panicle fertilizer can significantly increase yield. Therefore, according to the requirements of crops for nutrients, mastering the appropriate fertilization period and quantity is the key to effective application of nitrogen fertilizer.
According to the nature of nitrogen fertilizer, ammonium bicarbonate and ammonia water should be applied to cover soil to prevent evaporation. Because they are all quick-acting fertilizers, they are not easy to lose in the soil, so they can be used as base fertilizer and top dressing. They are suitable for application in paddy fields and dry land. The nitrate nitrogen fertilizer has great mobility in soil and fast fertilizer efficiency, which is suitable for dryland topdressing. The nitrogen in urea is present in the amino state. Generally, it needs to be transformed in the soil, and the crop can be absorbed in large quantities. Before the conversion, the fertilizer has no ammonium nitrogen fertilizer and nitrate nitrogen fertilizer. The topdressing should be 3 to 5 days ahead of the general fertilizer. It is used as a seed fertilizer, but urea is the most ideal for top dressing. It is suitable for all kinds of soils and various crops. In summary, the method of application should be considered in terms of the characteristics of the nitrogen fertilizer.
Combined with an appropriate amount of phosphorus and potassium fertilizer in the soil lacking effective phosphorus and available potassium, the effect of single application of nitrogen fertilizer is very poor, and the application of nitrogen fertilizer may also reduce production. Because in the absence of phosphorus and potassium, proteins and many important nitrogen-containing compounds are difficult to form, seriously affecting crop growth. Experiments in various places have proved that the application of nitrogen fertilizer with appropriate amount of phosphorus and potassium fertilizer has a significant effect on yield increase.

What is Bidet Sprayer?
A bidet shower is a hand-held triggered nozzle that is placed near the toilet and delivers a spray of water used for anal cleansing and cleaning of the genitals after using the toilet for defecation and urination. The device is similar to that on a kitchen sink sprayer.
Is a bidet sprayer worth it?
Because they are hooked up directly to your plumbing system, they require professional installation, usually as part of a bathroom renovation. Veteran bidet users point out that the money you save on toilet paper means a bidet installation will fairly quickly pay for itself - and yes, they say, bidets are worth it!
How to Use a Hand Held Bidet Sprayer
1. Locate and grab the bidet sprayer next to the toilet.2. Open the shut-off valve to allow water to flow to the sprayer.
3. The method of use for the hand held bidet becomes a personal choice.
4. Lightly squeeze the trigger on the nozzle to start spraying.
5. Check cleanliness with toilet paper.
