How much does straw green storage add urea, and what is the effect of adding urea to silage?

One ton of straw only needs to add 1 kg of urea.

Urea is converted into ammonium bicarbonate.

Later, it is easy to decompose and volatilize on the calcareous soil, which can cause nitrogen loss, therefore, after urea application, it is necessary to apply deep covering soil in time.

with silage. MethodAfter the autumn harvest, the corn straw that is still green or partially green is preserved for a long time, which can preserve its nutrients well, and the texture becomes soft, has a fragrance, can increase the appetite of cattle and sheep, and solve the shortage of forage in winter and spring. At the same time, the production of silage saves half of the floor space compared with stacking the same amount of hay, and is also conducive to fire prevention, rain prevention, mildew prevention and the elimination of crop pests on the straw.

Straw silage can be treated with biological starter culture, such as using Nongshengle straw starter culture to ferment the effect is good. The method of adding urea belongs to ammoniation treatment, and ammoniation treatment has many shortcomings, 1. The utilization rate of ammonia is low, only about 50%, and the rest of the ammonia is put into the air after opening the ammonia cellar, causing certain environmental pollution, and has certain harm to people and animals. 2. The types of livestock fed have certain limitations, and ammoniated straw is only suitable for ruminant livestock, cattle, sheep, etc., and is not suitable for feeding single-stomach livestock horses, donkeys, mules, etc.

3. Feeding ammoniated straw alone, without other feed or nutritional additives, livestock are prone to nutritional deficiency symptoms.

Biotreatment is recommended. Nongshengle straw starter can ferment corn stalks, wheat stalks, potato vines, peanut vines, sugarcane leaves, grass, artemisia, alfalfa, etc., with a water content of between 60-70, which can be used as fermentation raw materials. Method:

Spray the cleaned container with 500 times Nongshengle fermentation broth, and then chop the raw materials and materials into it, spray the Nongshengle fermentation broth once every 10 cm high until it is full, and then steadfast, especially the edges, and finally spray more Nongshengle fermentation broth on the material surface, cover it with plastic film, seal and ferment for about a month, and when the silage is fermented and mature, it can be used when it has aromatic or pickled vegetable flavor. If the surface layer is black or has a rancid smell, the surface layer should be discarded, and then taken from top to bottom, layer by layer, and covered tightly in time after use. Whether the moisture content is moderate is an important condition that affects the quality of silage, pay attention to the connection of water between the layers, and there shall be no sandwich layer, (the moisture content of silage is not dripping by hand, and there is obvious moisture after loosening).

Silage feeding, the initial should not be more, livestock and poultry to have adaptation time, can be mixed with a part of concentrate or compound feed, livestock and poultry adapt to gradually increase the amount. Female animals should not be fed more in the later stages of pregnancy.

Dear, hello change finger: urea can be added to the fermented and matured silage. Urea is mainly added to reduce the excessive production of ethanol and lactic acid in silage production.

By adding urea, we can avoid too acidity of silage ingredients, enjoy the benefits of corn feed silage, and avoid the *** caused by excessive acidity. Thank you for your consultation and inquiry, I hope this service can help you, you can click on my avatar to follow me, and if you have any questions in the future, you can consult me again, and finally wish you a happy life! <>

Hello dear, it is a <> that can add urea

The method of adding urea to silage: before the silage starts, first prepare urea into a 25% (that is, 100 kg of water, add 25 kg of urea) solution, store Qing fiber in a certain container, and then talk about the difference in silage, while using a micro sprayer to spray urea liquid on the surface of corn straw. The amount of spraying is land-containing:

20 kg of urea solution 25% per ton of silage corn stover. While spraying, while loading the cellar, it is required to spray evenly. Finally, I wish you a happy life.

Since the microorganisms in the rumen of dairy cows can directly utilize nitrogenous compounds such as urea, an appropriate amount of urea can be added to the silage to increase the nitrogen content in the silage and improve the quality of the silage. The appropriate amount of urea is silage raw material, that is, 5 kg of urea per 1000 kg of silage raw material. The crude protein content of silage sedan feed increased by 4% (calculated according to the dry matter content and leakage).

After the urea is added to the corn silage, the crude protein content can be increased from the original to the original one, which can roughly meet the protein needs of adult cattle. When adding urea to silage, the urea is dissolved first, and the urea liquid is evenly sprayed on the chopped silage raw material during the silage process, and it can be fully stirred.
